What are the dangers of PCB in transformer oil?

The dangers of PCB in transformer oil include environmental contamination and health risks. Polychlorinated biphenyls (PCBs) are toxic compounds that can leach into soil and water, posing a threat to wildlife and human health. Exposure to PCB in transformer oil can lead to serious health issues, including cancer and immune system damage. Additionally, the presence of PCB in transformer oil can complicate disposal and remediation efforts, increasing operational costs for utilities.
