Polychlorinated biphenyls (PCBs) in bottom sediments: Identification of sources

The purpose of this work was to identify the probable PCBs emission sources in bottom sediments using available data, that is polycyclic aromatic hydrocarbon diagnostic ratios. The numerical ratios of pairs of compounds such as fluoranthene/pyrene, phenanthrene/anthracene, fluoranthene/(fluoranthene + pyrene) and chrysene/benzo[a]anthracene are generally used as a tool for identifying and assessing pollution emission sources.
