Estimation and congener specific characterization of PCNs emission from secondary nonferrous metallurgies in China

摘要：

Secondary nonferrous production is addressed as one of the potential sources of unintentional produced persistent organic pollutants (UP-POPs) due to the impurity of raw material. However, the release inventory of polychlorinated naphthalenes (PCNs) is very scarce for these secondary nonferrous metallurgies. This study selected the typical secondary copper, aluminum, zinc and lead plants to investigate the emissions of PCNs released from secondary nonferrous production in China. In stack gas of secondary nonferrous production, the lower chlorination PCNs are the dominant homologues where Mono to Tri CNs make the most important contribution to the concentration. However, for fly ash, the higher chlorination PCNs like OCN is the dominant homologue.
