    Dioxin & Furan

    Dioxin and Furans are basically the toxic chemicals which are created when other chemicals are manufactured. Generally, Dioxin and Furans are formed as the by-products for example during the production of Chlorinated phenols, chlorinated di-phenyl ether and many more. These compounds do not occur naturally, nor they are produced intentionally.

    A by-product of industrial processes such as waste incineration, chemical manufacturing and paper bleaching, dioxins and furans can be found in the air, in water and contaminated soil. These, then accumulate in animal tissues and pass onto humans through the food chain thereafter.

    Polychlorinated dibenzo-para-dioxin (PCDDs) and Polychlorinated dibenzofuran (PCDFs) are chlorinated aromatic compounds having tremendous toxic effects, carcinogenicity and persistence in the environment; hence these Persistent Organic Pollutants (POPs) are real threats to the environment and existence of mankind. Dioxin and Furans can accumulate in animal tissues and pass onto humans through the food chain thereafter.

    EFRAC has world-class laboratory services, all of which operate with strict adherence, guidelines such as ISO 17025. Our scientists of adequate expertise in separation techniques and have profound knowledge of analyzing unknown chemical compounds. Specialists with industry based experience can analyze cases and deduce the root cause of reported problems.
