Summary: In this study, the contents of ten heavy metals in surface soil samples from the Pearl River Delta region were investigated. The results showed that the soil quality was generally good, with slightly elevated levels of certain heavy metals compared to background values. The source apportionment analysis revealed that the majority of soil heavy metals in the PRD region could be attributed to natural and industrial sources, with smaller contributions from transportation and agricultural activities.

Summary: Despite being banned for over three decades, organochlorine pesticides (OCPs) have not significantly decreased in concentration. This study in China's Pearl River Delta found that DDT had higher concentrations in summer than winter, chlordane showed less seasonal variation, and HCB was higher in winter. These findings indicate that geographic and anthropogenic factors, such as source, history, and air circulation pattern, play a significant role in the regional fate of OCP compounds.

Summary: Fugitive volatile organic compound (VOC) emissions from the petroleum-refining industry constitute a complex issue in China. Process-based leak detection and repair (LDAR) surveys have been shown to effectively reduce VOC emissions. This study evaluated the effectiveness of LDAR surveys in a local petroleum refinery in China and investigated the process-based fugitive emission characteristics. Results showed that establishing a local LDAR system should be the key strategy for future VOC emission reduction in the industry.

Summary: China has become the world leader in crude oil processing capacity in 2021. However, the petroleum refining industry generates significant VOC emissions, and the understanding of VOC emissions in this industry is still limited. This study systematically evaluated the historical emissions and reduction of VOCs in the petroleum refining industry in Guangdong, China's major province for crude oil processing, from 2001 to 2020. The results showed that VOC emissions followed an increasing-then-decreasing trend, with storage tanks and wastewater treatment as the largest sources. Efforts to reduce VOC emissions have shown positive results.

Summary: This study developed a novel meteorologically adjusted inversion method based on Ensemble Kalman filter (EnKF) to improve daily emission estimations. By combining sensitivity analysis and bias correction, the method alleviates inversion biases caused by meteorological input errors. A case study on carbon monoxide (CO) emissions in Pearl River Delta, China demonstrated that the new method significantly reduced daily variations of emissions and decreased the total amount of posterior CO emissions. Model evaluations showed that the emissions estimated by the method better reproduced the magnitude and temporal patterns of ambient CO concentration. The method is applicable to improve daily emission inversions of reactive pollutants as well.

Summary: This study developed the first nationwide on-road vehicular IVOC emission inventory in China based on localized measurement of the IVOC emission factors and volatility distributions for various vehicle types. The total vehicular IVOC emissions in China in 2019 were estimated to be 241.2 Gg. High-emission areas and hotspots were clearly identified by gridding the emission inventory into a relatively high resolution. Eastern China had substantially higher vehicular IVOC emissions than western China.

Summary: Due to the recent increase in ground-level ozone and volatile organic compounds (VOCs) emissions in China, controlling VOC emissions has become a major concern. This study proposes a framework for quantifying VOC emission caps constrained by PM2.5 and ozone targets, achieving cost savings in quantification. The results show that VOC emission caps vary greatly in the Pearl River Delta region based on NOx emission reductions, and different strategies can be adopted to meet air quality targets.

Summary: Multiple linear regression models are used to assess the contributions of meteorology/climate and anthropogenic emission control to linear trends of PM2.5 concentration in three regions in eastern China. The results indicate that the quantitative contributions derived from MLR alone are not credible, and there is a significant difference between short-term and long-term analyses. Long-term analysis provides a more precise assessment due to additional constraints from long-term data.

Summary: Vehicular emissions are a significant source of volatile organic compounds (VOCs) in urban and downwind areas. This study examined VOC emissions from vehicles using gasoline, diesel, and LPG as fuel. The results showed that emission factors of VOCs decrease with improved emission standards for gasoline vehicles, while variations in emission factors for diesel vehicles are more diverse. Cold starts significantly affect VOC emissions from gasoline vehicles, but have less impact on diesel vehicles. Most VOC species, especially oxygenated VOCs (OVOCs) and heavier aromatics, have higher emission factors from diesel vehicles compared to gasoline vehicles. The study also highlighted the importance of quantifying OVOC species in diesel emissions.

Summary: An observation-based method (OBM) was used to investigate the sensitivity of ozone formation to precursors in Guangdong. The results showed that approximately 67% of the observation days were sensitive to NOx, approximately 20% were in the transitional regime sensitive to both NOx and VOC, and only approximately 13% were sensitive to VOC. These findings differed from previous studies, which suggested that limiting VOC emissions would be more effective in reducing ozone pollution in Guangdong.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.
