Abstract

This study was carried out in 2004 with the purpose of determining the source and quantity of pollution in the livers of fishes of Khorramabad WATERSHED by some pollutant elements. Fourteen environmental elements were distinguished in the liver of various species of fishes that have been sampled by electrofishing method from 15 sites within this WATERSHED by using atomic absorption spectrometer and flame photometer. The most important sampling sites were local mines, agricultural lands, mixed zones and urban/rural residential areas. The elements of lithium and silver were seen in none of the analyzed fish samples. The minimum concentration of TRACE ELEMENTS in fish liver of the WATERSHED belongs to vanadium and the maximum concentration belongs to iron. High concentration of zinc in liver samples is because of the fishes need to this minor nutritional element especially in early days of growth. Poor concentration of mercury and arsenic in fish liver tissue is the result of agricultural poisons and drainage waters of marginal farms entering the surface waters of the study unit. The TRACE ELEMENTS concentration in fish liver is positively related with the concentration of these elements in the food, water and sediments consumed by the fish, and with the rate of BIOACCUMULATION.
