Özet
The present study focused on the uptake and toxicity of Zn in Solea solea. Laboratory studies were performed where metal content, were measured as a response to exposure to nominal concentrations of 0.01, 0.1 and 0.5 mg/L of zinc salts (ZnCl2) for 60 days. The levels of Zn accumulated in edible tissues and gills of S. solea correlated well to exposure concentrations and the greater the uptake. Significant accumulations were observed in muscle Zn levels at the 0.5 mg/L treatment in comparison to controls (p<0.05) with maximum average of 3.99 +/- 0.2 mg Zn/g wet weight. Also, there were significant increases in gill Zn concentrations at two experimental groups compared to the controls (p<0.05) with maximum averages of 82.59 +/- 6.6 and 84.48 +/- 7.2 mg Zn/g gill wet wt. at 0.1 and 0.5 mg/L treatments, respectively. No significant changes were observed in visceral organ Zn levels after 60 days of ZnCl2 exposures. Mortality increased with increase in concentration of Zn on S. solea and time of exposure.
