Fathead minnow larvae (Pimephales promelas) were exposed to triphenyltin hydroxide (TPTH) during brief (single pulse) or continuous exposure in 96-h and 30-day toxicity tests. The continuous exposure 96-h LC50 value was 7.1 microg/liter. Brief exposures for 12 to 72-h gave 96-h LC50 values that ranged from 61.8 to 6.0 microg/liter, respectively. The continuous exposure 30-day chronic effect concentration, based upon reduced growth, was 0.23 microg/liter. Survival was significantly reduced at 2.0 microg/liter. Brief exposures for 24, 48, and 72-h in 30-day tests significantly reduced survival and growth at 13.0, 13.0, and 60.0 microg/liter, respectively. It is suggested that both toxicant concentration and exposure duration are important factors to consider in the risk assessment of potential pesticide hazards in the environment.
