Not a shocker. The Wall Street Journal reports today that a new study has found toxic chemicals in household dust. (Ed note: WSJ subscription required.) The good people at Clean Production Action tested "baseball-sized" clumps of dust taken from vacuum cleaners around the country. The upshot: they found trace amounts of nasty things like polybromenated diphenyl ethers, but were unable to prove that these were harmful to humans. (They don't sound too good for you though do they?) Best line in the article: writer Jim Carlton notes that commercial cleaners contain alkylphenols, "a chemical class that has been linked to sexual deformities in trout." Ouch. How many times to we have to tell you to go green with your detergents?
