Polychlorinated Biphenyls (PCBs) are a class of man-made organic compounds with no known natural source, commercially produced for a wide variety of uses in 1900s. Their chemical properties, such as non-flammability, heat resistance, insulation) and physical stability contribute to their environmental persistence.
Exposure to PCBs can cause human and wildlife health issues with acute and chronic effects.
Starting from 1960s, GC/ECD configuration has been widely used for the analysis of PCBs. This configuration became by the time very popular and routinely applied for the analysis of PCBs.
