[EVALUATION OF MIGRATION ABILITY OF POLYCHLORINATED BIPHENYLS IN THE "SOIL-PLANT" AND "SOIL-EARTHWORMS"]

Area of Science:

• Environmental Science
• Toxicology
• Soil Science

Context:

• Assesses polychlorinated biphenyls (PCBs) contamination in Serpukhov city soils.
• Investigates PCB migration dynamics within the soil-earthworm system.
• Evaluates PCB accumulation in terrestrial plants versus soil invertebrates.

Purpose:

• To conduct a hygienic assessment of PCB soil contamination in Serpukhov.
• To determine the bioaccumulation factors of PCBs in earthworms at varying soil contamination levels.
• To compare PCB accumulation in plants and earthworms (Lumbricidae).

Summary:

• Hygienic assessment of soil polychlorinated biphenyls (PCBs) contamination in Serpukhov.
• First investigation into PCB migration in the soil-earthworm system, with calculated bioaccumulation factors.
• Comparative analysis revealed differences in PCB accumulation between plants and earthworms.

Impact:

• Earthworms demonstrate potential as sensitive bio-indicators for monitoring persistent organic pollutant soil contamination.
• Highlights the utility of Lumbricidae worms for detecting even low concentrations of soil contaminants.
• Provides insights into the comparative behavior of PCBs in different soil organisms.
