  • Analysis of PCBs in emission samples: non ortho, mono-ortho and homolog totals by level of chlorination

    IntroductionPolychlorinated biphenyls (PCBs) are one of the most widespread persistent organic pollutants, identified in every component of the global ecosystem. A production of approximately 2 * 10 9 Kg technical PCB occurred form 1930 to the late 1970 1 and the total amount released into the environment is estimated in 370. 000 2 tonnes. Twelve of the possible 209 PCBs are non- and mono-ortho ...
