Energetic and behavioral responses by the common goby, pomatoschistus microps (kroyer), exposed to linear alkylbenzene sulfonate

摘要

The acute toxicity of linear alkylbenzene sulfonate (LAS) on the common goby (Pomatoschistus microps), an estuarine fish, was established during a 96-h static exposure. The median lethal concentration was 2.6＋0.49 mg LAS/L (mean±95/100 confidence limit). The acute behavioral responses to LAS at different concentrations were excess mucous sercetion and apathy at 1.0mg/L; air gulping, distension of the mouth and opercula, change in pigementation, and erratic swimming at 2.0 to 3.0 mg/L; and loss of balance and reactivity at >=4.0 mg/L.
