Numerous lakes are shrinking, owing to climate change and human activities, releasing pollutants from dried lake beds as dust aerosols. The health risks remain unclear. Recently, Poyang and Dongting lakes faced record droughts, exposing 99 % and 88 % of their areas. We show that lake bed dust can raise PM10 to 637.5 μg m-³ and exceed non-carcinogenic (HQ = 4.13) and Cr carcinogenic (approx. 2.10 × 10−⁶) risk thresholds, posing growing health threats.

Our results show that continental pollution and ocean emissions continuously mix, with chemical reactions producing new compounds. During polluted periods, nitrogen- and sulfur-containing molecules increased sharply. Notably, marine-derived signatures remained present even in winter, highlighting the ocean's persistent influence. This complexity affects how particles impact regional air quality, underscoring the need to consider both land and sea sources in environmental models.

Heatwaves worsen ozone and secondary organic aerosol pollution. We quantified how much comes from heat speeding up chemical reactions versus increasing natural emissions in China. High temperatures drive over 80 % of the pollution increase nationwide by making the atmosphere more chemically reactive. The effect was strongest in the Yangtze River Delta and Pearl River Delta. Limiting climate change is essential for controlling future pollution and protecting health.

Dust aerosols in the atmosphere often carry electric charges, which can change how they collide and grow. We measured these charges and found that electrical forces can speed up aerosol removal compared with traditional assumptions. This effect alters aerosol numbers and lifetimes and may influence air quality, cloud formation, and climate predictions.

Nitrogen dioxide is a common air pollutant that varies strongly across space and time, yet consistent global information has been limited. We developed a new global dataset that describes daily nitrogen dioxide levels from 2005 to 2023 by combining satellite observations, weather data, and ground measurements using artificial intelligence. The dataset reveals long-term changes and regional patterns and provides a reliable resource for future air quality research.

This study examines the impacts of reducing nitrogen oxides and volatile organic compounds on ozone (O3), secondary inorganic aerosols (SIAs), and OH and NO3 radicals. The results show similar predictions for 8 h O3 but significant variability for SIA and radicals, with differences up to 30 % for SIA and 200 % for radicals across chemical mechanisms and inventories. The findings highlight that evaluating control strategies for SIA and atmospheric oxidation capacity requires an ensemble approach.

In this study, we analyzed the mixing state and atmospheric chemical processes of Pb-rich single particles in Beijing. We focused on analyzing the differences in Pb-rich particles between the heating period and non-heating period, as well as the formation mechanism of lead nitrate after coal-to-gas conversion. Our results highlighted the improvement of Pb levels in the particulate as a result of coal-to-gas conversion.

Our study shows that the optical properties of brown carbon depend on its source. Brown carbon from ozone pollution had the weakest light absorption but the strongest wavelength dependence, while biomass burning brown carbon showed the strongest absorption and the weakest wavelength dependence. Nitrogen-containing organic carbon compounds were identified as key light absorbers. These results improve understanding of brown carbon sources and help refine climate models.

India is facing a severe air pollution crisis that poses significant health risks, particularly from PM2.5 and O3. Our study reveals rising levels of both pollutants from 1995 to 2014, leading to increased premature mortality. While anthropogenic emissions play a significant role, biomass burning also impacts air quality, in particular seasons and regions in India. This study underscores the urgent need for localized policies to protect public health amid escalating environmental challenges.

Numerical models are widely used in air pollution modeling but suffer from significant biases. The machine learning model designed in this study shows high efficiency in identifying such biases. Meteorology (relative humidity and cloud cover), chemical composition (secondary organic components and dust aerosols), and emission sources (residential activities) are diagnosed as the main drivers of bias in modeling PM2.5, a typical air pollutant. The results will help to improve numerical models.

In this study, we used a regional chemical transport model to characterize the different parameters of atmospheric oxidative capacity in recent chemical environments in China. These parameters include the production and destruction rates of ozone and other oxidants, the ozone production efficiency, the OH reactivity, and the length of the reaction chain responsible for the formation of ozone and ROx. They are also affected by the aerosol burden in the atmosphere.

Dust is a major source of atmospheric aerosols. Its chemical composition is often assumed to be similar to the parent soil. However, this assumption has not been rigorously verified. Dust aerosols are mainly generated by wind erosion, which may have some chemical selectivity. Mn, Cd and Pb were found to be highly enriched in fine-dust (PM2.5) aerosols. In addition, estimation of heavy metal emissions from dust generation by air quality models may have errors without using proper dust profiles.

The atmospheric age of particles reflects how long particles have been formed and suspended in the atmosphere, which is closely associated with the evolution processes of particles. An analysis of the atmospheric age of PM2.5 provides a unique perspective on the evolution processes of different PM2.5 components. The results also shed lights on how to design effective emission control actions under unfavorable meteorological conditions.

An updated version of the CMAQ model with biogenic volatile organic compound (BVOC) emissions from MEGAN was applied to study the impacts of different land cover inputs on O3 and secondary organic aerosol (SOA) in China. The estimated BVOC emissions ranged from 25.42 to 37.39 Tg using different leaf area index (LAI) and land cover (LC) inputs. Those differences further induced differences of 4.8–6.9 ppb in O3 concentrations and differences of 5.3–8.4 µg m−3 in SOA concentrations in China.

In China, the number of vehicles has jumped significantly in the last decade. This caused severe traffic congestion and aggravated air pollution. In this study, we developed a new temporal allocation approach to quantify the impacts of traffic congestion. We found that traffic congestion worsens air quality and the health burden across China, especially in the urban clusters. More effective and comprehensive vehicle emission control policies should be implemented to improve air quality in China.

Short summary
Brown carbon (BrC) aerosols absorb solar shortwave radiation and affect the environment and climate. Using a chemical transport model, we investigated the sources and long-term trends of primary BrC in China. Residential and industrial emissions dominate primary BrC in China, unlike the global pattern. Anthropogenic BrC accounts for most of the direct radiative effects and responds significantly to emission changes, indicating potential climate benefits of emission control measures.
