Dependences between the age and the level of bioaccumulation of heavy metals in tissues and the chemical composition of wild boars' meat

International audience; The purpose of the conducted tests was to determine the level of accumulation of selected heavy metals (Pb, Cd, Hg, As) in tissues of wild boars. The tested animals were divided into 3 age groups, which allowed the analysis of statistical-mathematical dependences between the age of animals and contamination of their tissues. The research material for determining the content of heavy metals was taken from the longissimus muscle of back, and samples of liver from the tail lobe. It was stated that accumulation of lead and cadmium in muscles and in liver increased together with the age of wild boars. However, most frequently the statistically essential differences were found only between the group of the youngest and oldest animals. Moreover in no single case was exceeded the maximum permissible level in meat, both for the contents of lead, cadmium as well as mercury. In the tested samples of tissues of wild boars there were also not stated the presence of arsenic above 0.001 mg/kg. In the group of animals above 3 years in the case of two samples the maximum permissible level of cadmium in liver (0.5 mg/kg) was exceeded.
