摘要

Soil pollution by potentially toxic elements (PTEs) and radionuclides, such as 137Cs, poses environmental and health risks, particularly in areas affected by nuclear accidents. This study evaluates PTE and 137Cs concentrations in soil from the Polesie State Radiation and Ecological Reserve in Belarus, a region impacted by the 1986 Chernobyl disaster. Soil samples (0–5 cm and 5–20 cm depths) were analyzed using ICP-OES, a direct mercury analyzer, and gamma spectrometry. While PTE levels were below background thresholds, 137Cs activity in topsoil (up to 117,947 Bq/kg) far exceeded global averages, underscoring the enduring legacy of Chernobyl contamination and the need for continued monitoring and remediation efforts.
