Acute and chronic aquatic bioassays were conducted with a variety of organisms using parathion (0,0-diethyl 0-(p-nitrophenyl) phosphorothioate) as the challenge compound. Acute LC50 values ranged from a low of 0.38 micrograms/l in invertebrates to a high of 2.0 mg/l in freshwater fish. Non-lethal effects were documented in bluegill and brook trout chronically exposed to parathion concentrations in excess of 0.17 micrograms/l and 32.0 micrograms/l respectively. Chronic exposure of fathead minnows to concentrations of 4 micrograms/l resulted in deformation and reproductive impairment. Bioconcentration of parathion in freshwater fish tissue ranged from five to several hundred times that of the exposure water. Chronic no effect concentration of parathion for D. magna was 0.08 micrograms/l, for G. fasciatus less than 0.04 micrograms/l and for C. tentans less than 3.1 micrograms/l.
