Long-Term Temporal Trends of Polychlorinated Biphenyls and Their Controlling Sources in China

Polychlorinated biphenyls (PCBs) are industrial organic contaminants identified as persistent, bioaccumulative, toxic (PBT), and subject to long-range transport (LRT) with global scale significance. This study focuses on a reconstruction and prediction for China of long-term emission trends of intentionally and unintentionally produced (UP) ∑7PCBs (UP-PCBs, from the manufacture of steel, cement and sinter iron) and their re-emissions from...
