AN EXPLORATORY VIEW OF HEAVY METAL ANALYSIS IN WATER BODY OF MUSA ESTUARY

Estuaries are marine embayments that are significantly diluted by fresh water. They are often preferred sites for shipping corridors and harbour construction. Because ofshallow depths, slow currents and long residence times for water, they are prone to accumulation of pollutants. Industrial and domestic waste water flows are two mainpollution sources that can affect aquatic life; waste water containing heavy metals can have profound effects on marine life. Current speed and direction, and distance tothe pollution sources are two main parameters of pollutant dispersion and accumulation. The values of heavy metals concentration especially in water bodies could be measured by many different approaches. For gaining a better understanding of these values and the ranges of change in different seas in the world, some studies are mentioned in the following. Many researchers and organizations deal with analysis and monitoring of heavy metals standard levels. Japan International Cooperation Agency (2014) determinedacceptable levels of heavy metals in this area. In addition, Jalali et al. (2015), Safahieh et al. (2013) and Safahieh et al. (2011) measured concentrations of some importantheavy metals using aquatic organisms as bio indicators in Musa estuary at the northwest corner of the Persian Gulf [2-4]. In the majority of their results, the values were morethan standard levels which were issued by WHO; especially, at the end of creeks where residence time of water is long and current speed and direction forcepollutants to be accumulated (Payandeh et al. 2015) [5]. In this study, we try to make a comprehensive data set In this study, we try to make a comprehensive data setof heavy metal concentrations in different parts of an estuary, in order to determine effective parameters and evaluate the level of effectiveness on pollution distribution.We also develop a 2D hydrodynamic model to make a visual analysis of these effective parameters.
