An attempt was made to estimate the dimension of direct toxic effects of exposure to Cd on the basis of researches on reproductive parameters in small mammals in natural populations ( on the example of red-backed vole) inhabiting localities of large-scale non-ferrous metal plants and comparison of results obtained with outcome of toxicological experiments ( chronic exposure of female rats to Cd) ). It was expected that at the existing pollution levels, embryonic losses caused by direct toxic
