Attention: Update on PVC pipe and Chloramines in the Santa Clarita Valley
http://www.the-signal.com/news/article/17365/
If you click on the link listed above, you can find some information about the Clean Water Pipe Council’s mission, as well as information on the kinds of water pipe being used and not used in the Santa Clarita Valley. The article was featured in The Signal, a local newspaper in Santa Clarita Valley, and despite some errors in information it is great conversation-starter on the issues being faced both in that particular area of California and throughout the U.S. As is mentioned in the article, there are water agencies that don’t use PVC pipe, such as Castaic Lake Water Agencyand Valencia Water Company. These water companies are using green alternatives such as ductile iron or steel pipe. Not only are these pipes more energy efficient, but they also keep the drinking water in the beautiful Santa Clarita Valley healthy and lead-free.
However, at the same time as some water agencies are going green and healthy, many others are still using PVC pipe to deliver potable water. These agencies include Santa Clarita Water Company and Otay Water District (in San Diego).Often these companies are also using chloraminesto disinfect the water. Recent research has come out showing that the use of chloraminesin PVC pipes begins a harmful process beginning with the chloraminebreaking down into ammonia –which supports the growth of bacteria. These bacteria, in turn, lower the pH of your drinking water, turning it acidic. Acidic water goes to work on fixtures, such as brass, in home water systems, and can result in the leeching on toxic lead into drinking water.
Many water authorities are unaware of, or are only just learning of these processes, so they could be in effect in your water supply. As can be read in the article, often the “solution” is to turn on your water supply for a period of time before drinking. Not only is this a halfway ameliorative, but a true solution exists –Lobby Your City Government For Clean Water Pipes! Several environmentally friendlyandhigh-efficiency options are available. As we mentioned above, not only are the green alternatives great for the health of your family and community, they are also highly energy efficient when compared to similar diameter PVC pipe. These energy savings equal a smaller carbon footprint and a more economical solution to water delivery. Stay tuned on our Facebook account, as well as on our website for our next article, which will go a little deeper into issues revolving around energy efficiency.For more info please come the Clean Water Pipe Council at

The news just gets worse and worse in terms of the hazards Vinyl Chloride. Cautionary post indeed.
Vinyl Chloride itself is a flammable, colorless, sweet smelling gas. What does that incorporate? What’s a protocol that would kind of fit that?
Dr. However, OSHA has classified vinyl chloride as a hazardous chemical with a permissible exposure limit of 1 ppm (part per million), at which level it is impossible for the human nose to register a smell. Williams: Let me first give you a couple of questions on testing your viral immunity for your listeners. Thus, if a person were able to smell vinyl chloride this would be indicative of an egregious overexposure.

Over at Green Living Ideas they are discussing the best way to make your home energy efficient - starting with your windows. While PVC might be slightly cheaper in the short-term, there are some alternatives that last longer - reducing life-long cost and are much safer for your loved ones and the environment.
If windows are the eyes of your home, and eyes are the windows to a soul, shouldn’t your home’s windows be clean and green? This blend of old adages highlights the benefits of installing energy efficient windows from a design perspective, though resulting energy savings for the environment and cost savings for the owner are probably reason enough!

Workspace Design Principles lists some alternatives to PVC in the areas of pipes, siding, doors and windows. Great tips if you are renovating your home.
Polyvinyl Chloride which is commonly know as PVC or Vinyl is one of the most commonly used synthetic or to say non biodegradable material. The production, use and disposal of PVC are all very hazardous to the environment and human health. The effects are many, to name some ; cancer, heart disease, birth defects… The list goes on.There are many alternative to PVC, some of them more expensive and may be even labour taking. But health and the preservation of environment is most important. So here we have some alternatives for PVC…

These PVC- and BPA-free dog toys can keep your pet safe, but also your child. After all, your little one can’t tell the difference between a safe toy and one that is not, so keep your whole household safe.
As we’ve mentioned before, PVC’s entire life cycle - from production through use and disposal - has a negative impact on human health and the environment. We’re already exposed to enough lead in soil, cosmetics and children’s toys, and whether we like or not, our children play with the dogs toys . . .
Consumer Goods
This comes from Safbaby and is a Q and A session with Mike Schade from the Center for Health, Environment and Justice (CHEJ). Mr. Schade points out that phthalate-free PVC is not the answer, since rigid PVC such as that are used in lunchboxes contain dangerous ingredients such as lead.
Q. Safbaby: Some toys are labeled “Phthalate-free”, is this enough or should I only purchase PVC-free ?
A. Mike: Certainly, phthalate free toys are a step in the right direction, but even PVC toys that are phthalate-free may potentially contain other potentially harmful chemical additives. For example, lead has been found in a number of PVC children’s toys and back-to-school products such as lunch-boxes. Many companies have substituted lead for other “stabilizers” such as organotins which may be harmful over time. Some organotins affect the central nervous system, skin, liver, immune system and reproductive system. Since the organotins are not 100% bound to the polymer, they can easily migrate from within a PVC product to the surface.
The best bet is to look for toys that are 100% PVC-free. After all, it’s better to be safe than sorry.
Here’s a post from The Soft Landing Blog which contains a downloadable comparison of Baby Bottles so you can keep your little one PVC- and BPA-free.

Article from Huffington Post on PVC in Yoga Mats, as well as other consumer products. When you’re taking care of your body and soul, make sure to check the label on your mat.
PVC became the plastic of choice because it’s cheap, but considering the impacts on environmental and human health, it’s actually priceless. PVC can’t be recycled due to the toxins embedded within it, and when it’s incinerated or buried in landfills it releases dioxin, a known carcinogen. Pthalates have been known to impact boy bits in utero and swimmers once the boys become men, and lead and cadmium damage our brains and never break down. Not exactly the impermanence we’re after in yoga.
After reading the Huffington Post article, check out this post from Feelgood Style on some safe alternatives for you to use.
Still not convinced about switching to a green mat? Well, remember the non-eco sticky mats are made of PVC (polyvinyl chloride) plastic containing cancer-causing dioxins that is released into the atmosphere and in addition, softening PVC products for mats includes more harsh toxic chemicals (such as Phthalates) which leach into the air. So make the switch, invest in an earth friendly mat instead, you are worth it!
Blog post from Ecolect, on several corporations plans to ban PVC toys. Toys “R” Us is moving farther than most, working towards a ban on PVC plasticizers, i.e., phthalates.
Toys “R” Us is taking their initiative to the next level, announcing that they will be phasing out any toys containing phthalates in their juvenile product lines. Phthalates are the chemical compounds that soften PVC, turning it from a hard and rigid material to a soft and flexible material. Aside from being used in toys, phthalates are commonly used in the production of paints, nail polish and adhesives. Added phthalates in PVC is being discovered to cause unusual hormonal activity, birth defects and other health risks, especially to children as their bodies are still in the process of growing. In 2009, the state of California will begin acting on serious plans to heavily restrict the use of phthalates in toys for children.
A personal post on BPA and plastic water bottles, including information on how you can distinguish between types of plastics, and, more importantly, the reasons why you should.
Essentially from my knowledge of what BPA is it is a chemical that has elevated levels of Estrogen in it. And it is still in debate as to how high the level of Estrogen is. Some people are saying it is high enough to cause reproductive defects in Men & Women and it does have negative developmental effects on Children & Fetuses. Oh and also, they are just not in the water bottles they are also in Baby Bottles. Personally, I don’t know how high the level of BPA is that we are drinking out of the water bottle but it does not sit well with me at all to know that it could possibly be doing harm to our family. And I don’t want it to be in my families bodies. We are constantly teaching Sam the importance of eating healthy and making good choices in what he eats. So how is any different, to give him a bottle that could be having negative effects on his development to him or any baby and tell them to drink out of it?
Green back to school products. Offers a great list of products that are free from BPA, vinyl, PVC, phthalates and lead.
With new research and awareness regarding product manufacturing, it’s important to choose products that are free from BPA, vinyl, PVCs, phthalates, and lead.
Choosing eco alternatives during your shopping adventures is a great way to introduce green concepts at an early age.
As kids go back to school, they may be learning about how to preserve and protect our environment. If children are exposed to this information beforehand, they can connect on a personal level and feel like they’ve made an important contribution…
A post from Family Safety and Health on PVC and Lead-Free lunch boxes. Contains a few links to sites where parents can find PCV-Free products for their children.
Lead as you know is toxic to children (and adults for that matter), so it’s important that the place their lunch is stored in is lead-free. Lead can also be ingested from your child touching the bag and then their food. For a list of manufacturers who have agreed to produce lead-safe lunch boxes, check out the CEH’s website.
PVC is toxic as it contains phthalates and lead. The Center for Health, Environment and Justice offers a downloadable guide to PVC-free school supplies.
…it is heartening to hear that the big retailers are making some changes to improve toy and baby product safety.
Last week both Wal-Mart and Toys R Us came out with similar plans: to strengthen their toy and product safety. Toy R Us has an impressive list of objectives: to have third party screening of imported toys, dropping the “acceptable” levels of lead to 90ppm (from 600ppm), and by the end of 2008, all products for babies will not be allowed to contain phthalates. They are also phasing out the use of PVC (vinyl) in products for babies and young children. Apparently, Wal-Mart outlined similar goals.
In the past year, we have learned that toys are not as safe as we once thought. Thomas the Tank Engine and other toys manufactured in China - and the U.S. — were recalled en masse because of lead contamination. But lead is not the only toxic chemical in toys that parents are worried about. Phthalates are another family of unsafe chemicals commonly used in children’s toys such as teethers, bath books and rubber ducks to make them soft and flexible. When kids put these toys in their mouths, phthalates can leach out of the products and enter their bodies. Help us prevent harm.
This post comes from our neighbor to the north, Canada, with plenty of references to safety issues in the U.S. Specifically, the post deals with a recent study calling for a ban on PVC shower curtains, which were found to release over 100 toxic chemicals into the air, including phthalates. Here’s a snippet…
The laboratory tests of five new PVC shower curtains, released Thursday, found 108 different volatile organic compounds were released into the air over a 28-day period, including off-gassing above the recommended level in the United States for seven days.
These compounds can cause respiratory irritation, headaches, nausea and damage to the liver, kidney and the central nervous system. Some VOCs are also suspected or known to cause cancer in humans.
The shower curtains also contained phthalates (DEHP), already banned in children’s toys in California, Washington and the European Union. Canada has listed DEHP as a “toxic” substance and has recommended it be banned in children’s products, but has yet to implement the recommendation.
Nice list of plastics: which are safe and which aren’t…
#3 Polyvinyl Chloride (PVC or vinyl): Plasticizers are added to many PVC products to make them flexible. These include phthalates — suspected endocrine-disrupting chemicals (EDCs). DEHA, another possible endocrine disruptor, was found to leach from PVC cling wraps into cheese in 1998 tests by Consumer Reports. Grocery stores commonly use PVC to wrap deli meats and cheeses. Reynolds cling wrap is PVC. Appalachian Mountain spring water and some vegetable oils are bottled in PVC. And PVC’s manufacture and incineration produces highly toxic dioxins, as does the PVDC used in Saran Wrap, according to Consumers Union, publisher of Consumer Reports.
An article on Orbit strollers, which are made from materials free of PVC and other harmful chemicals.
“The company is committed to sustainability and using environmentally safe materials and practices. The company has stopped producing products that contain PVC (read why this is a good thing). All of the fabrics used in the Toddler Car Seat are tested to ensure they’re free of PBB (polybrominated biphenyl), PBDE (polybrominated diphenyl ethers), and brominated chemicals, and most are Oeko-Tex Standard 100 Certified. The company is also committed to being the first baby gear company to rid its supply chain of PVC, chrome-plating, and oil-based packaging inks.”
A manufacturer of PVC-safe products, Ecogear makes a number of backpacks and bags from eco-friendly materials and non-toxic dyes.
“Whether your next trip is by land, air or sea, you’ll most definitely be bringing at least one bag with you. If the bag you carry on your shoulders, stow under your seat or stash in an overhead bin is made from traditional materials, you might be carrying more baggage than you realize. Most backpacks and messenger bags are made with chemical-emitting PVC plastic, which is pretty nasty stuff. PVC production fuses vinyl chloride molecules with toxic metals such as lead and cadmium, which are added as plasticizers and stabilizers. Because of the chemical properties of chlorine, the by-products of PVC production tend to be far more toxic, more persistent in the environment, and more likely to build up in the food supply and the bodies of people than otherwise similar chlorine-free chemicals.
Millions of PVC cards are used everyday in a plethora of applications and industries – cutting across nearly every social and business sector imaginable. These include photo IDs for schools and companies, membership cards, hotel room key-cards, and gift and loyalty cards. But since their production is dependent on oil, a non-renewable resource, PVC cards adversely affect the environment, both in their manufacture and eventual disposal. In contrast, Corn Cards are made from corn, a readily available, renewable resource.
Key features include:
- Same familiar look and feel of standard white PVC cards.
- Identical quality and durability of printed cards.
- 100% biodegradable and no toxins released when properly disposed.
- Made from special corn type – not derived from corn used in human food supply. PVC’s use is rapidly declining, as more and more manufacturers and retailers recognize its harmful environmental effects.
A post from the blog Eat Play Love concerned with the safety of plastic water bottles. The post outlines hazards of plastic containers that contain Bisphenol-A (BPA), which is a hormone disruptor, and is found in the incredibly popular Nalgene brand bottles. The post goes on to list types of plastic that do not contain BPA.
The main concern is Bisphenol-A or better known as BPA, which is used in many baby bottles and Nalgene water bottles. BPA is considered toxic because it’s a hormone disruptor. Other plastics to avoid contain endocrine disruptors and carcinogens. Studies show the bottles are more prone to leaching when they are heated (microwave, dishwasher) and scratched or the surface has been damaged.
Health Hazards
A nice article from the Daily Record, written by Joel Liebesfeld, on the exposure to hazardous PVC found in workplaces. I’ve posted the body of the article here, as it seemed especially prescient and important.
As a society we have, for the most part, become attuned to accepting our offices and work areas as safe. Some occupations are performed in inherently dangerous environments, and generally the people employed in such positions understand the many heightened risks that they face. For example, if you worked in areas where the air was dense with sawdust or flour dust, you would be typically alerted to the dangers of explosions. Or, if you worked at removing mold growth or asbestos, you would be trained on the use of protective gear and garb. However, many substances that are potentially toxic and are indigenous to one’s surroundings seem to go relatively unnoticed.
PVC is the abbreviation for polyvinyl chloride (vinyl). PVC is a substance that throughout its life cycle releases poisonous chemicals, “such as mercury dioxins, and phthalates, which may pose irreversible life-long health threats. When produced or burned, PVC plastic releases dioxins, a group of the most potent synthetic chemicals ever tested, which can cause cancer and harm the immune and reproductive systems.” See the Web site http://www.chej.org/BESAFE/pvc/about.htm.
In the matter of PVC, the applications that are most disturbing are in many commercial buildings. Where code permits, it is used as water pipe and electrical conduit. I have often been asked why the air was so toxic with the collapse of the twin towers at the World Trade Center. Among the many reasons, was that some of the many plastics (polymers) — with many of the same properties as PVC — burned and melted, yielding a toxic soup of pulverized dust into the mixture of air. The pile of rubble that was once among the most famous skyscrapers in the world had become a literal mound of deadly debris. The city’s fire, rescue, police and emergency services who worked in the aftermath of the collapse never knew/understood the possible consequences of their efforts. While these people were at work looking for bodies or the remains of bodies, they themselves became imperiled from the leaching out of toxic substances.
It has been known for some time that PVC has been a persistent toxic pollutant. Scientists have found that PVC is an endocrine-disrupting chemical.
The Healthy Building Network stated that, “PVC is the worst plastic from an environmental perspective, posing unique and major hazards in its manufacture, product life and disposal.
Global vinyl production totals over 30 million tons per year, and 75 percent of PVC is directed to building applications.” The HBN motto is, “Advocating for environmental health and justice where we work, live and play.”
Phthalates are chemical additives that soften plastics and are used to make them more flexible. Phthalates have been used in conjunction with plastics and vinyl for some time. This popular group of chemical additives has been the subject of numerous studies in many countries. PVC plastics are labeled “Type 3″ for recycling purposes and typically leach phthalates. Type 3 recycling includes vinyl/polyvinyl chloride, food wrap, vegetable oil bottles, blister packages, etc.
Would a person move into a neighborhood and spend an appreciable part of their life there if they knew that there was a good chance that by doing so they would shorten and taint the quality of that life? An unhealthy work environment may have its personnel there for a protracted part of their lives, except that these people may never know of their continuous exposure to toxic substances.
A federal Environmental Protection Agency report concluded that New Jersey had the worst track record in the nation, accounting for more than one quarter of all unresolved Superfund cleanups more than 20 years old.
The first definition of the word security in the Random House Webster’s College Dictionary (1996) was “Freedom from danger, risk, etc.; safety.” With all the enemies that want to do us in, we need to be our own best friend and take care of that which we cannot replace — our health!
Joel Liebesfeld of Randolph is senior engineering investigator and an adjunct instructor at Fairleigh Dickinson University.
This is a post exploring federally sponsored research exploring links between hormonal abnormalities and phthalates.
“Last year, the federal government sponsored a gathering of 38 medical researchers to determine what effects BPA has on humans. The group reported that BPA acts the same way in humans as it does in animals and the levels in humans are causing negative health effects. It’s possible that BPA might be contributing to our obesity epidemic, which is already tied to early puberty. Most relevant to us: the scientists concluded that early puberty is directly linked to low-dose exposure to BPA.
Another group of synthetic chemicals, used to make plastic flexible, has been linked to early breast budding in girls. These chemicals, called phthalates, are used to make polyvinyl chloride, or PVC, (identified by a number 3) which is what many water pipes are made of. They’re also found in food wrappings, the lining of cardboard boxes that hold liquid or fatty foods, medical tubing, time-release capsules, kids’ toys, insect repellents and countless personal care products. This last category includes shampoo, lotions and deodorants. The CDC found that phthalates compose up to 3 percent of some of these products. Women of childbearing age are the group most exposed to phthalates.”
This is a nicely written post on the dangers of taking our everyday use of plastics for granted.
“So, first off, we seriously need to curb our consumption of plastic. There are growing piles of floating plastic creating islands in the oceans. The biggest one is known as the Great Pacific Garbage Patch and is larger than Texas (or Spain if you’re more Euro-centric). Aquatic species are starving as they eat the plastic thinking it’s food and then dying with bellies full of our old toothbrushes and plastic wrappers. If you want to avoid the world envisioned in Pixar’s new movie, Wall-E, make it a personal pledge to decrease your consumption. Think “Do I need this?”; “Can I get it made out of a more sustainable material?”; “Can I find an option with less packaging?”; and “Can it be recycled?”, especially considering only about 5% of plastic actually gets recycled. Still, the main question people ask themselves of late is, “Is plastic safe for my health, or my children’s health?”
Two types of plastic, polyvinyl chloride (PVC) and polycarbonate (PC), have been causing some real concerns. Two chemical ingredients, bisphenol-A (BPA) and a phthalate known as Di(2-ethylhexyl) phthalate (DEHP), are known hormone disruptors and have been detected in the blood and urine of nearly every person tested. The worst news is the youngest children tested have the highest concentrations in their bodies.”
Environmental Hazards
This post comes from the blog of the Philippine Center for Investigative Journalism and explores the dangers of our Hi-Tech waste. Hazardous waste includes PVC and heavy metals such as Lead and Cadmium.
Smith said semiconductor workers in Silicon Valley in California in the U.S. experience illness rates three times higher than manufacturing workers in other industries. Based on epidemiological studies too, women who worked in fabrication rooms experience miscarriages at a rate 40 percent higher or more than non-manufacturing workers. Silicon Valley also has more Environmental Protection Agency (EPA) Superfund sites than any other area in the country.
Healthy Child Healthy World discusses the dangers of PVC across its entire life-cycle, from vinyl chloride in production, to the inability to safely recycle PVC products. The post ends by listing a wide range of companies that are phasing out PVC in their products, as well as ways consumers can protect themselves.
PVC begins as a flammable gas called vinyl chloride, which is not only a known human carcinogen, but also releases toxic vapors in a process called “off-gassing,” which can increase the risk of liver cancer, harm the nervous system, and cause birth defects.
Studies have shown that workers in PVC facilities develop significantly higher chances of contracting multiple diseases, including a rare form of liver cancer. The pollution caused by these factories creates a huge environmental justice concern for the low-income, minority communities who reside nearby. Although it costs businesses very little to make this brittle plastic, the environment takes a toll, as PVC plants not only pollute the air, but also the water in the surrounding area, forcing many families to leave their contaminated homes and neighborhoods.
A nice breakdown of plastic resin types from National Geographic. Included tips for recycling, and known health hazards associated with plastics, including toxic vinyl chloride in PVC.
Plastic is the most widely used material in the United States, and it crops up in everything from toys to clothes to food containers. But not all plastics are created equal, particularly in regards to food storage: Some plastics can transmit chemicals into your food, while others are perfectly safe.
Before you know which type of plastic container to buy the next time you hit the store, you first need to know how to tell them apart. Plastics are typically classified by a number from #1 to #7, each number representing a different type of resin. That number is usually imprinted on the bottom of your container; flip it upside down, and you’ll see a recycling triangle with the number in the middle…
…#3 polyvinyl chloride (PVC) is often used frequently in cling wraps for meat. However, PVC contains softeners called phthalates that interfere with hormonal development, and its manufacture and incineration release dioxin, a potent carcinogen and hormone disruptor. Vinyl chloride, the primary building block of PVC, is a known human carcinogen that also poses a threat to workers during manufacture.
Post on Ruth Stringer, a scientist who has conducted many studies on the use and disposal of PVC…
Ruth Stringer, a British national who has done studies on the hazards of manufacturing, consuming and disposing polyvinyl chloride (PVC) told participants of a forum, dubbed “Usapang Plastik,” to exercise precaution in buying products made of PVC for their own safety.
The forum, organized by the waste and pollution watchdog EcoWaste Coalition’s Task Force on Plastics, discussed the potential health and environmental risk of plastics.
During the forum, it was revealed that PVC or plastic no. 3, is commonly used in food packaging, plastic wrap, toiletries and cosmetics containers, detergent bottles, shampoo bottles, beach balls, inflatable swimming pools, shower curtains, medical devices, toys, pacifiers and teething rings, which could pose great risk to public health and the environment, especially when they are being used and disposed of improperly.
Construction & Plumbing
Article from Planet Green on keeping your family safe by keeping your home PVC-free. The author lists a variety of hazards resulting from the use of the “poison plastic,” including angiosarcoma, neurological damage, and birth defects.
A 1999 study by the National Institute of Public Health in Norway found that the risk of children developing bronchial obstruction-an asthma symptom-”increased in relation to the amount of plasticizer-emitting materials in the home.” According to the authors, children exposed to PVC flooring and wall coverings in nurseries, bedrooms, and other rooms have an 89 percent higher risk of developing bronchial obstruction than kids who pitter-pattered in PVC-free homes.
And because PVC cannot be easily recycled, it’s either landfilled, where it leaches chemicals or incinerated, releasing dioxin and heavy metals again.
This is a great review of a scientific study on lead leaching and faucet corrosion. The article points out that the combination of chloramine-treated water and PVC plumbing systems, which often utilize brass faucet fixtures, can lead to the corrosion of the fixtures, resulting into heavy metals being released into water pipes.
Marc Edwards and colleagues point out that more water purification plants in the United States are using chloramine to treat water. At the same time, builders are plumbing more houses with plastic pipe, rather than copper, to cut costs. Past studies have found that ammonia formed in chloramine-treated water can trigger a series of events that corrode brass faucet components and connectors commonly used in PVC plumbing systems. Corrosion of brass (made with copper, zinc and lead) releases those metals into water pipes and makes faucets prone to failure.
Blog article on the different building materials constructed from PVC, including rigid PVC in the case of pipes. It is pointed out that rigid PVC pipes contain heavy metals such as lead, and that alternative, PVC-free materials are available for the creation of these pipes and cables.
Pipes - Rainwater guttering and drainpipes, water supply pipes, sewerage and drainage pipes, protective pipes for cables.
Approximately 90 percent of PVC pipes produced are waste pipes, protective pipes for electricity and telecommunications cable and underground drainage pipes. The rest are found in buildings as waste pipes or as mains pipes.
Pipes are made from rigid PVC (or unplasticised PVC - uPVC). Lead or tin stabilisers are often used in pipes, and red-brown pipes contain lead pigments. PVC-Free Pipes and Ducts are available.
Here’s a short post that illustrates some of the issues, and hazards, with PVC and plumbing cross-connections…
According to the EPA,
Plumbing cross-connections, which are defined as actual or potential connections between a potable and non-potable water supply, constitute a serious public health hazard. There are numerous, well-documented cases where cross-connections have been responsible for contamination of drinking water, and have resulted in the spread of disease. The problem is a dynamic one, because piping systems are continually being installed, altered, or extended.
Policy & Education
Here’s a post from a blog concerned with Recycling and eWaste noting legislation moving towards banning PVC resin in consumer packaging.
CAW sponsored AB 2505 (Brownley) passed out of Assembly Environmental Safety and Toxic Materials Committee April 15. The bill proposes to phase out the use of PVC resin in certain consumer packaging. Consumer packaging represents the largest segment of PVC in the solid waste stream, as it is virtually non-recyclable. PVC consumer packaging also presents a human health threat as it can contain high levels of phthalates and heavy metals, and is a costly and potent contaminant in the recycling stream of other, non-toxic alternative plastics.
A very informative article on the movement to phase out PVC packaging in California – includes mentions of rigid PVC and heavy metals, as well as the dangers resulting from each stage of the PVC lifecycle.
PVC packaging also often contains high levels of toxic heavy metals—one recent study found that 61% of PVC containers tested positive for Lead or Cadmium contamination. These toxins can migrate from packaging items into the human body and environment. Recognizing these threats, the California Ocean Protection Council has called for the banning of vinyl chloride from plastic packaging by 2015.
To make matters worse, PVC is virtually non-recyclable because toxicity concerns and lack of market. In fact, PVC is actually considered a serious recycling contaminant as it is nearly indistinguishable from other, non-toxic resins such as PET that are recycled. Just 1 PVC bottle can render a batch of 1,000 PET bottles unsuitable for high-end uses, costing recyclers thousands.
Hot on the heels of findings of toxic off-gassing from PVC shower curtains, this post calls for changes in out-dated legislation from the EPA.
‘“Six years after the EPA found that PVC shower curtains continue to release toxic chemicals into the air we breathe for a month or longer, our study shows that nothing has changed,” adds Lois Gibbs, CHEJ’s founder and executive director. “Something must be done to protect consumers from any potential harm these toxic chemicals cause. Wal-Mart and other retailers need to phase out these toxic chemicals.
Unfortunately phthalates have been linked to a number of serious health problems including birth defects, early puberty and testicular cancer. They have no place in our children’s toys, especially since safe alternatives exist.
