在南亚，用于住宅供暖和烹饪的固体燃料燃烧是颗粒相多环芳烃（p-PAHs）的主要排放源，多环芳烃是一种对人类健康的强致癌物。目前在区域清单模型中使用的多环芳烃排放因子（EFs）和源诊断比率是根据受控实验室测试估计的，这些测试不能准确反映在印度农村家庭中观察到的真实燃烧情景。因此，与室内和环境空气中多环芳烃水平相关的健康影响可能被严重低估和低估。我们在印度次大陆的10个不同的邦进行了一项全国性的研究，以评估美国环境保护署（EPA）确定的住宅固体生物质燃烧排放的16种高优先级多环芳烃的EFs和来源诊断比率。我们估计的平均年EFs比以前基于实验室的调查报告高2.4-18.3倍。致癌毒性分析表明，与其他多环芳烃相比，粪饼和煤球这两种广泛使用的住宅固体燃料的燃烧风险最大（分别为80%和59%），因为主要排放的是苯并[a]芘。我们的研究结果强调了改进实验室测试和现场验证的重要性，这是实现更准确的排放清单和更好地评估公共卫生影响的关键步骤。
In South Asia, combustion of solid fuel for residential heating and cooking is a major emission source of particulate-phase polycyclic aromatic hydrocarbons (p-PAHs), a potent carcinogen for human health. The emission factors (EFs) and source diagnostic ratios of PAHs currently used in regional inventory models have been estimated from controlled laboratory tests, which do not accurately reflect real-world combustion scenarios observed in rural Indian households. Consequently, the health effects associated withp-PAH levels in indoor and ambient air could be severely underestimated and undervalued. We performed a nationwide study across ten different states in the Indian subcontinent to evaluate the EFs and source diagnostic ratios of sixteen U.S. Environmental Protection Agency (EPA) identified high priorityp-PAHs emitted from residential solid biomass combustion. Our estimated average annual EFs were 2.4–18.3 fold higher than those reported from previous laboratory-based investigations. Carcinogenic toxicity analysis shows that combustion of dung cake and coal ball, both widely used residential solid fuels, posed the most risk (80% and 59% respectively) in comparison to other PAHs owing to predominant emission of benzo[a]pyrene. Our findings underscore the importance of improved laboratory testing and field validations as crucial steps toward more accurate emission inventories and better assessment of public health impacts.
