The 1976 Toxic Substances Control Act (TSCA), enacted in 1976, is widely considered a failure. When enacted it enabled some 62,000 chemicals (many linked to hormonal, reproductive and immune problems, cancer and a plethora of environmental problems ) to escape testing. Another 22,000 untested chemicals -- found in everything from cleaning and personal care products to furniture, building materials, electronics, food and drink containers, even kids’ toys -- have come onto the market since.

Dear EarthTalk: What is happening to update and reform the Toxic Substances Control Act of 1976, which I understand is considerably outdated and actually permits the use of thousands of chemicals that have never been adequately tested for safety? — Henry Huse, Norwalk, CT

According to the Natural Resources Defense Council (NRDC), a leading environmental research and advocacy organization, upwards of 80,000 chemicals commonly used in the United States have never been fully assessed for toxic impacts on human health and the environment. “Under the current law, it is almost impossible for the EPA [U.S. Environmental Protection Agency] to take regulatory action against dangerous chemicals, even those that are known to cause cancer or other serious health effects,” reports the group.

1976’s Toxic Substances Control Act (TSCA) was intended to protect people and the environment from exposure to dangerous chemicals. But the standards at that time dictated that only those chemicals deemed an “unreasonable risk” were subject to testing and regulation. When the law went into effect, some 62,000 chemicals escaped testing and most have remained on the market ever since. In the interim, however, we have learned that many of them have been linked to hormonal, reproductive and immune problems, cancer, and a plethora of environmental problems.

And since 1976, an additional 22,000 chemicals have been introduced without any testing for public or environmental safety. Some of the potentially worst offenders can be found in cleaning and personal care products, furniture, building materials, electronics, food and drink containers, and even kids’ toys.

“The law is widely considered to be a failure and, most recently, the Environmental Protection Agency’s own Inspector General found it inadequate to ensure that new chemicals are safe,” reports NRDC, which is not the only group concerned about beefing up TSCA. The Safer Chemicals, Healthy Families Coalition includes more than 200 nonprofits—including Physicians for Social Responsibility, the U.S. Public Interest Research Group (USPIRG), the Environmental Defense Fund and the Lung Cancer Alliance, among many others—representing a collective membership of more than 11 million individual parents, health professionals, advocates for people with learning and developmental disabilities, reproductive health advocates, environmentalists and businesspersons from across the country.

By banding together, coalition leaders hope to convince Congress to fix the problem by finally updating TSCA and creating the “foundation for a sound and comprehensive chemicals policy that protects public health and the environment, while restoring the luster of safety to U.S. goods in the world market.”

Specifically, the coalition is lobbying Congress to revamp TSCA so that the most dangerous chemicals are phased out or banned outright and that others are tested and regulated accordingly, all the while ensuring the public’s right-to-know about the safety and use of chemicals in everyday products. Also, the coalition is calling for federal funding to expand research into greener alternative chemicals to replace those with known health hazards.

There is a social black cloud surrounding the use of polyvinyl chloride (PVC), a type of plastic used to make everyday products. When produced or burned, PVC releases several toxins into the air, which can potentially harm our immune and reproductive systems.

PVC is used in the construction of everything from pipes to pool toys, and is easy to spot (check any plastic product for a recycling symbol with the number the three in it). Companies like Microsoft and Mattel have abolished the use of PVC in their packaging for years now, but it’s still one of the most widely used plastics in North America.

The presence of PVC in toys has been of high concern for parents over the past several years. Parents very rarely check to see if toys they purchase for their children contain PVC, and therefore many children are unknowingly exposed to phthalates, which are used to soften PVC to make it more durable, when chewing on a toy. Though the exact effect is unknown, young people would be more prone to any sort of health issue caused by phthalates.

The Environmental Protection Agency (EPA) has recently begun cracking down on companies that irresponsibly handle PVC. In early December, the EPA and the Justice Department came to a $12 million settlement with Shintech Inc., the largest manufacturer of PVC in the U.S., and it’s subsidiary K-Bin Inc., demanding they clean up their facilities in Freeport, Texas after determining they violated the Clean Air Act, the Resource Conservation and Recovery Act (RCRA) and the Clean Water Act.

“It is imperative that business and industry do their part to minimize the possible harm their operations may cause to our environment,” said EPA Regional Administrator Richard E. Greene in the DOJ report. “This agreement will ensure corrective action is taken and provide added benefits to the environment through supplemental projects.”

The companies were fined $2.6 million and ordered to spend $4.8 million to decrease chlorofluorocarbon emissions and better hazardous waste management at their Texas plants. The remaining $4.7 million will be spent on supplemental environmental projects as well as renovations to ensure PVC emissions are reduced by 10,000 pounds, the DOJ reports.

The supplemental projects include funding the addition of at least 300 acres of wetlands and forest to the Austin Woods preserve, as well as aiding a new Houston recycling program that will help to ensure the proper disposal of appliances containing ozone-depleting refrigerant.

The EPA is committed to help reduce PVC emissions, while many companies are committed to lowering the usage of PVC in their products.

“It’s not something you want in a product,” said Greenpeace member Jack Desena. “In small doses the phthalates aren’t a big deal, we all come in contact with them on a regular basis. But the manufacturing, processing and disposal of polyvinyl chlorides is the real problem. When you process them they release so many toxins into the air. ‚ It really rips apart the environment.”
