Sublethal effects of chlorinated phenols and resin acids on rainbow trout (Salmo gairdneri)

The aim of this work was to study the effects of toxic compounds in pulp and paper mill effluents on fish (Salmo gairdneri ) and fish physiology. This was done by studying the accumulation of 2,4-dichlorophenol, 2,4,6-trichlorophenol and dehydroabietic acid in fish and the physiological responses of...

Description
Summary:The aim of this work was to study the effects of toxic compounds in pulp and paper mill effluents on fish (Salmo gairdneri ) and fish physiology. This was done by studying the accumulation of 2,4-dichlorophenol, 2,4,6-trichlorophenol and dehydroabietic acid in fish and the physiological responses of fish to this accumulation. Tests were performed at two concentrations, 5 mu g/l and 50 mu g/l, and during the exposure period mainly hematological parameters were measured in the fish. The toxicants tested affected most of the parameters analysed (blood hematocrit, leucocrit, hemoglobin, mean cellular hemoglobin count, plasma glucose, lactate, liver glycogen).
