Heavy metals content in the selected soils and fruits in Montenegro and estimation of their daily intake through fruits consumption

Abstract

Levels of Pb, Ni, Cr and Cd, in soil and fruits (Rubus idaeus - raspberry and Vaccinium myrtilus - blueberry ) at 26 locations in Montenegro were examined. Heavy metals content in the samples was determined by AAS method. In the soils, the content of heavy metals was below pollution threshold, except at one location (Kolašin region). In the berries, heavy metals content was mostly within normal range for plants and guideline values for fruits. The calculated daily intakes of metals through selected fruits consumption are found to be below the recommended tolerable daily intakes proposed by FAO/WHO.

U radu je ispitivan sadržaj: Pb, Ni, Cr i Cd u zemljištu i plodovima borovnice (Vaccinium myrtilus) i maline (Rubus idaeus) sa 26 lokacija u Crnoj Gori. Sadržaj teških metala u sakupljenim uzorcima određen je AAS metodom. Sadržaj teških metala u zemljištu bio je ispod praga kontaminacije, izuzev na lokaciji Kolašin. Sadržaj teških metala u plodovima borovnice i maline nalazio se u intervalu normalnih vrednosti za biljke, kao i u okviru predloženih granica za bobičasto voće. Procenjeno je da se dnevni unos teških metala putem konzumiranja plodova nalazi ispod vrednosti dnevnog unosa koji je preporučen kao prihvatljiv od strane FAO/WHO.
