Animals living in the contaminated areas are exposed to elevated concentrations of risk elements. Příbramsko is one of most contaminated sites in Czech Republic. This area is loaded with sources of geological and metallurgical industry influence resulting in extremely high Pb, Cd, and Zn contents in soil. We analyzed eighteen subjects trapped on selected locations, belonging to the species Apodemus sylvaticus and Microtus arvalis. By differential pulse voltammetry and modified Brdička reaction, concentrations of metallothionein (MT) in their livers were measured. The influence of field sample treatment on resulting voltammetric record has been demonstrated. Differences of MT concentrations were found between species and among places of trapping.
