"WASHINGTON — The scientist nominated to head the federal government’s chemical regulatory program has spent much of his career helping businesses fight restrictions on the use of potentially toxic compounds in consumer goods.
That record is expected to figure prominently in a Senate confirmation hearing for the scientist, Michael L. Dourson, who critics say is too closely tied to the chemical industry to be its chief regulator.
The source of the concern is a consulting group that Mr. Dourson founded in 1995, which has been paid by chemical companies for research and reports that frequently downplayed the health risks posed by their compounds.
Four chemicals that are nearly ubiquitous in everyday products — 1,4-dioxane, 1-bromopropane, trichloroethylene and chlorpyrifos — are now under review by agency regulators to determine whether they pose a threat to public health. If confirmed, Mr. Dourson would oversee the review of some chemicals produced by companies that his firm used to represent."
