POLYCHLORINATED NAPHTHALENE PROFILES IN HUMAN SERUM AND FLUE GAS FROM THE METROPOLITAN AREA
Polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and polychlorinated biphenyls (PCBs) have been studied extensively; however, polychlorinated naphthalenes (PCNs) have been studied less widely. The concentrations of PCNs in the serum samples of 61 healthy human volunteers and in 10 stack gas samples of municipal solid waste incinerators (MSWIs) were measured by gas chromatography/highresolution mass spectrometry (GC/HRMS). The mean concentration of PCNs in human serum was 2170 pg/g lipid, and the most predominant individual congener was hepta-CN-73. The overall serum PCN homologue profiles of all subjects were dominated by tetra- and penta-CN homologues. Whereas the total PCN concentrations in all stack gas samples varied between 0.07 and 1.51 ng/Nm3, the average PCN homologue profile in the flue gas samples was dominated by the tetra- and hepta-CN homologues. Enrichment of hepta-CN- 73 in the human serum samples might be due to contributors from combustion sources.
