Heavy metals in agricultural crops of Rostov region through the example of soft wheat (Triticum aestivum)

In recent decades, the problem of an annually increasing level of anthropogenic impact on the environment has become increasingly important. One of the most dangerous pollutants entering the environment from industrial emissions is heavy metals. This type of pollutant is not subject to biodegradation over time, due to which they accumulate in environmental objects in dangerous concentrations. The resistance of soft wheat (Triticum aestivum) of the Myatlikovy family (Poaceae) to aerotechnogenic pollution in the soil and climatic conditions of southern Russia was studied. The content of heavy metals in this culture growing in the impact zone of Novocherskasskaya power plant is analyzed. The pollution with Pb, Zn, Ni and Cd was established. The average and close correlation was established between the total content and the content of mobile forms of HM in the soil and their content in wheat plants. For the studied plants, the accumulation coefficient (AC) and distribution coefficient (DC) of TM were calculated. The values of the coefficients showed a significant accumulation of elements by plants from the soil, as well as their translocation from the root system to the aboveground part.

Automated summary

In recent decades, the increasing anthropogenic impact on the environment has made the issue of industrial heavy metal pollutants more important. The study in southern Russia found that soft wheat has some resistance to air pollution in the soil. Heavy metals accumulate and transfer significantly from the soil to the wheat plants.
