In order to explore the mechanism of haze formation, the meteorological effect and chemical
reaction process of the explosive growth (EG) of PM2. 5 were studied. In this study, the level …

Organosulfates in atmospheric PM2. 5 were investigated at two urban sites in Hefei and
Shijiazhuang of southern and northern China during the summer and winter seasons of …

Quantitative assessment of gas-particle partitioning of individual components within complex
atmospheric organic aerosol (OA) mixtures is critical for predicting and comprehending the …

Here we present seasonal chemical characteristics, formations, sources of PM 2.5 in the
year 2020 in Suzhou, Yangtze River Delta, China. Expectedly, organic matter (OM) found to …

Aromatic acids are an integral component of organic acids in the atmosphere, contributing to
the formation of climate-altering brown carbon (BrC). To better understand the sources and …

Isoprene and ammonia (NH 3) are essential precursors for organic and inorganic aerosol in
the atmosphere, but their molecular interactions are unclear. The fundamental role of NH 3 …

In this study, we developed an observation based photochemical box model with the
measurement data collected at a suburban site (ie, the Xianghe, XH site) of the Beijing …

Aerosol water affects the physicochemical properties and mass concentration of organic
aerosols (OA), but it is typically omitted by air quality, weather, and climate models. We …

Elucidating the mutual effects between the different volatile organic compounds (VOCs) is
crucial for comprehending the formation mechanism of atmospheric secondary organic …

Pyruvic acid (PA) is a model for amphiphilic oxygenated organic compounds, and together
with its hydrogen-bonded (H-bonded) water complexes, their presence can alter …
