摘要：This study was performed in spring 2008 in order to determinate of Cd and Pb accumulation in gills, kidney, skin tissues and muscles of Chalcalburnus chalcoides in Anzali Port in the South west of Caspian Sea within 10 km2 zone. The samples were collected from 12 stations, biometric measurements had been taken, thereafter, tissues were separated and digested chemically and then it were analyzed by Flame Atomic Absorption Spectrophotometer. Pearson correlation of metalâs concentration in studied tissues with the weight and forked length of fish showed non significant relationship between weight and length (pâ¥0.05) and results showed that smaller fish have higher concentration of Cd and Pb than larger ones. Maximum concentrations of Cd and Pb were recorded in gills (0.94 and 8.33 ppm) while minimum concentrations were recorded in muscles (0.02 and 0.12 ppm). Results show that Cd and Pb were accumulated in descending order in gills>skin>kidney>muscles. The level of metals was compared with (WHO, 1993) standard and it was resulted that Cd in gills and Pb in all tissues were significant difference at (p<0.05) levels.
