Abstract :

Study of White Leg Shrimp regarding Heavy Metals and Risk Assessment for Consumption. Study of White Leg Shrimp (Litoppenaeus Vannamei) of Shrimp farming complex in, Arak Province, with the Perspective of Contamination by Heavy Metals and Risk Evaluation for Consumer. For this purpose, 30 samples were analyzed by atomic absorption after drying and chemical digestion. The data were analyzed using SPSS software. The different heavy metals were identified in shrimp samples, including arsenic (As), cadmium (Cd), mercury (Hg), lead (Pb), iron (Fe), copper (Cu), cobalt (Co), chromium (Cr), manganese (Mn), molybdenum (Mo), nickel (Ni) , tin (Sn) and zinc (Zn). The average amount of As, Cd Hg and Pb was 0.11-0.08, 0.01, 0.01 and 0.38-0.14 mg/kg, respectively. Sn and Ni had a lower average than other metals. Among the essential heavy metals, Fe and Cu were the highest level, followed Zn and Mn. Co, Cr and Mo were the lowest level. A significant difference was reported between different sites in regarding Zn (P<0.05). The concentration of all heavy metals was according to the standard limit (FAO/WHO). Continuous and daily consumption of this product for different age groups is not safe in terms of As and there is a risk, but it is safe for other metals. It is possible to reduce the dangerous effects of heavy metals by monitoring, regularly examining and evaluating these mineral pollutants.
