A Longer List


Eight new substances — including formaldehyde and styrene — have been added to the US Department of Health and Human Services' Report on Carcinogens, bringing the total number of chemicals in the report to 240. Formaldehyde was named as a known carcinogen, while styrene is anticipated to be a carcinogen. Formaldehyde, The New York Times says, is abundant, found in items as diverse as particle board, hair care products, and embalming fluid. "It's the smell in new houses, and it's in cosmetics like nail polish," says Otis Brawley, the chief medical officer of the American Cancer Society. "All a reasonable person can do is manage their exposure and decrease it to as little as possible. It's everywhere." Styrene, too, is found in many items like boats and car parts, but usually at lower concentrations, and as such is more of an issue for workers who build those items, rather than the consumers.
