在印度尼西亚苏门答腊岛泥炭火灾期间进行了深入的实地研究，以调查泥炭烟雾中颗粒物排放的物理和化学特征，并为源受体分析提供必要的数据。在距泥炭火不同距离的三个不同地点进行了环境空气采样，以确定 PM2.5 的质量和数量浓度及其化学成分（碳质和含氮物质、多环芳烃、水溶性无机和有机离子、总金属和水溶性金属）的变化。这三个地点代表直接受当地泥炭燃烧影响的农村地点、半农村地点和位于泥炭火灾下风向的城市地点。泥炭火灾附近PM2.5质量浓度和空气颗粒物数浓度分别高达1600微克/立方米和1.7×10(5)cm(-3)。泥炭烟霾中PM2.5的主要成分是碳质颗粒，特别是有机碳、NO3-和SO4(2-)，含量较少的成分包括NH4+、NO2-、Na+、K+等离子，有机酸以及Al、Fe、Ti等金属。通过化学质量平衡受体模型进行的源解析表明，泥炭烟雾可以传播很长的距离，并显着影响顺风位置的空气质量。
An intensive field study was conducted in Sumatra, Indonesia, during a peat fire episode to investigate the physical and chemical characteristics of particulate emissions in peat smoke and to provide necessary data for source-receptor analyses. Ambient air sampling was carried out at three different sites located at varying distances from the peatfires to determine changes in mass and number concentrations of PM2.5 and its chemical composition (carbonaceous and nitrogenous materials, polycyclic aromatic hydrocarbons, water-soluble inorganic and organic ions, and total and water-soluble metals). The three sites represent a rural site directly affected by the local peat combustion, a semirural site, and an urban site situated downwind of the peat fires. The mass concentration of PM2.5 and the number concentration of airborne particles were as high as 1600 microg/m3 and 1.7 x 10(5) cm(-3), respectively, in the vicinity of peat fires. The major components of PM2.5 in peat smoke haze were carbonaceous particles, particularly organic carbon, NO3-, and SO4(2-), while the less abundant constituents included ions such as NH4+, NO2-, Na+, K+, organic acids, and metals such as Al, Fe, and Ti. Source apportionment by chemical mass balance receptor modeling indicates that peat smoke can travel long distances and significantly affect the air quality at locations downwind.
