Christina N Vasilakopoulou et al.
The oxidation of biogenic volatile organic compounds (bVOCs) is a significant source of secondary organic aerosols (SOA). This study investigates later-generation SOA formation from the reactions of three first-generation sesquiterpene ozon...
Potential Errors in CMAQ NO:NO2 Ratios and Upper Tropospheric NO2 Impacting the Interpretation of TROPOMI Retrievals [0.03%]
化学运输模型及NO和NO2比率的潜在误差及其对上层对流层NO2的影响和对TROPOMI反演结果的解读
Abiola S Lawal,T Nash Skipper,Cesunica E Ivey et al.
Abiola S Lawal et al.
Although Chemical Transport Models (CTMs) such as the Community Multiscale Air Quality Model (CMAQ) have been used in linking observations of trace gases to emissions and developing vertical column distributions, there remain consistent bia...
Unique Microphysical Structures of Ultrafine Particles Emitted from Turbofan Jet Engines [0.03%]
涡轮风扇喷气发动机超细颗粒物的独特微结构

Akihiro Fushimi et al.
The impact of aircraft exhaust particles on human health and climate are raising concerns globally. Particle number concentrations in exhaust plumes of turbofan jet engines, which are commonly used in civil aviation, are generally dominated...
The Invisible Footprint of Climbing Shoes: High Exposure to Rubber Additives in Indoor Facilities [0.03%]
攀岩鞋的隐形足迹——室内场所橡胶添加剂的高暴露风险
Anya Sherman,Thibault Masset,Lukas Wimmer et al.
Anya Sherman et al.
There is growing concern about rubber-derived compounds (RDCs), predominantly originating from tire and road wear particles. Other consumer products, including sports equipment, also contain RDCs, and human exposure to these compounds is of...
Enhancing Differentiation of Oxygenated Organic Aerosol: A Machine Learning Approach to Distinguish Local and Transboundary Pollution [0.03%]
改进有机气溶胶判别方法：利用机器学习区分本地和区域污染
Lu Lei,Wei Xu,Chunshui Lin et al.
Lu Lei et al.
Accurate source apportionment of particulate matter (PM), especially of organic aerosol (OA), is crucial for targeted mitigation efforts. Positive Matrix Factorization (PMF) is powerful in source attribution of primary OA (POA); however, it...

Estimating Power Plant Contributions to Surface Pollution in a Wintertime Arctic Environment [0.03%]
极地冬季电力工业对地面污染的贡献估算研究
Natalie Brett,Steve R Arnold,Kathy S Law et al.
Natalie Brett et al.
Arctic winter meteorology and orography in the Fairbanks North Star Borough (FNSB, interior Alaska) promote stably stratified boundary layers, often causing acute pollution episodes that exceed the US-EPA National Ambient Air Quality Standa...
A Machine Learning Approach for Predicting the Pure-Component Surface Tension of Atmospherically Relevant Organic Compounds [0.03%]
一种预测 atmospherically 有关有机化合物纯组分表面张力的机器学习方法

Cassandra Johannessen et al.
Tire-derived chemicals (TDCs) are shown to be elevated in urban environments. In this study, we analyzed 6PPD-quinone, 2,2,4-trimethyl-1,2-dihydroquinoline (TMQ), hexa(methoxy)methylmelamine (HMMM), as well as selected benzothiazoles and be...
Wildland fire smoke adds to disproportionate PM2.5 exposure in the United States [0.03%]
美国野火烟雾加剧了细颗粒物暴露的不平等现象
R Byron Rice,Jason D Sacks,Kirk R Baker et al.
R Byron Rice et al.
Wildland fire (i.e., prescribed fire and wildfire) smoke exposure is an emerging public health threat, in part due to climate change. Previous research has demonstrated disparities in ambient fine particulate matter (PM2.5) exposure, with B...
