| Abstract | Fathead minnows (Pimephales promelas) were exposed to 3,4-dichloroaniline in three acute exposures and two early life-stage exposures. Mean LC50's were 10.8, 9.37, and 7.58 mg/l at 24, 48, and 96 hr, respectively. In the first early life-stage test, control fish were smaller than fish exposed to 15.1 micrograms/l 3,4-dichloroaniline, and due to their smaller size, the Maximum Acceptable Toxicant Concentration (MATC) was between 15.1 and 26.0 micrograms/l. In the second early life-stage test, in which control fish were larger, a concentration of 5.10 micrograms caused no observed adverse effects while a concentration of 7.10 micrograms/l resulted in reduced growth.
