We developed a high time resolution method for determining the δ13C values of WSOCp and WSOCg by combination of wet oxidation pretreatment and IRMS. With improvement of oxidation method and determination method, δ13C value of liquid sample with a carbon content between 0.5 to 5 μg can be determined with an accuracy of 0.6 ‰. Using this method, the δ13C value of WSOCp and WSOCg in winter of 2021 at an urban site of Nanjing were determined, which were -25.9 ± 0.7 ‰ and -29.9 ± 0.9 ‰ respectively.

Levels of hydroxymethanesulfonate (HMS) in a continental city and, for the first time, a marine atmosphere are reported. The effect of aerosol ionic strength (IS) on HMS formation was quantified; it first rises with increasing IS and then peaks at 4 mol kg−1 before declining. Given the IS range of marine (2–6) and urban (6–20 mol kg−1) aerosols and the clearly negative correlation between humidity and IS, moderate IS levels in humid conditions may notably boost ambient HMS formation.

In this study, we present the first report on the annual variation of stable oxygen isotope anomalies in nitrate (NO3−) collected from the urban area of Lhasa, on the Tibetan Plateau, China. Using a Bayesian isotope mixture model, we found that the relative contribution of the NO3 + volatile organic compound (VOC) pathway to NO3− formation in spring in Lhasa was several times higher than that in urban cities, highlighting the significant influence of VOCs transported from outside the Tibetan Plateau.

To improve air quality, the Chinese government has implemented strict clean-air measures. We explored how black carbon (BC) responded to these measures and found that a reduction in liquid fuel use was the main factor driving a decrease in BC levels. Additionally, meteorological factors also played a significant role in the long-term trends of BC. These factors should be considered in future emission reduction policies to further enhance air quality improvements.

Reports on molecular-level knowledge of high-temporal-resolution particulate matter ≤2.5 µm in diameter (PM2.5) on hazy days are limited. We investigated various PM2.5 species and their sources. The results show biomass burning (BB) was the main source of organic carbon. Moreover, BB enhanced fungal spore emissions and secondary aerosol formation. The contribution of non-fossil sources increased with increasing haze pollution, suggesting BB may be an important driver of haze events in winter.

Using an updated soil reactive nitrogen emission scheme in the Unified Inputs for Weather Research and Forecasting coupled with Chemistry (UI-WRF-Chem) model, we investigate the role of soil NO and HONO (Nr) emissions in air quality and temperature in North China. Contributions of soil Nr emissions to O3 and secondary pollutants are revealed, exceeding effects of soil NOx or HONO emission. Soil Nr emissions play an important role in mitigating O3 pollution and addressing climate change.

The interaction between the sources and molecular compositions of humic-like substances (HULIS) at Nanjing, China, was explored. Significant fossil fuel source contributions to HULIS were found in the 14C results from biomass burnng and traffic emissions. Increasing biogenic secondary organic aerosol (SOA) products and anthropogenic aromatic compounds were detected in summer and winter, respectively.

We introduced an online method to simultaneously determine the content of inorganic salt ions and reactive oxygen species (ROS) in PM2.5 hour by hour. We verified the accuracy and precision of the instrument. And we got the daily changes in ROS and the main sources that affect ROS. This breakthrough enables the quantitative assessment of atmospheric particulate matter ROS at the diurnal scale, providing an effective tool to study sources and environmental impacts of ROS.

We attempt to understand the current state of East Asian organic aerosols with both the molecular marker approach and 14° C data of carbonaceous components. A significant positive correlation of nonfossil- and fossil-derived organic carbon with levoglucosan suggests the importance of biomass burning (BB) and coal combustion sources in the East Asian outflow. Thus, attribution of ambient levoglucosan levels over the western North Pacific to the impact of BB emission may cause large uncertainty.

We performed a long-term investigation of ambient volatile organic compounds (VOCs) in an industrial area in Nanjing, China. Followed by alkanes, halocarbons and aromatics were the most abundant VOC groups. Vehicle-related emissions were the major VOC sources in the study area. Aromatic and alkene VOCs were responsible for most of the atmospheric reactions.

We introduce a two-wavelength method for brown C measurements with a modified Sunset carbon analyzer. We defined the enhanced concentrations and gave the possibility of providing an indicator of brown C. Compared with the strong local sources of organic and elemental C, we found that differences in EC mainly originated from regional transport. Biomass burning emissions significantly contributed to high differences in EC concentrations during the heavy biomass burning periods.

Short summary
This study provides a systematic analysis of the spatial variations, potential sources, and secondary formation mechanisms of low molecular weight amines in aerosols over the marginal seas of China. Amines in offshore aerosols were largely influenced by terrestrial emissions, substantially contributed by marine sources, and dominated by secondary formation, with two distinct major pathways (nitrate or sulfate-associated) identified for different amine species.
This study provides a systematic analysis of the spatial variations, potential sources, and...
