Dioxins and PCBs


Dioxins are released as unintentional byproducts in burning and chlorination processes. Polychlorinated biphenyls (PCBs) have been used for example as heat transfer and insulation fluids in capacitors and transformers. The EU has set maximum limits on the levels of dioxins and PCBs allowed in fish and other foods.
The analytical methods for dioxins and PCBs are accredited with a flexible scope. This means that the methods are suitable for most sample matrixes.
The unit provides analytical services on a routine basis and accepts individual samples as well as samples from larger research projects. Details of the method are given in the Analytical Services brochure.
