Results of freshwater exposures with various chemicals

Abstract

Acute flow-through and static renewal exposures with biphenyl, butachlor, carbazole, dibenzofuran, 3,3'-dichlorobenzidine, 1,2- epoxyethylbenzene (styrene oxide), isophorone, isopropalin, oxychlordane, pehtachloroanisole, tetrabromobisphenol A, tetrachlorobenzene, and 1,2,3- trichloropropane were completed using the fathead minnow (Pimephales promelas). Acute static renewal exposures with butachlor, carbazole, .3,3'­ dichlorobenzidine, 1,2-epoxyethylbenzene, isopropalin, oxychlordane, pentachloroanisole, and tetrabromobisphenol A were completed using the freshwater organism Daphnia magna. Acute and chronic (21-day) static renewal exposures with dichlorovos, carbaryl and propoxur (baygon) were also completed using Q. magna. An acute 96-hr flow-through and two early life-stage (28- days) exposurers were also completed with dichiorovos using the fathead minnow.
