Abstract :
Contamination of soils and plants with heavy metals is a serious and growing problem that can cause chronic and underlying diseases by entering the food chain. The aim of this study was to investigate the exposure of water, soil and food sources to heavy metals such as zinc, copper, cadmium and lead and the possible risk of their consumption . Methods: This study was conducted by reviewing articles on soil and water pollution in Iran and using Internet sites.Results: According to different studies, the difference between the mean concentrations of copper, zinc, lead and cadmium between soil, water and different nutrients was significant (P> 0.001 A. The studies showed Contamination of water and soil, followed by the resulting food chain with heavy metals zinc, copper, cadmium and lead, was significantly associated with the occurrence of underlying diseases in individuals and the risk of cancer for each element is less. It was obtained from one and the consumption of heavy metals was less than the tolerable daily consumption. Conclusion: The results of this study showed that the major part of the accumulation of heavy metals is in vegetables. Which will eventually lead to the entry of these elements into the human food chain. Therefore, great attention should be paid to the consumption of vegetables, especially vegetables grown around industrial areas, and soil contamination with heavy metals can cause long-term entry. These compounds are inhaled into the human body and cause chronic underlying diseases. However, the amount of pollutants, type, and geographical location of the area are also important.
