Present Status and Future Perspectives on Dioxins/Furans and Polychlorinated Biphenyls Policies in Malaysia
Journal Title: Annals of Environmental Science and Toxicology - Year 2017, Vol 2, Issue 1
Abstract
Dioxins/furans and polychlorinated biphenyls (PCBs) are persistent organic pollutants (POPs) that are lipophilic and toxic in the environment. These contaminants are found in some soils, sediments, feed and food, especially dairy products, meat, fish and shellfish. The main pathway of human exposure to these pollutants is via food ingestion, estimated at over 95% of the total intake for non-occupationally exposed persons. They last a long time once they enter into the body due to their chemical stability and their lipophilic characteristic whereby they absorb by fat tissue and store in the body. Dioxins and furans contaminants are released through combustion, such as waste incineration, forest fires, volcanic eruptions and some industrial processes while PCBs are man-made chemicals and has been used because of their stability and low flammability as insulating materials in electrical equipment. Waste management is a general acute problem around the world. As one of the developing countries, Malaysia is undergoing economic growth, industrialization and urbanization, thus the proper management of larger quantity of waste being generated is of great concern.
