ABSTRACT
Introduction:
Background. Cadmium and lead are classified as toxic metals. Toxicity is attributed to the adverse effect on the human body, and therefore the content of these elements is analyzed in the environment and in food products. Studies conducted by many researchers indicate that more of cadmium and lead accumulate in products of plant origin, however, food products of animal origin are also not free from these compounds. The aim of this study was to determine the content of cadmium and lead in drinking milk originating from four selected milk producers from two different regions.
Material and Methods:
A total of 28 milk samples were tested. The tested material was mineralized dry. To determine the content of the analyzed elements the Flame Atomic Absorption Spectrometry method was used. There were no significant differences in the content of heavy metals in the analyzed samples of milk.
Results:
None of the samples revealed the exceedance of the highest permissible level of these elements.
Conclusions:
Cadmium and lead content in tested drinking milk does not pose a threat to human health
