Abstract

Introduction: HEAVY METALS are originated from natural or anthropogenic sources. Mining activity, fuel combustion, urban discharge, pesticides, agricultural and industrial activities are considered as the m ain anthropogenic sources of the metals. Generally, more than 90% of the toxic metals load in aquatic systems is bound on solid phase of the aquatic systems such as suspended matter and sediment. Thus, assessment of HEAVY METALS pollution in aquatic sediment is a critical issue that has been studied by many researchers. Anzali International Wetland was registered in Ramsar Convention in 1975 (Ramsar site #40, Wetlands International Site Reference No.: 2IR005). It is located in Guilan Province (between 48°45' and 49°42'E longitude and 36°55' to 37 32'N) and covers 192 Km2 that is considered as the main freshwater coastal wetlands in southern part of the Caspian Sea. Its catchment area with prevalent agricultural activities is about 3610 Km2. Moreover, presence of 41 major factories such as wood and paper mill companies, food industries, metal and related industries, plastics and tires, textile and electrical machines are samples of anthropogenic sources in the study area. In the present study forty one surface sediment samples in January 2011 were collected from Anzali International Wetland to assess metals pollution state and sediment quality zonation. Moreover, metals pollution assessments in the study area were conducted using different existing indices, multivariate analysis approach and GIS tools.
