ABSTRACT
We used a mercury analyzer to determine total mercury (Hg) content in samples of plants and animal origin raw materials collected from an area impacted by the copper industry (Legnica-Głogów Copper District). In 2014 and 2015 we analyzed samples of wheat (grain); potatoes (tuber); dry grass (hay); cow milk, hair, and blood; and poultry liver, muscles, and eggs from 14 villages. Generally, no increased Hg concentrations in the analyzed samples were found. There were no significant differences between the examined years. The highest content of Hg was found in grass (hay) and cow’s hair. There was a many-fold decrease of mercury concentrations in cereals, cow milk, and poultry (eggs, muscles, liver) in comparison to previous studies (2002-07), which indirectly proves that the environmental efforts led by local authorities and industry have been effective.
