In article results of studying of accumulation of lead are given in vegetative bodies of some one-year ornamental plants in the conditions of Ioshkar-Ola. Changes of the maintenance of Pb in leaves and root system throughout everything ontogenezes at an Callistephus chinensis, Zinnia elegans and Tagetes erecta in various on degree of anthropogenous loading districts of the city are analysed. It is shown that suburban, selitebny and industrial zones are characterized by the unequal content of lead in underground and elevated bodies at the studied plants. Concentration of metal in land and underground spheres at plants was noted by the greatest in an industrial zone. Besides, specific specificity is established by vegetative bodies of Callistephus chinensis, Zinnia elegans and Tagetes erecta. It is noted that the aster Chinese possessed the greatest maintenance of ions of Pb2+ both in assimilatory bodies of a look, and in root system.
