The straw of cereals contained much more heavy metals than the grain. In potato tubers there were more heavy metals in the peel than in the flesh, independently of the distance of sampling, while in mangolds and parsley more heavy metals were found in the leaves than in the roots. The greatest pollution by heavy metals, especially Pb and Cd, was ascertained in leaf vegetables as well as in leaves of root vegetables. In leaves of vegetables thoroughly washed with warm water after sampling, the content of heavy metals was smaller by 30-95 percent as compared with the un-washed ones. This indicates that the plants were chiefly polluted by heavy metals as a result of sedimentation of dusts containing the investigated elements
