title: Chemical composition of wild boar meat and relationship between age and bioaccumulation of heavy metals in muscle and liver tissue.
abstract: This study determined the accumulation of selected heavy metals (Pb, Cd, Hg and As) in tissues of wild boar. The tested animals were divided into three age groups, which allowed analysis of the statistical/mathematical relationship between their age and contamination of their tissues. For determination of heavy metal content, samples were taken from the longissimus muscle of the back and from the tail lobe of the liver. It has been stated that, in wild boar, accumulation of lead and cadmium in muscle and liver increases with age. However, statistical differences were found most frequently between the youngest and oldest animal groups only. Moreover, in no single case, was the maximum permissible level exceeded in muscle for lead, cadmium or mercury, and arsenic was not detected above 0.001 mg/kg. In the >3 year group, the maximum permissible level of cadmium (0.5 mg/kg) was exceeded in two liver samples.
