Wang Xiao’s 王晓 paper titled “Decadal Shifts in PAH Sources and Health Risks in China under Clean Air Actions” has been accepted for publication in Environmental Science & Technology (ES&T). The study integrates radiocarbon analysis of black carbon with positive matrix factorization to clarify long-term source-specific trends of polycyclic aromatic hydrocarbons (PAHs) across China. The findings reveal that while clean air actions significantly reduced coal combustion emissions, traffic-related PAHs have become an increasing contributor to toxicity and health risks, highlighting the need for further energy transition and vehicle electrification. Congratulations to Wang Xiao and the team on this important achievement!
On September 28, Buqing and Yifan’s mew paper entitled ‘ Elevated Wet Deposition of Micro- and Nano-plastics in Remote Mountains Driven by Free Tropospheric Transport‘ was accepted for publication in JHM. It has been a strong team work led by Shizhen. Bolong collected the samples; Yifan did the sample analysis and primary data curation, while Jianchu and He Kun helped with analytic practice; Buqing managed to write the manuscript, with Li Jing and Lingxiao helped with drawings and back trajectory analysis, etc. Congratulations!
On July 23, Li Jing’s new paper entitled ‘Advances in the Design of Urban CO2 Emission Monitoring Networks：A Review‘ was accepted for publication in Carbon Research. It is a nice and very useful review paper. Congratulations!
Figure 4. Global city-scale carbon emissions. The pink bars indicate city-wide atmospheric CO₂ enhancements relative to background levels (see Table 1), while the blue bars represent ¹⁴C-derived FFCO₂ emissions, the green bars represent differences between posterior (inversion) and prior (inventory) FFCO₂ emissions (see Table 3). The inversion results shown here are derived from well-documented urban CO2 monitoring networks that utilize tower-based or surface observations to support top-down validation of emission inventories. Dots mark the locations of global cities, overlaid on a colored background map showing fossil fuel CO₂ emissions in December 2022 from the ODIAC inventory (Open-source Data Inventory for Anthropogenic CO2)(Tomohiro & Shamil, 2015). The 14C-derived fossil fuel CO₂ including data from (W. J. Zhou et al., 2020) (Urumqi, Harbin, Guiyang, Lanzhou, Chongqing, Xi’an, Beijing, Wuhan), (Niu et al., 2016) (Xiamen), (Ding et al., 2013) (Guangzhou), (Sharma et al., 2023) (Indian), (Santos et al., 2019) (Rio de Janeiro), (Miller et al., 2020) (Los Angeles), (Turnbull et al., 2015) (Indianapolis), (Zazzeri et al., 2023) (London),(Lopez et al., 2013) (Paris), (Molnár et al., 2010) (Debrecen), (Levin & Rödenbeck, 2008) (Heidelberg), (Svetlik et al., 2010)(Bratislava, Prague), (Piotrowska et al., 2020) (Gliwice), (Zimnoch et al., 2012) (Krakow).
