Acute and chronic toxicity of hydrogen sulfide to the fathead minnow, Pimephales promelas
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. 5 tables.
