Content of heavy metals in the plants growing in the area of the railway under construction near the Vanino
village (Khabarovsk Territory). T.N. MOTORYKINA (Institute of Water and Ecological Problems, FEB RAS,
Khabarovsk).
The results of the heavy metals content (manganese, copper, zinc, lead, mercury, arsenic and cadmium) in 25 joint vegetable samples collected from the test sites in the village of Vanino at different distances from the railway under construction are presented. The concentration of the investigated elements in the plants of most of the studied sites is within the permissible values and does not disturb the normal functioning of plants. Only at five sites the level of manganese content exceeds the norm, which is due to the peculiarities of shrubs and shrubs of the vacciniaceous plants (Ericaceae) to accumulate this chemical element.
