The investigation of some heavy metal accumulations and their toxicity effects on the crayfish (A. leptodactylus ESCH., 1823) living in the lakes of West Anatolia (Apolyont, Manyas, Egirdir, Civril, and Marmara)
BIOSIS COPYRIGHT: BIOL ABS. The levels and seasonal and locality changes of heavy metal (Fe, Zn, Cu, Pb, Mn, Cd, Hgt) concentrations in crayfish, A. leptodactylus, taken from the lakes of West Anatolia have been investigated. According to our present data, heavy metals in the muscles of crayfish, A. leptodactylus, varied as follows: copper (Cu), 3.40-19.300 mug/g: iron (Fe), 5.493-40.364 mug/g; zinc (Zn), 10.300-37.526 mug/g; cadmium (Cd), 0.148-1.083 mug/g; manganese (Mn), 0.443-4.785 mug/g; lead (Pb), 0.376-3.198 mug/g; and mercury (Hgt) 0.006-1.713 mug/g; (wet weight basis). In the carapace they were: (cu), 7.022-24.927 mug/g; iron (Fe), 42.580-348.225 mug/g; zinc (Zn), 8.259-42.445 mug/g; lead (Pb), 3.731-14.810 mug/g; cadmium (Cd), 0.51 0-4.975 mug/g; manganese (Mn), 14.378-160.347 mug/g; and mercury (Hgt) 0.003-1.105 mug/g; (wet weight basis). In the carapace they were: copper (Cu), 7.022-24.927 mug/g; iron (Fe), 42.580-348.225 mug/g; zinc (Zn), 8.259-42.445 mug/g; lead (Pb), 3.731-14.810 mu
