| Abstract: | The influence of seasonal temperatures (15–22°C) on chlorine (0.00, 0.15 and 0.30 mg/L total residual chlorine),  T (2, 6 and 10°C), and exposure duration (0.08, 2.0 and 4.0 hr) interaction studies simulating power plant entrainment and effluent discharge conditions was evaluated for opossum shrimp,Neomysis americana and amphipods,Gammarus sp. Seasonal temperature was an important factor affecting the toxicity of the three treatment variables with both of these organisms. Mortality responses were greater at the higher acclimation temperatures. |
