Short summary
Relative humidity (RH) affects brown carbon (BrC) light absorption and radiative forcing, but this relationship is still unclear. Using field observations across wide RH and pollution ranges with molecular-level measurements, this study shows that RH non-linearly affects water-soluble BrC absorption, with magnitude varying by pollution level. Molecular analysis reveals the mechanisms, improving understanding of BrC radiative effects and aiding humidity-dependent absorption in climate models.

Short summary
Burning biomass releases black carbon (BC), but its precursors are unclear. We burned two fuels at three temperatures, measuring particles, gases, and BC. Furans, oxygenated aromatics, single-ring aromatics, and polycyclic aromatic hydrocarbons correlated with BC in the particle phase. Higher temperatures boosted BC—not by producing more precursors, but by converting them efficiently. Different fuels also produced distinct molecular fingerprints. These explain why BC emissions vary so much.

Water-soluble organic nitrogen (WSON) in coastal aerosols is critical for atmospheric chemistry and climate processes. This Bangkok study found sea-spray aerosol (SSA) is an important contributor to coastal aerosol WSON under marine air, its contribution surging from 3.8 % (continental) to 34 %. SSA-associated WSON strongly correlated (r=0.96) with trajectory-based air-mass exposure to chlorophyll-a, which is consistent with marine-biogenic enhancement.

Our study indicates fossil fuel CO2 (CO2ff) reductions in Chinese megacities via atmospheric Δ(14CO2) and δ(13CO2) measurements, driven by coal-to-gas transitions and combustion efficiency improvement. The 24-year record show steeper declined urban RCO/CO2ff ratios than inventory estimates, implying underestimation of efficiency improvements and CO reductions. Integrating top-down observations with inventories is critical to track policy-driven emission shifts and optimize co-benefit strategies.

This study investigated the evolution of biomass and water-soluble organic matter (WSOM) derived from coal combustion during an aqueous photochemical process. The results indicate that photochemical aging induces distinct changes in the optical and molecular properties of WSOM. More pronounced alterations were observed during OH photooxidation than direct photolysis. Our results also demonstrate that atmospheric photooxidation may represent a significant source of black-carbon-like substances.

Urban areas exhibit high carbon footprints yet significant mitigation potential, requiring precise quantification of CO2 sources for effective carbon budgeting. While previous studies focused predominantly on fossil fuel CO2, biogenic CO2 (CO2bio) dynamics remain less understood. Here we show that Δ14CO2 tracers – combined with multi-source data – enable partitioning of CO2bio into three components and identification of their seasonal drivers, advancing our understanding of urban carbon budgets.

We developed a large, open-access dataset of mountain soil chemistry in China, based on over 1,300 samples from 166 sites across diverse climates and vegetation types. The dataset includes concentrations of 24 elements and key environmental variables like temperature, rainfall, and soil properties. This dataset offers a valuable resource for studying mountain ecosystems, supporting Earth system modeling, and predicting how soils respond to environmental change.

In this study, we found that biomass burning (31.0 %) and coal combustion (31.1 %) were the dominant sources of water-insoluble organic carbon in China, with coal combustion sources exhibiting the strongest light-absorbing capacity. Additionally, we propose a light-absorbing carbonaceous continuum, revealing that components enriched with fossil sources tend to have stronger light-absorbing capacity, higher aromaticity, higher molecular weights, and greater recalcitrance in the atmosphere.

This is the first report of long-term atmospheric PAH monitoring around the Bohai Sea. The results showed that the concentrations of PAHs in the atmosphere around the Bohai Sea decreased from June 2014 to May 2019, especially the concentrations of highly toxic PAHs. This indicates that the contributions from PAH sources changed to a certain extent in different areas, and it also led to reductions in the related health risk and medical costs following pollution prevention and control.

This is the first report of ship-emitted nitrogen stable isotope composition (δ15N) of nitrogen oxides (NOx). The results showed that δ15N–NOx from ships was −18.5 ± 10.9 ‰ and increased monotonically with tightening emission regulations. The selective catalytic reduction system was the most vital factor. The temporal variation in δ15N–NOx was evaluated and can be used to select suitable δ15N–NOx for a more accurate assessment of the contribution of ship-emitted exhaust to atmospheric NOx.

The results show that 14C elemental carbon (EC) was not only related to the isolation method but also to the types and proportions of the biomass sources in the sample. The hydropyrolysis (Hypy) method, which can be used to isolate a highly stable portion of ECHypy and avoid charring, is a more effective and stable approach for the matrix-independent 14C quantification of EC in aerosols, and the 13C–ECHypy and non-fossil ECHypy values of SRM1649b were –24.9 ‰ and 11 %, respectively.

N-NH4+ and N-NO3- were vital components in nitrogenous aerosols and contributed 69 % to total nitrogen in PM2.5. Coal combustion was still the most important source of urban atmospheric NO3-. However, the non-agriculture sources play an increasingly important role in NH4+ emissions.

This study provides a comprehensive molecular identification of atmospheric common fluorescent components and deciphers their related formation pathways. The fluorescent components varied in molecular composition, and a dominant oxidation pathway for the formation of humic-like fluorescent components was suggested, notwithstanding their different precursor types. Our findings are expected to be helpful to further studies using the EEM-PARAFAC as a tool to study atmospheric BrC.

This work comprehensively investigated the fluorescence data of light-absorbing organic compounds, water-soluble organic matter in different types of aerosol samples, soil dust, and fulvic and humic acids using an excitation–emission matrix (EEM) method and parallel factor modeling. The results revealed which light-absorbing species can be detected by EEM and also provided important information for identifying the chemical composition and possible sources of these species in atmospheric samples.

In this study, PM2.5 samples were obtained during a winter haze event in Guangzhou, China, and light absorption and molecular composition of humic-like substances (HULIS) were investigated by UV–Vis spectrophotometry and ultrahigh-resolution mass spectrometry. The findings obtained present some differences from the results reported in other regions of China and significantly enhanced our understanding of HULIS evolution during haze bloom-decay processes in the subtropic region of southern China.

We conducted field observation employing Fourier transform ion cyclotron resonance mass spectrometry to characterize the molecular composition and major formation pathways or sources of organosulfur compounds in Guangzhou, where is heavily influenced by biogenic–anthropogenic interactions and has high relative humidity and temperature. We suggested that heterogeneous reactions such as SO2 uptake and heterogeneous oxidations are important to the molecular variations of organosulfur compounds.

Short summary
We analyzed compound-specific dual-carbon isotope signatures (Δ14C and δ13C) of dominant secondary organic aerosol (SOA) tracer molecules (i.e., oxalic acid) to investigate the fates of SOAs in the atmosphere at five emission hotspots in China. The results indicated that SOA carbon sources and chemical processes producing SOAs vary spatially and seasonally, and these variations need to be included in Chinese climate projection models and air quality management practices.
We analyzed compound-specific dual-carbon isotope signatures (Δ14C and δ13C) of dominant...
