The Evaluation in Different Temperature of Acute Toxic Effect of Cadmium on Gammarus pulex (Freshwater Amphipoda)

Abstract

In this study, the LC50 values of the cadmium (Cd) toxicity on the Gammarus pulex were investigated. In this study, it was aimed to determine the change of LC50 values of Cd at G. pulex at 10, 14 and 18°C.The lethal concentration (LC50) values for G. pulex which were exposed to various Cd concentrations for 96 hours were determined at different temperatures as 10, 14 and 18°C. LC50 values obtained by probit analysis were found to be; 51.79 ± 1.2 µg L-1 for 10°C, 47.67 ± 0.6 µg L-1 for 14°C and 33.93 ± 0.6 µg L-1 for 18°C. LC50 values were found to decrease due to the increase in temperature.
