When Herbert H. Dow tapped the bromine salt deposits beneath Midland, Michigan, he launched a major chemical company and the chemistry that, more than a century later, still haunts our homes and bodies with toxic flame retardants.
Scientists shed new light on this growing chemical threat just last week, with two research teams reporting results in the prestigious peer-reviewed journal Environmental Science & Technology.
One study found that 85% of couches sampled has high levels of brominated and chlorinated flame retardants known to cause cancer, hormone disruption or reproductive harm. Some are long-lived in the environment, building up to high levels in wildlife and people.
Jenny Rottmann, a pregnant study participant who provided a foam sample from her couch cushion, responded this way: “It’s something that I’d be concerned about no matter what, but finding this out a couple days before I’m about to deliver a baby really is infuriating to me.”
The other study revealed that people are exposed to flame retardants in their homes everyday, often at levels that exceed federal health guidelines. Researchers found 44 flame retardant chemicals in household dust, which people breathe and ingest, especially small children with their frequent hand-to-mouth contact.
The chemical industry has aggressively covered up the dangers and exaggerated the effectiveness of toxic flame retardants in slowing the spread of household fires. Three small chemical companies have drawn the most heat. According to the Chicago Tribune, Albemarle, Chemtura, and ICL used misleading testimony, phony front groups and distorted science to expand and protect their chemical markets.
Little noticed so far has been the role that heavyweight chemical corporations such as Dow Chemical play in propping up the toxic flame retardant industry. Dow places a heavy thumb on the toxic scale in two ways.
First, they sit at the base of the supply chain, producing the chemicals needed to make a broad class of chlorinated flame retardants. Dow Chemical is the world’s largest producer of chlorine and epichlorohydrin, and also makes phosphorus oxychloride. These three chemicals are essential raw materials for the production of chlorinated tris (also known as TDCPP) and related chlorinated flame retardants.
In the recent science studies, TDCPP was found in 42% of all couches, more often than any other flame retardant chemical, and in 100% of household dust samples. The U.S. Environmental Protection Agency considers TDCPP a hazard for “cancer, reproductive harm, developmental toxicity, systemic toxicity, and genotoxicty in humans; and ecotoxicity and environmental persistence.” Last year, California concluded that TDCPP was known to cause cancer.
That’s why Safer Chemicals, Healthy Families asked Dow Chemical today to show its commitment to truly sustainable chemistry by agreeing not to sell its chemical raw materials for use in the manufacture of chlorinated tris. As the SCHF letter said:
“… from your powerful position at the base of the supply chain, you would send an important signal to the marketplace that fire safety goals should be met with safer alternatives to the use of TDCPP.”
Hopefully, Dow Chemical will respond more quickly and positively to this leadership opportunity than they have on a second, more systemic front.
The major chemical companies, including Dow Chemical, have perpetuated our broken federal chemical safety system for thirty-six years running. The obsolete Toxic Substances Control Act of 1976 (TSCA) keeps the public in the dark about chemical hazards and handcuffs the federal government from restricting known chemical dangers.
Last year, Dow Chemical management broke off negotiations that were heading toward a compromise TSCA reform agreement. The company has maintained steadfast opposition to the Safe Chemicals Act, despite widespread public and political support for tighter regulation of toxic chemicals in everyday products.
Dow Chemical, which spouts “solutionism” and “sustainability” as marketing mantra, has been trying hard to shake off the toxic legacy of Agent Orange and dioxin. And despite their positive spin, Dow remains wedded to chlorine chemistry (some call it ‘Pandora’s Poison’), which it uses to make more than one-quarter of more than 5,000 Dow products.
No one expects Dow Chemical to transform itself into a green chemistry company anytime soon. Dow’s current goal remains extremely modest – at least 10% of their sales will consist of products highly advantaged by sustainable chemistry, broadly defined, by 2015.
Yet, Dow does have a chance to be a real leader on the path to more sustainable, inherently safer chemistry. It’s time for Dow Chemical to get off the toxic couch by actively opposing the home invasion by chlorinated tris, and supporting the Safe Chemicals Act.
As if we don't have enough poisoning us right now, PLEASE stop spreading carcinogens!!! We should have laws that the manufacturers have to label there products toxicity, even if it is a couch. Breathing is still consuming so they should be held to the same standard. If that happened watch how quick they go out of business, and they know it.Posted by: Jessy | Dec 10, 2012 11:20:34 AM
Chlorinated tris is also used in spray foam insulation, which is also similar to your couch foam. The amount of sprayfoam in a home is huge compared to your couch= too much tris in home.Posted by: greenwashed | Dec 6, 2012 12:12:34 PM
Homes are showing high levels of TDCPP in air tests from spray foam homes. This is a huge concern, but one that is overlooked because the spray foam companies market their product as inert (which means nothing by definition of ingredient terminology). The chlorinated tris leaches out of the Spray foam during install, while curing (some foams never fully cure+high chemical off gassing for life of product - yuk), and for the life of the foam. Even if the spray foam is in your walls or attic, the tris from shaved or touched or broken or degraded foam becomes airborne and attached to dust as it moves around your home. So...your kids, dog and yourself touch it, eat it and breath it. Spray foam also off-gases a toxic soup of other known carcinogens, endocrine disruptors, ect ect. Before using this 'great green' toxic building material, please do your own research.
