Abstract
Flow-through, acute (96 h) and early life stage (28 days after hatch) toxicity tests were performed with 8 chemicals on a saltwater fish, sheepshed minnows (C. variegatus). Chemical effects on survival, growth and development were determined. Maximum acceptable toxicant concentrations (MATC) 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, .gtoreq. 0.57, 0.31-0.50, .gtoreq. 0.68, .gtoreq. 0.56, 0.27-0.54 and < 0.10, respectively. Test results were compared with results of static, acute toxicity tests conducted previously other aquatic organisms [alga, water flea, bluegill and mysid shrimp].
