Abstract
Information on the peculiarities of contaminant elements accumulation by cultivated and wild-growing plants in the zone of influence of Belinvesttorg-Splav LLC (Beloozersk), whose emissions into the air contain hazardous pollutants, including (heavy metals) HM, is presented. Analysis of the degree of elements accumulation by agricultural plants was carried out in comparison with subregional background values and permissible levels of veterinary and sanitary rules for ensuring the safety of feed, feed additives and raw materials for the production of mixed feed. As the main criterion for assessing the degree of contamination of HM leaves of wild plants, indicators of their background concentrations, as well as world averages, were used.
 The established aero lead pollution of cultivated agricultural plants in the sanitary protection zone of Belinvesttorg-
 Splav LLC and in the adjacent lands repeatedly exceeds the background and sanitary-hygienic values. Among the wild
 plant species studied the most sensitive indicators of aerogenic pollution are: among the woody plants – common pine
 (needles), in the group of bushes and shrubs – white mistletoe and common raspberry, among herbaceous plants – dioica
 nettle. Research results testify to the necessity of sanitary protection zone extension for Belinvesttorg-Splav LLC at least
 up to 1000 m (especially – according to the rose of prevailing winds) and cessation of agricultural activities within it.
