Potential risk of remaining PCBs and management strategies in Europe

Kikuchi R., Santos S. M., Gerardo R.

Environmental Biotechnology

2006

Vol. 2, No. 2

69-77

Polychlorinated biphenyls (PCBs) are persistent hazardous chemicals and are now out of production worldwide. Although over 20 years have passed since the Helsinki Convention promoted the elimination of PCB use, it is difficult to put an end to PCB emissions in a short time because PCBs have a long lifetime in the environment and a major portion of PCBs are emitted from electrical equipment manufactured before the Helsinki Convention but still used today. PCBs have an impact on human sperm integrity in the European male population; furthermore, Arctic ecosystems such as those supporting polar bears and seals are exposed to risks due to the long-distance transport of PCBs. Most European countries have no proper facilities for PCB treatment. After analyzing extensive information about PCB treatments, it is concluded that the thermal process is technically sound and cost-effective. This study contributes to the promotion of treatments in most European countries storing PCBs with the aim of pursuing a sustainable future.
