Publication Abstract

Acute Toxicity of Zinc to Some Fishes in High Alkalinity Water Reed, Paula, Dorothy L. Richey, and Donald P. Roseboom, 1980  Illinois State Water Survey, Champaign, IL,  ISWS C-142    Full Text Available

This study documents the acute toxicity effects of varying concentrations of zinc on certain fishes native to Illinois. Fourteen-day bioassays were performed with bluegill fry, channel catfish fingerlings, and largemouth bass fingerlings in waters relatively high in alkalinity and the salts of calcium and magnesium.

The 14-day median tolerance limit at 20 C was 11.0 mg/l soluble zinc for the bluegill, 8.2 mg/l soluble zinc for the channel catfish, and 8.0 mg/l soluble zinc for the largemouth bass. For protection of the fishes investigated, and in compliance with Illinois water pollution regulations, soluble zinc concentrations in Illinois streams having high alkalinity and hardness should not exceed 0.8 mg/1.
