Exposure to heavy metals is an important problem of environmental toxicology. Most of these metals are toxic to humans, animals and plants. Anthropogenic activities are the major sources of heavy metals redistribution. Man, being at the top of the food chain, is at great risk of suffering from health hazards associated with toxic metals because of bioaccumulation The aim of this study was the evaluation of the heavy metals contents in the food of

Human hair can be used effectively for biological monitoring of the highest priority toxic trace metals. The aim of this study was the evaluation of the heavy metals contents in the hair and the urine collected from children (15 –18 years old) living in the Iassy area, from Romania. Trace elements concentrations were analyzed by atomic absorption spectrophotometry, using a Carl Zeiss Jena, Model AAS-1N, with flame air-acethylene. In all analysed

Ever since humans have become aware that health is inseparably linked to an intact and healthy environment, the control and reduction of pollution have become the focus of worldwide concern. The studies on heavy metals concentrations in human placenta and human milk have been performed, as a continuation of the research conserning heavy metals concentrations in biological and in food samples by atomic absorption spectrophotometry method. The aim

Heavy metals toxicity is the result of their interactions with the enzymatic systems from the animal cells or some constituents of cells membranes. The interactions of heavy metals with usual elements from diet (Pb, Cd) have an important role in acute and chronic toxicity. Population can be contaminated with heavy metals by ingestion of contaminated or polluted food or water. The concentration of heavy metals in food products is varied, depending

The extensive use of pesticides in agriculture can entail risks for environment and non-target organisms. Hence the need to assess the nature and degree of the risk and at the same time to take preventive measures aimed at minimizing possible damages. The aim of the present study was to investigate the pesticide residues in food and the human body (maternal, young) in the Eastern Romania area, between 1996 and 1997. The organochlorine pesticide residues
