Heavy metals and radon content in spring water of Kosovo

Abstract

Paper presents results of researches carried out on various locations and immediate vicinity of mining and industrial activities of the northern and south-eastern part of Kosovo. Concentrations of As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn, Rn-222, as well as temperature and pH values of natural spring water were measured at 15 measuring sites (that belong to Zvečan, Leposavić and Novo Brdo municipalities), in April–May and September–October 2019. The quantification of heavy metals’ content was performed by applying ICP-OES method. In analysed samples a high content of As, Pb, Fe and Ni was found. Carcinogenic and non-carcinogenic risks due to the content of heavy metals in water were evaluated. Concentration of radon in water was measured by the alpha spectrometric method, and measured values range in the interval from 0.34 ± 0.12 to 341 ± 35 Bq/L. The yearly doses of inhalation and ingestion were determined for the measured concentrations of radon. Mutual correlation by the Pearson correlation coefficient, principal component analysis, cluster analysis and spatial distribution analysis of the researched parameters of sampled water were done. The most expressed mutual dependence of some heavy metals leads to the conclusion that they have the same anthropogenic origin.

Pilot groundwater radon mapping and the assessment of health risk from heavy metals in drinking water of southwest, Nigeria

“…Radon and heavy metals are considered major pollutants which pose a serious threat to water quality. These two water pollutants are well known for their carcinogenic potentials (Markovi c et al, 2020;Ahmad et al, 2020). Due to the rapid increase in world population, exploitation of water resources has also increased to cope with the rising demand from domestic usage, particularly for drinking purposes (Díaz-Alcaide and Martínez-Santos, 2019).…”

Evaluation of Water Quality and Its Potential Threats Along River Drini Bardh Using Analytical Instrumental Techniques

“…The accumulation of heavy metals in excess of environmental standards can result in environmental and human health problems [3][4]. Characterization of metals in rivers, lakes, fish, and sediments has been a prominent focus of environmental research in recent decades [5].Bottom sediments in aquatic habitats provide insight into the processes and mechanisms that occur in aquatic ecosystems [6][7]. Hydrological cycles, physicalchemical processes and intricate spatiotemporal variation all contribute to the remobilization of heavy…”

“…Sediments (silt and clay) containing ecotoxic heavy metals and other inorganic and organic chemicals are critical for investigating water pollution. Hence, they require multidisciplinary research to better understand various processes and the geochemical cycles of various trace elements [1][2][3][4][5][6][7][8].…”
