title: Estimation of ambient chronic toxicity in a polluted creek system.
abstract: Ambient water toxicity estimations were conducted in Piles Creek as part of an ecological risk assessment study. This creek is part of a highly polluted estuarine system located near Linden, New Jersey. An upstream and a downstream site in the creek were evaluated for effects on survival, growth and sexual maturity of the estuarine mysid, Mysidopsis bahia. Manasquan Inlet, Manasquan, New Jersey, served as the reference site. Seven-day screening toxicity tests were conducted once a month over a three month period. Results indicate that survival of mysids was not affected in any toxicity test. Mysid growth was significantly reduced at both of the test sites, in two out of three trials. Sexual maturity was shown to be adversely affected in mysids exposed to ambient waters from both test sites throughout the duration of the study.
