    49、2010+A1:2013 (E) 5 Introduction Polychlorinated biphenyls (PCBs) are a group of chlorinated aromatic compounds similar in structure to polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) which consist of 209 individual substances (see Figure 1 for the basic structure). PCBs have been produced intentionally over approximately 50 years until the end of the 1990s with different uses in open and closed systems, e.g. as electrical insulators or dielectric fluids in capacitors and transformers, specialised hydraulic f
