In carps exposed during 7 days to the influence of water medium containing copper in concentrations 0.1 and 0.5 mg/L, the content of acid-soluble thiols (AST) in liver decreased about threefold; the contents of malone dialdehyde and acid-insoluble thiols (ALT) were also lowered, but to a lesser degree. At the same time, the level of the metallothionein-like proteins increased. As the effects of 1.0 mg/L copper for 2 days were the diminished contents of common protein and AST, while that of AIT grew. The alterations in the content of thiol compounds may be a sensitive test in studies of copper effects.
