From the Guidelines
The best way to manage Polychlorinated Biphenyls (PCBs) is to minimize exposure and focus on reducing environmental and occupational exposure, as PCBs have been classified as a Group 1 carcinogen by the IARC, indicating sufficient evidence of cancer in humans 1.
Key Considerations
- PCBs have been linked to various types of cancer, including malignant melanoma, and have been shown to alter receptor-mediated mechanisms and induce oxidative stress and DNA damage 1.
- The management of PCBs should prioritize reducing exposure, particularly in occupational settings, and promoting environmental remediation efforts.
- Studies have suggested that PCBs may have multiple mechanisms of carcinogenesis, including induction of cell proliferation, decreased apoptosis, and oxidative DNA damage 1.
Recommendations
- Minimize exposure to PCBs in occupational settings by implementing proper safety protocols and personal protective equipment (PPE) 1.
- Promote environmental remediation efforts to reduce PCB contamination in soil, water, and air.
- Support research into the mechanisms of PCB carcinogenesis and the development of effective strategies for reducing exposure and mitigating health risks.
- Conduct regular health monitoring and screening for individuals exposed to PCBs, particularly in high-risk occupational settings 1.

From the Research
Management of PCB
To manage Polychlorinated Biphenyls (PCBs), it is essential to understand their effects on human health and the environment. The following points highlight the key aspects of PCB management:
- Exposure routes: PCBs are fat-soluble substances, and everyone is exposed to them through ingesting animal fats, inhalation, or dermal contact 2.
- Health effects: Exposure to PCBs can suppress the immune system, increase the risk of acquiring several human diseases, and alter thyroid and reproductive function in both males and females 2, 3.
- Reduction methods: There is limited evidence on effective methods for reducing PCB body burden. However, cholestyramine (CSA) has been found to be useful in preventing the progression of chronic progressive nephropathy in rats 4.
- Medical surveillance: Longitudinal medical surveillance programs, such as the HELPcB program, can help investigate potential adverse health effects of PCB exposure in humans 5.
- Prevention: Preventing exposure to PCBs, especially during fetal and early life, is crucial to reducing the risk of adverse health effects, including reduced IQ and altered behavior 2, 3.
Key Considerations
When managing PCBs, it is essential to consider the following:
- Environmental persistence: PCBs persist in both the environment and living organisms, making them a long-term health hazard 2.
- Occupational exposure: Workers in industries that handle PCBs are at high risk of exposure, and medical surveillance programs can help monitor their health effects 6, 5.
- Vulnerable populations: Pregnant women, fetuses, infants, and children are particularly vulnerable to the effects of PCBs, and their exposure should be minimized 3.
