Definition of Water Quality Requirements for the Protection of Aquatic Life. 



This project consists of: (1) Basic studies on the toxicology and environ- 

 mental requirements of aquatic life; (2) development of procedures for esti- 

 mating the effects of long-time exposures by means of short-term bio-assays; 

 (3) relationship of pH, alkalinity, hardness, and other water quality character- 

 istics to the toxicity of metals and other chemicals; and (4) studies of the 

 toxicity of selected industrial effluents and other materials to fishes.
