Toxic effects of molecular hydrogen sulfide to eggs, fry, and juveniles of the fathead minnow, Pimephales promelas Rafinesque, were determined in flow-through bioassays. The 96-h LC50 of laboratory-cultured juveniles at 20/sup 0/C was 0.0243 mg/l H/sub 2/S. Fry were approximately twice as sensitive. Response with temperature in wild stock juveniles varied from a 96-h LC50 of 0.7754 mg/l at 6.5/sup 0/C to 0.0423 mg/l H/sub 2/S at 25/sup 0/C. In chronic exposure to H/sub 2/S from egg through two generations of laboratory-cultured stock in flow-through bioassays, adverse effects on growth, survival, and fecundity occurred above 0.004 mg/l H/sub 2/S. Chronic exposure of wild stock up to 346 days caused adverse effects on growth and survival above 0.008 mg/l H/sub 2/S. At comparable temperatures apparent safe levels with long exposure were five- to sevenfold lower than the 96-h LC50 for both stocks.
