 Abstract

The objective of this study was to determine the contents of heavy metals in agricultural land of the Obiliq municipality, Kosovo. The study was carried out during 2015. Sampling was administered in agricultural lands of Obiliq area, which was cultivated with Capsicum Annum. Elements analyzed included: As, Cr, Ni, Pb and Zn. Heavy metals were analyzed using Atomic Absorber Spectrophotometry (AAS) at Technology Transfer Center in Fushe-Kruje. The analyses have demonstrated lower values of As with a minimum and maximum of 39.88 mg/kg and 53.43 respectively and higher values of Zn with a minimum of 107.29 and a maximum of 736.35 mg/kg. The average contents of heavy metals has been esablished in this order: Zn>Cr>Ni>Pb>As. Considering the perennial cultivation with Capsicum Annum of these lands and the continuing impact of industrial activities in the area, especially in Obiliq, it is necessary to track and analyze the content of heavy metals and the quality of vegetables consumed by the population.
