Determination of Contaminants - Analysis of Sum of Indicator Polychlorinated Biphenyls (PCB)

Polychlorinated biphenyls (PCBs) are chemical pollutants classified as persistent organic pollutants. Although their use has been banned for many years, polychlorinated biphenyls are still dispersed in the environment. Therefore, all living organisms are exposed to these compounds. Foods, especially fatty foods such as milk, are one of the main sources of human exposure to these chemical pollutants.

Polychlorinated biphenyls belong to the group of chemical pollutants classified as persistent organic pollutants due to their being biotic organisms and their ability to bioaccumulate. Polychlorinated biphenyls containing around 210 species are mainly grouped into dioxin-like PCBs and non-dioxin-like PCBs. The second group is called indicator PCBs.

Polychlorinated biphenyls (PCBs) are composed of a chlorine atom attached to a biphenyl, a molecule chemically composed of two benzene rings containing six carbons each. These organic compounds have no taste or odor and are clear, light yellow, viscous liquids. Production of polychlorinated biphenyls is prohibited because of their high toxicity.

Due to their physical and chemical properties, polychlorinated biphenyls accumulate at different levels in soil, air and water. They can also be transported long distances by air.

In the test, analysis, measurement and evaluation studies carried out in our organization, national and international standards and applicable legal regulations are complied with and reliable and impartial results are obtained. These studies are based on the latest technological equipment, trained and experienced staff and modern methods. Among the numerous tests carried out in this context, there are also services for the determination of contaminants - the analysis of the sum of indicator polychlorinated biphenyls (PCB).
