“…To better demonstrate the vanadium emissions conditions, the emissions of copper (Cu), zinc (Zn), and lead (Pb) from anthropogenic sources were selected as a reference. As for vanadium emissions from natural sources, it has been discussed in detail in our previous study . Basically, our estimates of total anthropogenic vanadium emissions had a consistent trend with other inventories, and the variations among different studies mainly originated from the evolution of oil quality. , As depicted in Figure E, owing to the phase out of leaded petrol in China after 2001, our study presented consistent trajectories with NAEI for four trace element emissions in 2005 and 2010, whereas there were larger discrepancies in the estimates of emission values because of differences in activity levels and emission factors between the two countries.…”

“…In this study, various emission sources of vanadium were divided into 6 major categories and 18 subcategories. Notably, natural sources were incorporated into this comprehensive emission inventory analysis considering their non-negligible contributions to vanadium emissions . The provincial-level activity data of fuel combustion were mainly retrieved from China Energy Statistical Yearbook .…”

Vanadium is a strategically important metal in the world, although sustained exposure under high vanadium levels may lead to notable adverse impact on health. Here, we leverage a bottom-up approach to quantitatively evaluate vanadium emissions from both anthropogenic and natural sources during 1949−2017 in China for the first time. The results show that vanadium emissions increased by 86% from 1949 to 2005 to a historical peak value and then gradually decreased to 12.9 kt in 2017. With the effective implementation of air pollution control measures, vanadium emissions from anthropogenic sources decreased sharply after 2011. During 2011−2017, about half of vanadium emissions came from coal and oil combustion. In addition, industrial processes and natural sources also cannot be ignored, with the total contributions of more than 24%. The high levels of vanadium emissions were mainly distributed throughout the North China Plain and the eastern and coastal regions, especially in several urban agglomerations. Furthermore, the comprehensive evaluation by incorporating contrastive analysis, Monte Carlo approach, and GEOS-Chem simulation shows that vanadium emissions estimated in this study were reasonable and acceptable. The findings of our study provide not only a scientific foundation for investigating the health effects of vanadium but also useful information for formulating mitigation strategies.

“…Anthropogenic emissions over mainland China for CMAQ simulations are derived from the Multiresolution Emission Inventory for China (MEIC) developed by Tsinghua University () and the TE emission inventory established in this study. Emissions from the surrounding countries rather than China in the domain are filled with data generated from the MIX Asian emission inventory for 2010 and the global TE emission inventory established by Zhu et al Natural source emissions such as soil and wind-erosion, dust, and biogenic emissions are derived from the emission inventory developed by Wu et al TE emissions are assigned a size (accumulation mode and coarse mode) in the CMAQ model based on measurement analysis in ambient sampling and source-testing experiments. − The model result is the sum of TE concentrations in particle sizes ≤2.5 μm in diameter (accumulation mode) and particle sizes between 2.5 and 10 μm in diameter (coarse mode).…”

Airborne trace elements (TEs) pose a notable threat to human health due to their toxicity and carcinogenicity, whereas their exposures and associated health risks in China remain unclear. Here, we present the first nationwide assessment of spatiotemporal exposure to 11 TEs in China by coupling a bottom-up emission inventory with a modified CMAQ model capable of TE simulation. Associated health risks of 11 TEs are then evaluated using a set of risk assessment models. Our results show that the CMAQ model could reasonably reproduce the spatiotemporal variations of 11 TEs in China compared to observations. We find significant but spatiotemporal-heterogeneous cancer risks associated with high-level exposure of TEs in China. Gridded cell concentrations of hexavalent chromium, arsenic, and nickel in eastern and central China usually exceed China’s air quality standard limits, resulting in significant cancer risks that affected over 85% of the entire population in China in 2015. National annual mean population-weighted concentrations of 11 TEs decrease by 9.8–35.6% from 2012 to 2015, largely attributed to emission reduction from coal combustion. Our study provides critical insights for policymakers to implement stricter measures to alleviate health burdens and benefit relevant epidemiological research on airborne TEs.

Volatile organic compounds (VOCs) are gases that are emitted into the air from products or processes and are major components of air pollution that significantly deteriorate air pollution and seriously affect human health. Different types of metals, metal oxides, mixed‐metal oxides, polymers, activated carbons, zeolites, MOFs and mixed‐matrixed materials have been developed and used as adsorbent or catalysts for diversified VOC capture, removal, and destruction. In this comprehensive review, we first discuss the general classification of VOC removal materials and processes and outline the historical development of bifunctional and cooperative adsorbent‐catalysts for the removal of volatile organic compounds (VOCs) from air. Subsequently, particular attention is devoted to design strategies for cooperative adsorbent‐catalysts, along with detailed discussions on the latest advances on these bifunctional materials, reaction mechanisms, long‐term stability, and regeneration for VOCs removal processes. Finally, challenges and future opportunities for the environmental implementation of these bifunctional and cooperative adsorbent‐catalysts are identified and outlined with the intent of providing insightful guidance on the design and fabrication of more efficient materials and systems for VOCs removal in the future.
