Accumulation of Heavy Metals (Lead and Zinc) in the Liver of Some Edible Fishes in Zayandeh-rood

H. Maaboodi, S. Jamili and H. Maddani

The aim of the study is measuring and studying the amount and variation of some important heavy metal on fish body. Zayande-rood flows from origin in Chahar-Mahal-Bakhtyari to the East of Iran and endes in Gavkhooni swamp in Isfahan province. Waste waters from farming, homes and industry are responsible for its pollution with heavy metals which can be absorbed from the liver of fishes. Therefore a study on environmental varieties is important. In order to determine the amount of lead and zinc in the liver of fishes, 5 stations have been organized as follow: Zarinshahr, Nekooabad, Falavarjan, Wahid, Choom. Edible fishes belong to the Cyprinidae group and Carrassius, C. aculeata, C. damasciana, C. carpio species. In order to asses the amount of lead and zinc, the liver tissue of fishes separates, burns, digests their ashes then the amount of heavy metal is calculated. The A.A.S. average of lsead was 3.13±0.9 mg kg-1 dry weight, p<0.05 and zinc was 146.5±36.9, p>0.05. The zinc level is high but lead is normal. There is a high level of zinc in Zayandehrood. These results support with other studies by other researchers. A high level of zinc could cause metabolic disorders and a detoxification process could create many clinical damages in human.
