室内固体燃料燃烧是多环芳烃（PAHs）和氧化多环芳烃（OPAHs）的主要来源，后者被认为比前者毒性更大。然而，关于固体燃料燃烧产生的OPAH排放量的定量信息有限。在模拟厨房条件下，测定了9种常用农作物秸秆和5种中国农村常用的典型家用炉灶燃烧的煤的OPAHs排放因子（EFOPAH）。作物残留物的EFOPAH总量为2.8±0.2 ~ 8.1±2.2 mg/kg，煤的EFOPAH总量为0.043 ~ 71 mg/kg，其中9-芴酮含量最高。室内秸秆焚烧的EFOPAH比露天焚烧高1~2个数量级，且受燃料性质和燃烧条件（如水分和燃烧效率）的影响。对于作物残留物和煤，显着的正相关性之间的EFs的个别OPAHs和母体多环芳烃。氧化速率Ro定义为氧化的PAH和母体PAH物种之间的EFs的比率，以描述OPAH的形成潜力。对于所研究的OPAH/PAH对，作物残体的Ro值为0.16 ~ 0.89，煤的Ro值为0.03 ~ 0.25。炉灶内焚烧的秸秆Ro远高于露天焚烧，而远低于大气中的焚烧，说明存在OPAH的二次生成和多环芳烃损失的影响。与母体多环芳烃相比，OPAHs更易与颗粒物（PM）结合，尤其是细颗粒物，其主要粒径范围为0.7 ~ 2.1 μm（秸秆和高粘结性煤）和< 0.7 μm（低粘结性型煤）。
Indoor solid fuel combustion is a dominant source of polycyclic aromatic hydrocarbons (PAHs) and oxygenated PAHs (OPAHs) and the latter are believed to be more toxic than the former. However, there is limited quantitative information on the emissions of OPAHs from solid fuel combustion. In this study, emission factors of OPAHs (EFOPAH) for nine commonly used crop residues and five coals burnt in typical residential stoves widely used in rural China were measured under simulated kitchen conditions. The total EFOPAH ranged from 2.8±0.2 to 8.1±2.2 mg/kg for tested crop residues and from 0.043 to 71 mg/kg for various coals and 9-fluorenone was the most abundant specie. The EFOPAH for indoor crop residue burning were 1~2 orders of magnitude higher than those from open burning, and they were affected by fuel properties and combustion conditions, like moisture and combustion efficiency. For both crop residues and coals, significantly positive correlations were found between EFs for the individual OPAHs and the parent PAHs. An oxygenation rate, Ro, was defined as the ratio of the EFs between the oxygenated and parent PAH species to describe the formation potential of OPAHs. For the studied OPAH/PAH pairs, mean Ro values were 0.16 ~ 0.89 for crop residues and 0.03 ~ 0.25 for coals. Ro for crop residues burned in the cooking stove were much higher than those for open burning and much lower than those in ambient air, indicating the influence of secondary formation of OPAH and loss of PAHs. In comparison with parent PAHs, OPAHs showed a higher tendency to be associated with particulate matter (PM), especially fine PM, and the dominate size ranges were 0.7 ~ 2.1 µm for crop residues and high caking coals and < 0.7 µm for the tested low caking briquettes.
