Summary:
Four pollutants found in house dust add to the ability of a common household insecticide to inhibit an enzyme important in neurologic function in humans. Building on substantial evidence that the insecticide chlorpyrifos inhibits cholinesterase, a biochemical critical for nerve cell transmission, researchers at the Johns Hopkins School of Public Health found that pollutants in house dust increase this adverse effect in studies with purified enzyme.

Building on substantial evidence that the insecticide chlorpyrifos inhibits cholinesterase, a biochemical critical for nerve cell transmission, researchers at the Johns Hopkins School of Public Health found that pollutants in house dust increase this adverse effect in studies with purified enzyme. The four pollutants, polycyclic aromatic hydrocarbons (PAHs) that are among the most abundant components of house dust, are pyrene, benzo(a)pyrene, fluoranthene, and anthracene. The study appeared in the April 1999 issue of Toxicology Letters.
