Early life stage toxicity tests with a saltwater fish: effects of eight chemicals on survival, growth, and development of sheepshead minnows (Cyprinodon variegatus)

Journal Article · · J. Toxicol. Environ. Health; (United States)

Flow-through, acute (96-h), and early life stage (28-d after hatch) toxicity tests were performed with eight chemicals on a saltwater fish, sheepshead minnows (Cyprinodon variegatus). Chemical effects on survival, growth, and development were determined. Maximum acceptable toxicant concentrations (MATCs) were >3.2<7.7 mg/l for toluene, >0.52<0.97 mg/l for acenaphthene, >80<156 mg/l for isophorone, >10<16 mg/l for 4-nitrophenol, >4.8<8.5 mg/l for bromoform, >0.39<0.79 mg/l for 1-chloronaphthalene, >0.09<0.18 mg/l for 1,2,4,5-tetrachlorobenzene, and <0.36 mg/l for 2,4-dichloro-6-methylphenol; application factors were 0.25-0.59, 0.17-0.31, greater than or equal to 0.57, 0.31-0.50, greater than or equal to 0.68, greater than or equal to 0.56, 0.27-0.54, and <0.10, respectively. Test results reported here were compared with results of static, acute toxicity tests conducted previously with six species of aquatic organisms and the same chemicals.
