This study was conducted at the request of the Velsicol Chemical Corporation to determine the static acute toxicity of Sodium Acetate to be the bluegill sunfish. The test was performed at Union Carbide Environmental Services' (UCES) toxicity laboratory in Tarrytown, New York. Sodium Acetate is a white water soluble powder. The bluegill sunfish, Lepomis macrochirus Rafinesque, is a warm water fish usually found in ponds, lakes and sluggish streams with bottoms of sand, gravel or mud. They feed on a variety of aquatic organisms including fish eggs, small fish, snails, insects and amphipods. Bluegills prefer temperatures above 20 degrees C and can tolerate a wide pH range. Because of their wide geographic distribution, temperature requirements and importance as food web organisms, the bluegill has been recommended by the Committee on Methods for Toxicity Tests with Aquatic Organisms (1975) as a bioassay organism.
