وضعیت آلودگی مواد غذایی با منشا دامی و آبزیان به فلزات سنگین در کشور

Status of heavy metal contamination of foods with animal and aquatic animal origin in Iran The status of heavy metals contamination in foods with animal and aquatic animal origin was studied. In spite of limited studies about foods (except fish and edible marine foods), data shows low contamination of milk with lead but relatively high level of cadmium in this product. Iron contamination was found in high level in milk in the industrial areas. Concentrations of lead and copper were found relatively high in some imported infant milk powder. In some fishing areas in Khazar, the concentrations of lead and cadmium were higher than international standards. The same situation is seen in south sea’s fishery products for lead ,cadmium and nickel. In a survey in 2005, mercury level was found higher than permitted level in white fish hunted from central Khazar’s fishing area. Shrimp was found relatively free and safe for heavy metal contamination. Other marine foods such as oyster contamination with nickel and vanadium were observed. The sole study about red meat shows lead contamination in low percentage of studied samples.
