Persistent organic pollutants of the Baikal Pulp and Paper Mill Solzan landfill
Abstract
The results from studies of the Solzan BPPM landfill for the contents of persistent organic pollutants in sludge-lignin, ash from 10 storage maps, soils of the landfill and its surrounding territories are presented. The sampling was carried out in August-October 2024. The analysis was performed at the Vinogradov Institute of Geochemistry SB RAS using the GC/MS method on the Kristall-5000. The maximum concentrations were found for polychlorinated biphenyls (PCB) (up to 3.900 mkgƩ32PCB/kg of soil and up to 481 mkgƩ32PCB/kg of sludge-lignin). For the first time, such a powerful source of persistent organic pollutants has been discovered in the central ecological zone of the Baikal Natural Territory.
