Assessment of Potentially Toxic Element Contamination in the Philippi Peatland, Eastern Macedonia, Greece

Researchers found that the Philippi peatland, one of the deepest in the world and a significant ecological site, exhibits low to moderate contamination by potentially toxic elements (PTEs) like selenium (Se), lead (Pb), and zinc (Zn). While most PTEs showed minimal environmental risk, Se and Pb were notably higher in certain areas, indicating localized heavy contamination. The study analyzed 16 sites using soil and corn grain samples, revealing high bioaccumulation factors for Cu, Zn, and Se, suggesting these elements are more mobile and readily absorbed by plants. Soil conditions were neutral to slightly alkaline, with organic matter ranging from 93 to 557 g/kg. These findings highlight the need for targeted monitoring of PTEs in this UNESCO-listed site to mitigate potential ecological risks.
