Abstract
The purpose of this paper is to find out the nickel level in the serpentine multi-floral-honey obtained from the honeybeeswith higher nickel concentration than the non-serpentine flora. The average value of Ni concentration in the aerial part of examined flora samples comprised of 10 different plant species resulted to be 336mgkg-1. The honey was collected from 1 apiary three years in the row,which is situated in serpentine area of south-eastern part of Kosovo-Rezhance and from 3 other apiaries from non-serpentinearea. Obtained results have revealed higher concentration of nickel in the serpentine multi-floralhoneythan those in the non-serpentine honey.
The average Ni level in the serpentine multi-floral honey was 3.71mg.kg-1, with the highest concentration of 3.96mgkg-1. Whereas the average levels of Ni in the non-serpentine flora was1.66 mg.kg-1.with the highest reading of1.92 mgkg-1.
In conclusion, the entire amount of nickel in the honey comes either from nectar collected by honey bees in the Ni accumulative and hyper-accumulative serpentine flora or by dust coming from serpentine soils, which is abundant on Ni content.
