ABSTRACT.
Using data from monitoring the content of heavy metals in wheat grains in various districts of the
Orenburg region for 2008-2023, the impact of anthropogenic factors on the natural environment was assessed. The values closest to the MPC are: for lead – for the Orenburg region (54% of the MPC), for the Tashlinsky district (72% of
the MPC), for copper – for the Gaysky district (68% of the MPC), for the Orenburg region (62% of the MPC). The
highest rates of increase in the accumulation of heavy metals by wheat are manifested: for zinc – in the Orenburg and
Gaisky districts, for lead – in the Tashlinsky and Orenburg districts, for nickel – in the Orenburg district, for cadmium –
in the Tashlinsky district.
