Description

The aim of this research was to evaluate the possible contamination by heavy metals of milk from cows in Macedonia. The concentrations of heavy metals were determined in cow milk from the different farms, at three city (Kumanovo, Tetovo, Gotivar)in Macedonia. Each sample, homogenized and powdered, was mineralized in a microwave oven.

Quantitative analyses of Cd, Cr, Cu and Pb were performed using an atomic absorption spectrophotometer with graphite furnace; As was analyzed by hot vapor generation technique and Zn with the flame method.

The concentration of many metals is low (<0.1 mg/kg) such as: As,Co, Cd, Cr, Cu,Fe, Pb, and Zn.
