Region-specific characterization and ecotoxicity assessment of PAH compounds in winter PM2.5 from three capital cities in Northeast Asia

Type: article
Abstract: ) had lower PAH levels but a higher share of secondary products, including oxygenated (OPAHs) and nitrogen-containing PAHs (NPAHs). Overall, 646 PAH compounds were identified: UB was dominated by methylated alkyl and sulfur-containing PAHs, while BJ and SE had more hydroxylated and carbonylated PAHs. QSAR ecotoxicity analysis indicated the highest toxicity in SE from hydroxylated PAHs and a broader toxic range in UB. These findings support air quality strategies to reduce coal combustion in UB and secondary PAH formation in BJ and SE.
