Assessment of Heavy Metals in Potato (Solanum tuberosum L.) and Onion (Allium cepa L.) cultivated in Vushtrri area – Kosovo

The consumption of vegetables cross‐contaminated with heavy metals carries a considerable risk for humans (especially for children and pregnant women) and these dietary implications are discussed while European Food Safety Authority has been urged to look into this matter of concern. This project aims to research the degree of pollution with heavy metals in vegetable products such as potatoes and onions with toxic elements as Arsen, Leaden, Cadium, Chromium, and Nikel. The results showed that the element. As was not identified at all, then the element Pb varies from (0.002-0.035 ppm), the element Cadmium from (0.001- 0.030 ppm), the element Chromium (0.060-0.638 ppm), and the element Ni, (0.315-4.512 ppm). Potato and Onion samples were treated in the UBT Laboratory premises, and then the reading of the toxic elements of the samples was done with the ICP (plasmatic copular induction). technique. From the obtained results we can conclude that the concentrations of Pb, Cd, As, Cr, and Ni does not exceed the standards considered as a risk to human health
