Summary results of laboratory investigations into potential chronic effects of industrial effluent discharges are presented and discussed. The sheepshead minnow (Cyprinodon variegatus) and the benthic copepod (Tisbe battagliai) were selected as test species. Toxicity tests were conducted on newly hatched (approximately 24 hours old) sheepshead minnow larvae. Survival and growth (as dry weight) effects were measured over 7 days. Two different stages of the copepod life cycle were tested: effects on adult female survival and reproduction were measured over 9 days, and naupliar survival over 7 days. The results were incorporated into an existing monitoring programme of the effluent disposal area in the North Sea. Predicted effluent dilutions in the disposal area would exceed one million times within 8 hours. This dilution is 18 and 100 times greater than the 7 day lowest no observed effect concentration (NOEC) for copepod and sheepshead minnow respectively.
