For study were used simultaneous tests of phytotoxicity and mutagenicity (Vicia sativa, Vicia faba test, Tradescantia paludosa 03 test, Tradescantia 4430 test), phytotoxic and cytogenetic tests in situ and phytotoxic and genotoxic analyses of pollen grains. Although the dose of some samples was relatively high (322 kBq/kg 137Cs) there were not observed any significant impact on the biological level of tested wild plant species in situ. These results were confirmed by means of standard laboratory plants in vivo.
