Significant environmental concerns are raised by heavy metal pollution in soils, particularly in areas like South Kazakhstan where hazardous materials have accumulated as a result of human activities including mining, industry, and agriculture. This paper presents theoretical and experimental findings regarding the phytoremediation potential of sowing peas (Pisum sativum) in the grey soils of South Kazakhstan. Special attention is paid to the determination of gross concentrations of various forms of copper, nickel, and cobalt in the initial and remediated soils. The methodology basis for the study were chemical phase analysis, atomic absorption spectrometry, and X-ray electron microscopy to assess heavy metal levels in soils and plant samples. It was established that in the arid climate of Southern Kazakhstan, the upper layers of the soil up to 40 cm contain the highest concentration of heavy metal ions. The findings of the study will allow predicting the effectiveness of phytoremediation measures. The study suggests that sowing peas have potential for phytoremediation due to their ability to accumulate heavy metals in their root systems and biomass. It highlights the potential of phytoextraction techniques, which involve growing metal-accumulating plants in polluted soils and processing the harvested biomass to recover absorbed metals.
