Abstract

Introduction: MERCURY (Hg) toxicity, its ability to be accumulated in organism’s tissues and its stabilization throughout the natural food chain for a long period has already been proven. MERCURY pollution in the environment could occur via natural physico-chemical reactions on earth crust or due to human activities which cause MERCURY volatilization. Both organic and inorganic components of MERCURY could be found in the nature. In a natural aquatic reservoir, MERCURY initially observed and accumulated in the members of lower trophic levels. Then it will be magnified in the tissues of top consumers. This is called biomagnification. MERCURY causes disorders in respiration and blood circulation, neurotic problems, and declines the reproduction abilities in fish. Fish are known as suitable bio-indicators to detect and track heavy metals, particularly MERCURY in aquatic ecosystems. Accumulated MERCURY has been measured in different tissues of a fish. Muscle tissue, as the most consumed part of a fish body is the most important tissue to determine the level of accumulated MERCURY in fish. Previous studies showed that the level of MERCURY in SANANDAJ GHESHLAGH RESERVOIR was higher than limits established by the World Health Organization and Iranian Standard Center (i.e., 1 mg/L). Field observations verified that intensive agricultural activities and other pollutant sources such as industrial activities were not developed in SANANDAJ GHESHLAGH RESERVOIR watersheds and its upper areas. In addition, previous studies on the geological structures and soil types of the region reported high levels of MERCURY in the bed rock and soil texture. Therefore, it seems SANANDAJ GHESHLAGH RESERVOIR MERCURY pollution has a natural source. The most favorite and consumed fish in the region are Common carp and Silver carp due to their abundance and relatively low price. Therefore, the present study was designed to track and determine and compare the level of total accumulated MERCURY (THg) in MUSCLE TISSUES of Common carp (Cyprinus carpio) and Silver carp (Hypophthalmichtys molitrix) from SANANDAJ GHESHLAGH RESERVOIR during July to December 2009.
