Air pollution poses significant threat to human health and the environment, as well as millions of people's quality of life. Air pollution in Jakarta, one of the megacities in Asia, has attracted concern from the government and the public. Long term air quality monitoring of fine and coarse atmospheric particulate matter (PM) was conducted in Central Jakarta from 2010 to 2019. The PM samples were collected for 24 h using a Gent-stacked filter unit sampler. Mass concentrations, black carbon (BC) as well as elemental concentrations were measured. X-ray fluorescence was used to quantify the elemental species. Measurement of PM_2.5 from 2010 to 2019, showed that the annual average values always exceeded the Indonesian national ambient air quality standard (NAAQS) of 15 μg/m³ and had an increasing trend. Seasonal variations of PM_2.5 were observed with maxima during the dry season with frewuent exceedances of the 24-hr NAAQS. Temporal variations of the ratios of PM_2.5 to PM₁₀, and the reconstructed mass were explored. PM_2.5 concentrations in Jakarta were dominated by BC representing about 20% and sulfur with an average of 912 ng/m³ and a maximum value of 4199 ng/m³. Sulfur is mainly related to the coal-fired power plants emissions, and high sulfur gasoline and diesel combustion in vehicles. Sulfate showed an increasing trend suggesting increasing emissions. PM_2.5-10 was dominated by the crustal elements. The reconstructed mass results also showed that BC and sulfate were the largest contributors to PM_2.5 with an average share of 39%. Soil contributed about 30% to PM_2.5-10. This study provides useful information on possible PM sources in Jakarta and long-term trend of PM concentrations for policy intervention and health effect studies.

空气污染对人类健康和环境以及数百万人的生活质量构成了重大威胁。雅加达是亚洲大城市之一，空气污染引起了政府和公众的关注。从2010年至2019年，在雅加达中部进行了长期空气质量监测，监测了细小和粗略的大气颗粒物（PM）。使用Gent堆叠式过滤器单元采样器收集了24 h的PM样品。测量了质量浓度，黑碳（BC）以及元素浓度。X射线荧光用于定量元素种类。从2010年到2019年对PM _2.5的测量显示，年平均值始终超过印度尼西亚国家环境空气质量标准（NAAQS）的15μg/ m ³并且呈上升趋势。在干旱季节，PM _2.5的季节变化最大，超过24小时的NAAQS。探索了PM _2.5与PM ₁₀的比率随时间的变化以及重建质量。雅加达的PM _2.5浓度主要由BC所占，约占20％，而硫则为912 ng / m ³，最大值为4199 ng / m ³。硫主要与燃煤发电厂的排放以及车辆中高硫汽油和柴油的燃烧有关。硫酸盐呈上升趋势，表明排放增加。下午_2.5-10被地壳元素主导。重建的质量结果还显示，BC和硫酸盐是PM _2.5的最大贡献者，平均份额为39％。土壤对PM _2.5-10的贡献约为30％。这项研究提供了有关雅加达可能的PM来源以及PM浓度长期趋势的有用信息，以用于政策干预和健康影响研究。
