Abstract

The objectives of the present investigation were to study the bioaccumulation of Aldrin, Diazinon and Endrin pesticides in the edible muscle tissues of Tinca tinca, Rutilus frisii kutum, Carassius auratus, Cyprinuscarpio, Silurus glanis and Esox lucius that were caught at various stations in the west, east and centre of the Anzali Wetland and to compare the results with the standards of the World Health Organization (WHO). The concentration of organochlorine pesticide was determined using Gas Chromatography (GC) equipped with an electron capture detector. The concentration of organophosphorus pesticide was determined using Gas Chromatography/Mass Spectrometry (GC/MS). The highest concentration of Diazinon was detected in Esox lucius from the wetland east station (20.25 ppb). Significant differences were not observed in the amounts of Diazinon and Aldrin pesticides in the muscles of fish samples in various stations (P>0/05). The highest amounts of Endrin were observed in the muscle of Cyprinuscarpio from the wetland east and west stations whichwere significantly different compared to that of other fish species (P<0/05). The amount of Aldrin in the Carassius auratus was significantly different compared to that of other fish species (P<0/05). According to the results, the amounts of Aldrin, Diazinon and Endrin were lower than the detection limits of the WHO standards. Therefore, consumers are not at risk from the point of view of food safety.
