Background. To study features of cereal grasses pollen collected in region were the enterprise that is in charge
of destruction of the chemical weapons is placed - Gorniy, Saratov region.
Materials and methods. Object of the research was pollen of cereal grasses collected in regions, differed by the
ecological characteristics: object for destruction of chemical weapon of Gorniy of the Saratov region (investigated
region), Privolzhsky area of the Ivanovo area (ecologically favorable region) and near to а motorway, Istrinsky
area of Moscow Region (ecologically unfavorable region). Definition of the maintenance of heavy metals in pollen
of grasses was carried out by the method of invertion voltamperometry, by percentage of sprouted pollen grains
and the morphological characteristics of pollen grains by microscopy.
Results. In samples of pollen collected within object for destruction of the chemical weapon of Gorniy, the
maintenance of lead, mercury, zinc and cadmium, in comparison with non-polluting area, and with average
values across the Russian Federation, thus lead almost ten times above, in comparison with average values of
the maintenance in plants across the Russian Federation is authentically increased. The morphological changes
of pollen more expressed in ecologically adverse region are revealed: the quantity of abortive pollen grains
near to а motorway was above more than ten times, and, within the enterprise for the object for destruction of
the chemical weapon of Gorniy, almost in 3 times, in comparison with non-polluting region. It is established
that along with heavy metals (lead and zinc) which are а part of the list of the harmful substances containing
in emissions in atmosphere of the enterprise for the object for destruction of the chemical weapon of Gorniy,
the increasing of mercury and cadmium levels which are absent in а production cycle is revealed and can t be
connected with enterprise functioning. Possibly other sources of pollution render.on the mercury and cadmium
maintenance .
Conclusion. Thus, in experiments it has been shown that pollen of plants possesses considerable sorbtion capacity
for the heavy render metals which are а part of harmful production factors which change bioindicator properties
of plant pollen and could form hypersensitivity.
