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...
Haze in China has been increasing frequency of occurrence as well the area affected region. Here, we report on a new mechanism haze formation, which coexistence with NOx can reduce environmental capacity for SO2, leading to rapid conversion SO2 sulfate because NO2 and have synergistic effect when they react surface mineral dust. Monitoring data from five severe episodes January 2013 Beijing-Tianjin-Hebei regions agreed very laboratory simulation. The combined air pollution motor vehicle...
Abstract. The uncertainties of a national, bottom-up inventory Chinese emissions anthropogenic SO2, NOx, and particulate matter (PM) different size classes carbonaceous species are comprehensively quantified, for the first time, using Monte Carlo simulation. is structured by seven dominant sectors: coal-fired electric power, cement, iron steel, other industry (boiler combustion), (non-combustion processes), transportation, residential. For each parameter related to emission factors or...
We have developed multiple-year inventories of anthropogenic mercury emissions in China for 1995 through 2003. estimate that total Hg from all sources increased at an average annual rate 2.9% during the period 1995-2003, reaching 696 (+/- 307) t 2003, with a speciation split 395 Hg0, 230 Hg2+, and 70 Hg(p). Nonferrous metals smelting coal combustion continue to be two leading China, as nonferrous production consumption keep increasing. together contributed approximately 80% past decade. 202...
Abstract. Anthropogenic atmospheric emissions of typical toxic heavy metals have caused worldwide concern due to their adverse effects on human health and the ecosystem. By determining best available representation time-varying emission factors with S-shape curves, we establish multiyear comprehensive inventories 12 (Hg, As, Se, Pb, Cd, Cr, Ni, Sb, Mn, Co, Cu, Zn) from primary anthropogenic activities in China for period 1949–2012 first time. Further, allocate annual these 2010 at a high...
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. This paper presents a summary of the work done within European Union's Seventh Framework Programme project ECLIPSE (Evaluating Climate and Air Quality Impacts Short-Lived Pollutants). had unique systematic concept for designing realistic effective mitigation scenario short-lived climate pollutants (SLCPs; methane, aerosols ozone, their precursor species) quantifying its air quality impacts, this results in context overarching strategy. The first step was to create new emission...
The performances of fresh and sulfated MnOx-CeO₂ catalysts for selective catalytic reduction NOx by NH₃ (NH₃-SCR) in a low-temperature range (T < 300 °C) were investigated. Characterization these aimed at elucidating the role additive effect sulfation. catalyst having Sn:Mn:Ce = 1:4:5 molar ratio showed widest SCR activity improvement with near 100% conversion 110-230 °C. Raman X-ray photoelectron spectroscopy (XPS) indicated that Sn modification significantly increases concentration oxygen...
China is the largest contributor to global atmospheric mercury (Hg), and accurate emission inventories in are needed reduce large gaps existing Hg mass balance estimates assess effects on various ecosystems. The Atmospheric Mercury Emission (CAME) model was developed this study using probabilistic factors generated from abundant on-site measurements literature data. Using model, total anthropogenic emissions were estimated be continuously increasing 356 t 2000 538 2010 with an average annual...
Abstract. Nitrogen oxides (NOx) are key pollutants for the improvement of ambient air quality. Within this study we estimated historical NOx emissions in China period 1995–2010, and calculated future every five years until 2030 under six emission scenarios. Driven by fast growth energy consumption, estimate increased rapidly from 11.0 Mt 1995 to 26.1 2010. Power plants, industry transportation were major sources emissions, accounting 28.4%, 34.0%, 25.4% total 2010, respectively. Two...
Air quality was a vital concern for the Beijing Olympic Games in 2008. To strictly control air pollutant emissions and ensure good Games, municipal government announced an "Air Quality Guarantee Plan 29th Olympics Beijing". In order to evaluate effectiveness of guarantee plan, this study analyzed emission reductions during Olympiad Beijing. June 2008, daily SO2, NOX, PM10, NMVOC were 103.9 t, 428.5 362.7 890.0 respectively. During reduced 61.6 229.1 164.3 381.8 t −41%, 47%, 55%, 57% lower...
Abstract. Comprehensive field measurements are needed to understand the mercury emissions from Chinese power plants and improve accuracy of emission inventories. Characterization their behavior were measured in six typical coal-fired China. During tests, flue gas was sampled simultaneously at inlet outlet Selective Catalytic Reduction (SCR), electrostatic precipitators (ESP), desulfurization (FGD) using Ontario Hydro Method (OHM). The pulverized coal, bottom ash, fly ash gypsum also field....
China's past economic growth has substantially relied on fossil fuels, causing serious air pollution issues. Decoupling and become the focus in developing ecological civilization China. We have analyzed three-decade progress of controls China, highlighting a strategic transformation from emission control toward quality management. Emission sulfur dioxide (SO2) resolved deteriorating acid rain issue China 2007. Since 2013, actions multiple precursors sectors targeted reduction concentration...
Significance The Chinese government has taken efforts to tackle the nation’s severe ambient fine particle (PM 2.5 ) pollution. Our results suggest that reduced household solid-fuel consumption was leading contributor rapid decrease in integrated exposure and PM pollution during 2005–2015, even though there no explicit control policy. In contrast, emission reductions from power plants, industry, transportation contributed much less of exposure. Clean heating fuels have become part recent...
Abstract. Emissions of air pollutants in East Asia play an important role the regional and global atmospheric environment. In this study we evaluated recent emission trends sulfur dioxide (SO2), nitrogen oxides (NOx), particulate matter (PM), non-methane volatile organic compounds (NMVOC) Asia, projected their future emissions up until 2030 with six scenarios. The results will provide projections for modeling community model inter-comparison program (MICS-Asia). During 2005–2010, SO2 PM2.5...
Abstract. Emissions of hazardous trace elements in China are great concern because their negative impacts on local air quality as well regional environmental health and ecosystem risks. In this paper, the atmospheric emissions mercury (Hg), arsenic (As), selenium (Se) from coal combustion for period 1980–2007 estimated basis consumption data emission factors, which specified by different categories facilities, types, equipped pollution control devices configuration (Dust collectors, FGD,...
Mercury pollution control has become a global goal. The accurate estimate of long-term mercury emissions in China is critical to evaluate the budget and emission reduction potentials. In this study, we used technology-based approach compile consistent series China's atmospheric at provincial level from 1978 2014. totally emitted 13 294 t anthropogenic air during 1978–2014, which gaseous elemental mercury, oxidized particulate-bound accounted for 58.2%, 37.1%, 4.7%, respectively. removed...
