Abstract :Gammarus pulex insert ignore into journalissuearticles values(L.); collected from clean sites around Kabakli pond insert ignore into journalissuearticles values(Diyarbakır); was acclimatized at 15°C for 10 days. The individuals were placed in 1lt. vessels and exposed to Cu ++ concentrations of 0.05, 0.08, 0.10, 0.15, 0.20, 0.30 and 0.50 ppm to determine both 24, 48, 72 and 96 h LC50 values and Cu ++ accumulation over 96h. LC 50 values at 24, 48, 72 and 96 h were calculated to be 0.2, 0.17, 0.12 and 0.1 ppm, respectively. Acute copper accumulation in gammarids exposed to various copper concentrations over 96 h was determined using an atomic absorption spectrophotometer. An equation of logY=1.523+0.078logx, r=0.976 was obtained from the relationship between the copper concentration of the surrounding water insert ignore into journalissuearticles values(X); and the body copper accumulation insert ignore into journalissuearticles values(Y); in G. pulex. This relatonship was found to be statistically significant insert ignore into journalissuearticles values(P
