ABSTRACT.
The concentration of toxic elements in wheat and soils of the Orenburg region of 28 administrative
districts was studied. The content of carcinogens in the soil of the Orenburg region (in mg/kg) in the Eastern zone is:
lead – 32.20 ± 1.5; cadmium – 0.01 ± ,0001; nickel – 405.8 ± 45.0; chromium – 556 ± 50.0; cobalt – 45.56 ± 5.0; in the
Central zone it is: lead – 47.50 ± 1.5; cadmium – 0.08 ± ,001; nickel – 145.4 ± 50.0; chromium – 352 ± 25.0; cobalt –
22.78 ± 5.0; in the Western zone it is: lead – 58.65 ± 1.5; cadmium – 0.01 ± 0.0001; nickel – 170.2 ± 50.0; chromium –
482 ± 50.0; cobalt – 21.39 ± 5.0. The content of carcinogens in basic food products in the regions of the Orenburg region was distributed as follows. The most common carcinogens in food products for the Eastern region are nickel and
chromium, for the Western region – chromium, lead and cadmium, and for the Central region – all the elements studied
in the course of research.
