Flame retardants sound like a good idea to prevent our couches and computers and carpets from combusting. Yet these chemicals also accumulate and linger in our homes, sometimes winding up in household dust at levels of health concern. That was one of the central findings of a recent Silent Spring Institute study, the first to test for a wide range of flame retardants in homes.
Institute researchers tested for 49 flame retardant chemicals in household dust, the main route of exposure for people and especially for children. Forty-four chemicals were detected. Most homes had at least one chemical above a federal health guideline. The flame retardants found in house dust include carcinogens, hormone disruptors, and chemicals with unknown safety profiles.
