Accumulation Of Zinc In Liver And Muscle Tissues Of Rainbow Trout (onchorhyncus Mykiss Walbaum 1792)

摘要

In this study, the accumulation levels of zinc in the liver and muscle tissues of rainbow trout (Onchorhyncus mykiss Walbaum 1792) were recorded over a period of 30 days in water solutions of 0 (control), 0.1, 0.5, 1, 5 and 10 mg L~(-1) of zinc chloride (ZnCl_2. There was no mortality at any concentrations of ZnCl_2 during the course of the experiments. The concentrations of zinc in the muscle tissues of rainbow trout were 14.22 (control), 41.05, 45.03, 56.73, 61.44 and 72.53 μg g~(-1) dry weight, exposed to 0 (control), 0.1, 0.5, 1, 5 and 10 mg L~(-1) Zn levels, whereas those in the liver of the fish were 46.53 (control), 155.24, 186.43, 239.51, 261.49, 398.88 μg g~(-1) dry weight, respectively. The accumulation of zinc in the tissue and organs increased with increasing metal concentrations in the medium.
