摘要/Abstract

摘要： 以浙江省典型农村地区3户家庭为试验地点,以不同类型生物质燃料为能源,研究不同类型炉灶、不同场所（厨房、卧室、客厅）空气PM2.5中15种多环芳烃（PAHs）的排放特征,同时采用毒性当量因子评估PAHs对人群健康的影响。结果表明,农户1、农户2室内不同地点各燃料产生的PM2.5中PAHs大小为客厅>厨房>卧室,农户3燃烧生物质燃料竹子和菌菇时室内不同地点PM2.5中PAHs浓度为厨房>客厅>卧室,而燃烧木头时,农户3卧室中PM2.5中PAHs浓度略高于客厅。3家农户燃烧生物质燃料产生的PM2.5中PAHs浓度为农户2（204.11 ng/m³）>农户3（141.65 ng/m³）>农户1（128.14 ng/m³）。PM2.5中各类PAHs厨房整体呈5~6环>3~4环>2环的变化趋势;客厅和卧室农户1和农户2整体呈2~3环>5~6环>4环的变化趋势,农户3整体呈5~6环>2~3环>4环的变化趋势。相比菌菇,竹子、木头燃烧过程中产生PAHs的较少。3家农户室内不同地点、不同燃料的致癌风险（ILCR）值大部分介于10^-6~10^-4,表明具有潜在的致癌风险。

Abstract: Three households in typical rural areas of Zhejiang province were used as experimental sites, and the different types of biomass fuels were used as energy sources to study the emission characteristics of fifteen kind of polyaromatic hydrocarbons （PAHs） in different types of stoves in PM2.5 and different places （kitchen, bedroom, living room）. At the same time, the toxicity equivalent factor was used to evaluate the impact of PAHs on the health of the population. The results showed that, the concentration of PAHs in PM2.5 produced by different households and fuels in farmer 1 and 2 was living room>kitchen>bedroom. When farmers 3 burn bamboo and mushroom, the concentration of PAHs in PM2.5 in different indoor locations was kitchen > living room > bedroom, while burning wood, the concentration of PM2.5 in bedroom was slightly higher than the living room. The concentration of PAHs in PM2.5 produced by biomass fuel in three households was ranked as follows： farmer 2（204.11 ng/m³）> farmer 3（141.65 ng/m³）> farmer 1（128.14 ng/m³）. All kinds of PAHs in PM2.5 showed an overall change trend of 5~6 rings >3~4 rings>2 rings in kitchen, but in living room and bedroom, farmer 1 and farmer 2 showed an overall change trend of 2~3 rings>5~6 rings>4 rings, and farmer 3 show an overall change trend of 5~6 rings>2~3 rings>4 rings. Biomass fuel combustion using bamboo and wood produced less PAHs than mushrooms. The ILCR in different fuels in different locations was between 10^-6 and 10^-4, indicating a potential cancer risk in three households.

Key words: biomass fuels, PM2.5, polyaromatic hydrocarbon （PAH）, ring distribution, risk assessment
