Nitrated polycyclic aromatic hydrocarbons (NPAHs) and oxygenated polycyclic aromatic hydrocarbons (OPAHs) are two important derivatives of polycyclic aromatic hydrocarbons (PAHs). Samples from households in Tianjin indoor dust deposition were collected from April to May 2023 in this study. The concentrations of 18NPAHs and 5OPAHs were analyzed by GC-MS, and the concentration characteristics and source apportionment of these substances were discussed. The results showed that the median concentrations of ∑₁₈NPAHs and ∑₅OPAHs in Tianjin indoor dust deposition were 37.95 and 248.82ng/g, respectively. The median concentrations of ∑₁₈NPAHs and ∑₅OPAHs in the urban area were slightly higher than those in the surrounding urban area.There were no significant differences in these substance concentrations of ∑₁₈NPAHs and ∑₅OPAHs between the urban area and the surrounding urban area in Tianjin. From the perspective of different influencing factors, there was a statistically significant difference in the impact of smoking habits and energy types on the monomer concentrations of some NPAHs and OPAHs in Tianjin indoor dust deposition. The results of the characteristic ratio method showed that NPAHs in Tianjin indoor dust deposition mainly originated from primary emissions of combustion sources and vehicle exhaust emissions, and some secondary generation mainly formed by OH· catalytic reactions.

硝基多环芳烃（NPAHs）和氧化多环芳烃（OPAHs）是两种重要的多环芳烃（PAHs）衍生物．本研究于2023年4~5月采集天津市住宅室内降尘样品，利用GC-MS分析18种NPAHs和5种OPAHs浓度，探讨了目标物的浓度特征并进行来源解析．结果显示：天津室内降尘中∑₁₈NPAHs和∑₅OPAHs浓度中位值分别为37.95和248.82ng/g．市区∑₁₈NPAHs和∑₅OPAHs浓度中位值略高于环城区，市区和环城区∑₁₈NPAHs和∑₅OPAHs的浓度不存在显著性差异．从不同影响因素来看，吸烟习惯和能源类型对室内降尘中部分NPAHs和OPAHs的单体浓度的影响差异有统计学意义．特征比值法结果显示，天津室内降尘中NPAHs主要来自燃烧源一次排放和汽车尾气排放，还有部分以OH·催化反应为主的二次生成．
