Comprehensive Review of Polychlorinated Biphenyls (PCBs)
May 2024 - Sep 2024
-
Polychlorinated biphenyls (PCBs) are toxic, synthetic chemicals known for their stability and insulating properties, widely used before being banned in many countries. Due to their persistence, they accumulate in ecosystems and pose serious health and environmental risks. This project explores PCB sources, impacts, remediation methods, and strategies for effective management.
PCB Research Summary
In this project, I conducted an in-depth literature review on polychlorinated biphenyls (PCBs), examining their sources, environmental behavior, health impacts, and remediation strategies.
Key Findings:
Sources & Pathways: Once used in transformers, paints, and sealants, PCBs persist in the environment, spreading via air, water, soil, and entering the food chain through urban runoff and sediment erosion.
Health Impacts: PCBs are linked to cancer, immune suppression, neurological damage (especially in children), and reproductive and endocrine disruption.
Remediation Strategies:
Biological: Phytoremediation and microbial methods are eco-friendly but slow.
Chemical: Dehalogenation and activated carbon treatments offer quicker results but face scaling issues.
Emerging: Nanotechnology and hybrid approaches show future potential.Future Outlook: Emphasis on advanced, scalable remediation technologies, stronger regulations, and global collaboration to reduce PCB risks.
