The urinary level of phenolic compounds may be the key for establishing an index of exposure to pesticides containing this moiety as an easily hyrolyzed or metabolized portion of the molecule. A method has been developed for quantitating ten halo- and nitrophenols in rat urine which could result from exposure to and subsequent metabolism and excretion of a broad spectrum of pesticides. The procedure involves acid hydrolysis, extraction, derivatization, silica gel chromatography, and electron-capture gas chromatography. Male rats fed pesticidal compounds containing halo- and nitrophenol moieties at levels varying from factors of 0.00001 to 0.01 of the LD50 were used to establish the usefulness of this procedure for determining the extent of exposure to the biodegradable pesticides.
