在印度尼西亚苏门答腊岛占碑市两个不同特征的监测点进行了12小时昼间和夜间的空气采样。 2019年8月2日至9日和8月7日至13日分别在路边和河边进行了采样。使用级联空气采样器来获取有关空气颗粒物的状态、特征和行为的信息，特别关注超细颗粒物 (PM0.1)。轻型车辆的数量与大多数 PM 粒径类别的相关性最好，而重型车辆和摩托车的数量在夜间分别与 0.5-1 μm 和 > 10 μm 相关。这些研究结果表明，交通量对 PM 浓度有积极影响。使用与重型车辆排放相关的碳质参数（例如 EC 和烟尘-EC），证实高压排放能够更清楚地解释路边环境中的 PM0.1 分数。 0.5-1μm颗粒物的OC/EC和EC之间的相关性表明生物质燃烧在昼夜期间对两者都有影响。可能的跨界影响表现为 PM0.1 分数特征从“城市”到“生物质燃烧”的转变。
Air sampling for 12 h diurnal and nocturnal periods was conducted at two monitoring sites with different characteristics in Jambi City, Sumatra Island, Indonesia. The sampling was done at a roadside site and a riverside site from 2-9 August, and from 7-13 August in 2019, respectively. A cascade air sampler was used to obtain information on the status, characteristics and behavior of airborne particles with a particular focus on the ultrafine fraction (PM0.1). The number of light vehicles was best correlated with most PM size categories, while those of heavy vehicles and motorcycles with the 0.5-1 mu m and with > 10 mu m for the nocturnal period, respectively. These findings suggest that there is a positive influence of traffic amount on the PM concentration. Using carbonaceous parameters related to heavy-vehicle emissions such as EC and soot-EC, HV emission was confirmed to account for the PM0.1 fraction more clearly in the roadside environment. The correlation between OC/EC and EC for 0.5-1 mu m particles indicated that biomass burning has an influence on both in the diurnal period. A possible transboundary influence was shown as a shift in the PM0.1 fraction characteristic from "urban " to "biomass burning ".
