From 2013 to 2017, with the implementation of toughest-ever clean air policy in China, significant declines fine particle (PM2.5) concentrations occurred nationwide. Here we estimate drivers improved PM2.5 quality and associated health benefits China from 2017 based on a measure-specific integrated evaluation approach, which combines bottom-up emission inventory, chemical transport model, epidemiological exposure-response functions. The estimated national population-weighted annual mean...
Although much attention has been paid to investigating and controlling air pollution in China, the trends of air-pollutant concentrations on a national scale have remained unclear. Here, we quantitatively investigated variation pollutants China using long-term comprehensive data sets from 2013 2017, during which Chinese government made major efforts reduce anthropogenic emission polluted regions. Our results show significant decreasing trend PM2.5 concentration heavily regions eastern with...
Abstract. The mixing layer is an important meteorological factor that affects air pollution. In this study, the atmospheric height (MLH) was observed in Beijing from July 2009 to December 2012 using a ceilometer. By comparison with radiosonde data, we found ceilometer underestimates MLH under conditions of neutral stratification caused by strong winds, whereas it overestimates when sand-dust crossing. Using meteorological, PM2.5, and PM10 observational screened automatically; observations...
Abstract. The simultaneous observation and analysis of atmospheric fine particles (PM2.5) on a regional scale is an important approach to develop control strategies for haze pollution. In this study, samples filtered PM2.5 were collected simultaneously at three urban sites (Beijing, Tianjin, Shijiazhuang) background site (Xinglong) in the Beijing–Tianjin–Hebei (BTH) region from June 2014 April 2015. four was mainly comprised organic matter, secondary inorganic ions, mineral dust. Positive...
Abstract. The “Campaign on Atmospheric Aerosol Research” network of China (CARE-China) is a long-term project for the study spatio-temporal distributions physical aerosol characteristics as well chemical components and optical properties aerosols over China. This presents first data sets from this project, including 3 years observations online PM2.5 mass concentrations (2012–2014) 1 year compositions (2012–2013) CARE-China network. average concentration at 20 urban sites 73.2 µg m−3...
The air-pollution episodes in China January 2013 were the most hazardous Beijing-Tianjin-Hebei (BTH) region. PM 2.5 , AOD, and long-term visibility data, along with various climate meteorological factors boundary-layer structure, used to investigate cause of heavy-haze pollution events 2013. result suggests that unfavorable diffusion conditions (weak surface winds high humidity) primary-pollutant emissions have induced BTH region over past two decades. A sudden stratospheric warming (SSW),...
Abstract Based on a network of field stations belonging to the Chinese Academy Sciences (CAS), Campaign Atmospheric Aerosol Research China (CARE-China) was recently established as country’s first monitoring for study spatiotemporal distribution aerosol physical characteristics, chemical components, and optical properties, well gaseous precursors. The comprises 36 in total adopts unified approach terms instrumentation, experimental standards, data specifications. This ongoing project is...
Exosomes contain cell- and cell-state-specific cargos of proteins, lipids, nucleic acids play significant roles in cell signaling cell-cell communication. Current research into exosome-based biomarkers has relied largely on analyzing candidate biomarkers, i.e., specific proteins or acids. However, this approach may miss important that are yet to be identified. Alternative approaches analyze the entire exosome system, either by "omics" methods techniques provide "fingerprints" system without...
Ammonia (NH3) emission inventories are an essential input in chemical transport models and helpful for policy-makers to refine mitigation strategies. However, current estimates of Chinese NH3 emissions still have large uncertainties. In this study, improved inversion estimation China has been made using ensemble Kalman filter the Nested Air Quality Prediction Modeling System. By first assimilating surface observations from Monitoring Network at a high resolution 15 km, our results provided...
Gaseous nitrous acid (HONO) is a crucial precursor of the hydroxyl (OH) radical, which "detergent" in atmosphere. Nowadays, HONO formation mechanisms at polluted urban areas are controversial, restricts understanding atmospheric oxidative capacity and radical cycling. Herein, multiday vertical observation NOx was simultaneously performed three heights area Beijing for first time. The distribution often unexpected, it had highest concentration 120 m, followed by those 8 240 m. 0D box model...
