| 1 | Air quality management in China:Issues,challenges,and options显示文摘This article analyzed the control progress and current status of air quality,identified the major air pollution issues and challenges in future,proposed the long-term air pollution control targets,and suggested the options for better air quality in China.With the continuing growth of economy in the next 10-15 years,China will face a more severe situation of energy consumption,electricity generation and vehicle population leading to increase in multiple pollutant emissions.Controlling regional air pollution especially fine particles and ozone,as well as lowering carbon emissions from fossil fuel consumption will be a big challenge for the country.To protect public health and the eco-system,the ambient air quality in all Chinese cities shall attain the national ambient air quality standards (NAAQS) and ambient air quality guideline values set by the World Health Organization (WHO).To achieve the air quality targets,the emissions of SO 2,NOx,PM 10,and volatile organic compounds (VOC) should decrease by 60%,40%,50%,and 40%,respectively,on the basis of that in 2005.A comprehensive control policy focusing on multiple pollutants and emission sources at both the local and regional levels was proposed to mitigate the regional air pollution issue in China.The options include development of clean energy resources,promotion of clean and efficient coal use,enhancement of vehicle pollution control,implementation of synchronous control of multiple pollutants including SO 2,NOx,VOC,and PM emissions,joint prevention and control of regional air pollution,and application of climate friendly air pollution control measures. | Shuxiao Wang Jiming Hao | 2012 | Journal of Environmental Sciences2012，24，1： | 71 |
| 2 | Ozone and secondary organic aerosol formation potential from anthropogenic volatile organic compounds emissions in China显示文摘Volatile organic compounds(VOCs) are major precursors for ozone and secondary organic aerosol(SOA), both of which greatly harm human health and significantly affect the Earth's climate. We simultaneously estimated ozone and SOA formation from anthropogenic VOCs emissions in China by employing photochemical ozone creation potential(POCP) values and SOA yields. We gave special attention to large molecular species and adopted the SOA yield curves from latest smog chamber experiments. The estimation shows that alkylbenzenes are greatest contributors to both ozone and SOA formation(36.0% and51.6%, respectively), while toluene and xylenes are largest contributing individual VOCs.Industry solvent use, industry process and domestic combustion are three sectors with the largest contributions to both ozone(24.7%, 23.0% and 17.8%, respectively) and SOA(22.9%,34.6% and 19.6%, respectively) formation. In terms of the formation potential per unit VOCs emission, ozone is sensitive to open biomass burning, transportation, and domestic solvent use, and SOA is sensitive to industry process, domestic solvent use, and domestic combustion. Biomass stoves, paint application in industrial protection and buildings,adhesives application are key individual sources to ozone and SOA formation, whether measured by total contribution or contribution per unit VOCs emission. The results imply that current VOCs control policies should be extended to cover most important industrial sources, and the control measures for biomass stoves should be tightened. Finally,discrepant VOCs control policies should be implemented in different regions based on their ozone/aerosol concentration levels and dominant emission sources for ozone and SOA formation potential. | WenJing Wu Bin Zhao Shuxiao Wang Jiming Hao | 2017 | Journal of Environmental Sciences2017，29，3： | 38 |
| 3 | Progress of Air Pollution Control in China and Its Challenges and Opportunities in the Ecological Civilization Era显示文摘China’s past economic growth has substantially relied on fossil fuels,causing serious air pollution issues.Decoupling economic growth and pollution has become the focus in developing ecological civilization in China.We have analyzed the three-decade progress of air pollution controls in China,highlighting a strategic transformation from emission control toward air quality management.Emission control of sulfur dioxide(SO2)resolved the deteriorating acid rain issue in China in 2007.Since 2013,control actions on multiple precursors and sectors have targeted the reduction of the concentration of fine particulate matter(PM2.5),marking a transition to an air-quality-oriented strategy.Increasing ozone(O3)pollution further requires O3 and PM2.5 integrated control strategies with an emphasis on their complex photochemical interactions.Fundamental improvement of air quality in China,as a key indicator for the success of ecological civilization construction,demands the deep de-carbonization of China’s energy system as well as more synergistic pathways to address air pollution and global climate change simultaneously. | Xi Lu Shaojun Zhang Jia Xing Yunjie Wang Wenhui Chen Dian Ding Ye Wu Shuxiao Wang Lei Duan Jiming Hao | 2020 | Engineering2020，6，12： | 24 |
| 4 | Efectiveness of national air pollution control policies on the air quality in metropolitan areas of China显示文摘Understanding the efectiveness of national air pollution controls is important for control policy design to improve the future air quality in China. This study evaluated the efectiveness of major national control policies implemented recently in China through a modeling analysis. The sulfur dioxide(SO2) control policy during the 11th Five Year Plan period(2006–2010) had succeeded in reducing the national SO2emission in 2010 by 14% from its 2005 level, which correspondingly reduced ambient SO2and sulfate(SO4 2) concentrations by 13%–15% and 8%–10% respectively over east China. The nitrogen oxides(NOx) control policy during the 12th Five Year Plan period(2011–2015) targets the reduction of the national NOx emission in 2015 by 10% on the basis of 2010. The simulation results suggest that such a reduction in NOx emission will reduce the ambient nitrogen dioxide(NO2), nitrate(NO3), 1-hr maxima ozone(O3) concentrations and total nitrogen deposition by 8%, 3%–14%, 2% and 2%–4%, respectively over east China. The application of new emission standards for power plants will further reduce the NO2, NO3, 1-hr maxima O3concentrations and total nitrogen deposition by 2%–4%, 1%–6%, 0–2% and 1%–2%, respectively. Sensitivity analysis was conducted to evaluate the inter-provincial impacts of emission reduction in Beijing-Tianjin-Hebei and the Yangtze River Delta, which indicated the need to implement joint regional air pollution control. | Shuxiao Wang Jia Xing Bin Zhao Carey Jang Jiming Hao | 2014 | Journal of Environmental Sciences2014，26，1： | 22 |

| 6 | Moving object detection in aerial video based on spatiotemporal saliency显示文摘In this paper,the problem of moving object detection in aerial video is addressed.While motion cues have been extensively exploited in the literature,how to use spatial information is still an open problem.To deal with this issue,we propose a novel hierarchical moving target detection method based on spatiotemporal saliency.Temporal saliency is used to get a coarse segmentation,and spatial saliency is extracted to obtain the object's appearance details in candidate motion regions.Finally,by combining temporal and spatial saliency information,we can get refned detection results.Additionally,in order to give a full description of the object distribution,spatial saliency is detected in both pixel and region levels based on local contrast.Experiments conducted on the VIVID dataset show that the proposed method is effcient and accurate. | Shen Hao Li Shuxiao Zhu Chengfei Chang Hongxing Zhang Jinglan | 2013 | Chinese Journal of Aeronautics2013，26，5： | 18 |
| 7 | Economic analysis of atmospheric mercury emission control for coal-fired power plants in China显示文摘Coal combustion and mercury pollution are closely linked, and this relationship is particularly relevant in China, the world's largest coal consumer. This paper begins with a summary of recent China-specific studies on mercury removal by air pollution control technologies and then provides an economic analysis of mercury abatement from these emission control technologies at coal-fired power plants in China. This includes a cost-effectiveness analysis at the enterprise and sector level in China using 2010 as a baseline and projecting out to 2020 and2030. Of the control technologies evaluated, the most cost-effective is a fabric filter installed upstream of the wet flue gas desulfurization system(FF + WFGD). Halogen injection(HI) is also a cost-effective mercury-specific control strategy, although it has not yet reached commercial maturity. The sector-level analysis shows that 193 tons of mercury was removed in 2010 in China's coal-fired power sector, with annualized mercury emission control costs of 2.7 billion Chinese Yuan. Under a projected 2030 Emission Control(EC) scenario with stringent mercury limits compared to Business As Usual(BAU) scenario, the increase of selective catalytic reduction systems(SCR) and the use of HI could contribute to 39 tons of mercury removal at a cost of 3.8 billion CNY. The economic analysis presented in this paper offers insights on air pollution control technologies and practices for enhancing atmospheric mercury control that can aid decision-making in policy design and private-sector investments. | Maria Pia Ancora Lei Zhang Shuxiao Wang Jeremy Schreifels Jiming Hao | 2015 | Journal of Environmental Sciences2015，27，7： | 15 |
| 8 | Evaluation of health benefit using Ben MAP-CE with an integrated scheme of model and monitor data during Guangzhou Asian Games显示文摘Guangzhou is the capital and largest city(land area:7287 km2)of Guangdong province in South China.The air quality in Guangzhou typically worsens in November due to unfavorable meteorological conditions for pollutant dispersion.During the Guangzhou Asian Games in November 2010,the Guangzhou government carried out a number of emission control measures that significantly improved the air quality.In this paper,we estimated the acute health outcome changes related to the air quality improvement during the 2010 Guangzhou Asian Games using a next-generation,fully-integrated assessment system for air quality and health benefits.This advanced system generates air quality data by fusing model and monitoring data instead of using monitoring data alone,which provides more reliable results.The air quality estimates retain the spatial distribution of model results while calibrating the value with observations.The results show that the mean PM_2.5concentration in November 2010 decreased by 3.5μg/m^3 compared to that in 2009 due to the emission control measures.From the analysis,we estimate that the air quality improvement avoided 106 premature deaths,1869 cases of hospital admission,and 20,026 cases of outpatient visits.The overall cost benefit of the improved air quality is estimated to be 165 million CNY,with the avoided premature death contributing 90%of this figure.The research demonstrates that Ben MAP-CE is capable of assessing the health and cost benefits of air pollution control for sound policy making. | Dian Ding Yun Zhu Carey Jang Che-Jen Lin Shuxiao Wang Joshua Fu Jian Gao Shuang Deng Junping Xie Xuezhen Qiu | 2016 | Journal of Environmental Sciences2016，28，4： | 13 |

| 11 | Gas-to-particle conversion of atmospheric ammonia and sampling artifacts of ammonium in spring of Beijing显示文摘PM2.5 and gaseous pollutants(SO2,HNO2,HNO3,HCl,and NH3) were simultaneously collected by Partisol- Model 2300 Sequential Speciation Sampler with denuder-filter pack system in the spring of 2013 in Beijing.Water-soluble inorganic ions and gaseous pollutants were measured by Ion Chromatography.Results showed that the concentrations of NH3,NH+ 4and PM2.5 had similar diurnal variation trends and their concentrations were higher at night than in daytime.The results of gas-to-particle conversion revealed that [NH3]:[NH+4] ratio was usually higher than 1; however,it was less than 1 and the concentration of NH+4 increased significantly during the haze episode,indicating that NH3 played an important role in the formation of fine particle.Research on the sampling artifacts suggested that the volatilization loss of NH+4 was prevalent in the traditional single filter-based sampling.The excess loss of HNO3 and HCl resulted from ammonium-poor aerosols and semivolatile inorganic species had severe losses in the clean day,whereas the mass of NH+ 4was usually overestimated during the single filter-based sampling due to the positive artifacts.Correlation analysis was used to evaluate the influence of meteorological conditions on the volatilization loss of NH+4.It was found that the average relative humidity and temperature had great effects on the loss of NH+4.The loss of NH+4 was significantly under high temperature and low humidity,and tended to increase with the increasing of absorption of gaseous pollutants by denuder.The total mass of volatile loss of NH+4,NO- 3and Cl- could not be ignored and its maximum value was 12.17 μg m-3.Therefore it is important to compensate sampling artifacts for semivolatile inorganic species. | WEI LianFang DUAN JingChun TAN JiHua MA YongLiang HE KeBin WANG ShuXiao HUANG XiaoFeng ZHANG YuanXun | 2015 | Science China Earth Sciences2015，58，3： | 11 |
| 12 | Spatial and temporal variation of haze in China from 1961 to 2012显示文摘The purpose of this study is to analyze the climatic characteristics and long-term spatial and temporal variations of haze occurrence in China. The impact factors of haze trends are also discussed. Meteorological data from 1961 to 2012 and daily PM10 concentrations from2003 to 2012 were employed in this study. The results indicate that the annual-average hazy days at all stations have been increasing rapidly from 4 days in 1961 to 18 days in 2012. The maximum number of haze days occur in winter(41.1%) while the minimum occur in summer(10.4%). During 1961-2012, the high occurrence areas of haze shifted from central to south and east regions of China. The Beijing-Tianjin-Hebei(Jing-Jin-Ji) region, Shanxi,Shaanxi, and Henan Province are the high occurrence areas for haze, while the Yangtze River Delta(YRD) and the Pearl River Delta(PRD) have become regions with high haze occurrences in the last 25 years. Temperature and pressure are positively correlated with the number of haze days. However, wind, relative humidity, precipitation, and sunshine duration are negatively correlated with the number of haze days. The key meteorological factors affecting the formation and dissipation of haze vary for high and low altitudes, and are closely related to anthropogenic activities. In recent years, anthropogenic activities have played a more important role in haze occurrences compared with meteorological factors. | Rui Han Shuxiao Wang Wenhai Shen Jiandong Wang Kang Wu Zhihua Ren Mingnong Feng | 2016 | Journal of Environmental Sciences2016，28，8： | 11 |
| 13 | Design and demonstration of a next-generation air quality attainment assessment system for PM_(2.5)and O_3显示文摘Due to the increasingly stringent standards, it is important to assess whether the proposed emission reduction will result in ambient concentrations that meet the standards. The Software for Model Attainment Test—Community Edition(SMAT-CE) is developed for demonstrating attainment of air quality standards of O3 and PM2.5. SMAT-CE improves computational efficiency and provides a number of advanced visualization and analytical functionalities on an integrated GIS platform. SMAT-CE incorporates historical measurements of air quality parameters and simulated air pollutant concentrations under a number of emission inventory scenarios to project the level of compliance to air quality standards in a targeted future year. An application case study of the software based on the U.S. National Ambient Air Quality Standards(NAAQS) shows that SMAT-CE is capable of demonstrating the air quality attainment of annual PM2.5and 8-hour O3 for a proposed emission control policy. | Hua Wang Yun Zhu Carey Jang Che-Jen Lin Shuxiao Wang Joshua S.Fu Jian Gao Shuang Deng Junping Xie Dian Ding Xuezhen Qiu Shicheng Long | 2015 | Journal of Environmental Sciences2015，27，3： | 11 |
| 14 | Development and case study of a science-based software platform to support policy making on air quality显示文摘This article describes the development and implementations of a novel software platform that supports real-time, science-based policy making on air quality through a user-friendly interface. The software, RSM-VAT, uses a response surface modeling(RSM) methodology and serves as a visualization and analysis tool(VAT) for three-dimensional air quality data obtained by atmospheric models. The software features a number of powerful and intuitive data visualization functions for illustrating the complex nonlinear relationship between emission reductions and air quality benefits. The case study of contiguous U.S.demonstrates that the enhanced RSM-VAT is capable of reproducing the air quality model results with Normalized Mean Bias < 2% and assisting in air quality policy making in near real time. | Yun Zhu Yanwen Lao Carey Jang Chen-Jen Lin Jia Xing Shuxiao Wang Joshua S.Fu Shuang Deng Junping Xie Shicheng Long | 2015 | Journal of Environmental Sciences2015，27，1： | 10 |
| 15 | A case study of development and application of a streamlined control and response modeling system for PM_(2.5)attainment assessment in China显示文摘This article describes the development and application of a streamlined air control and response modeling system with a novel response surface modeling-linear coupled fitting method and a new module to provide streamlined model data for PM_(2.5) attainment assessment in China.This method is capable of significantly reducing the dimensions required to establish a response surface model,as well as capturing more realistic response of PM_(2.5) to emission changes with a limited number of model simulations.The newly developed module establishes a data link between the system and the Software for Model Attainment Test—Community Edition(SMAT-CE),and has the ability to rapidly provide model responses to emission control scenarios for SMAT-CE using a simple interface.The performance of this streamlined system is demonstrated through a case study of the Yangtze River Delta(YRD) in China.Our results show that this system is capable of reproducing the Community Multi-Scale Air Quality(CMAQ) model simulation results with maximum mean normalized error < 3.5%.It is also demonstrated that primary emissions make a major contribution to ambient levels of PM_(2.5) in January and August(e.g.,more than50%contributed by primary emissions in Shanghai),and Shanghai needs to have regional emission control both locally and in its neighboring provinces to meet China's annual PM_(2.5)National Ambient Air Quality Standard.The streamlined system provides a real-time control/response assessment to identify the contributions of major emission sources to ambient PM_(2.5)(and potentially O_3 as well) and streamline air quality data for SMAT-CE to perform attainment assessments. | Shicheng Long Yun Zhu Carey Jang Che-Jen Lin Shuxiao Wang Bin Zhao Jian Gao Shuang Deng Junping Xie Xuezhen Qiu | 2016 | Journal of Environmental Sciences2016，28，3： | 9 |
| 16 | Mercury mass flow in iron and steel production process and its implications for mercury emission control显示文摘The iron and steel production process is one of the predominant anthropogenic sources of atmospheric mercury emissions worldwide. In this study, field tests were conducted to study mercury emission characteristics and mass flows at two iron and steel plants in China. It was found that low-sulfur flue gas from sintering machines could contribute up to41% of the total atmospheric mercury emissions, and desulfurization devices could remarkably help reduce the emissions. Coal gas burning accounted for 17%–49% of the total mercury emissions, and therefore the mercury control of coal gas burning, specifically for the power plant burning coal gas to generate electricity, was significantly important. The emissions from limestone and dolomite production and electric furnaces can contribute29.3% and 4.2% of the total mercury emissions from iron and steel production. More attention should be paid to mercury emissions from these two processes. Blast furnace dust accounted for 27%–36% of the total mercury output for the whole iron and steel production process. The recycling of blast furnace dust could greatly increase the atmospheric mercury emissions and should not be conducted. The mercury emission factors for the coke oven,sintering machine and blast furnace were 0.039–0.047 g Hg/ton steel, and for the electric furnace it was 0.021 g Hg/ton steel. The predominant emission species was oxidized mercury, accounting for 59%–73% of total mercury emissions to air. | Fengyang Wang Shuxiao Wang Lei Zhang Hai Yang Wei Gao Qingru Wu Jiming Hao | 2016 | Journal of Environmental Sciences2016，28，5： | 8 |
| 17 | Response surface modeling-based source contribution analysis and VOC emission control policy assessment in a typical ozone-polluted urban Shunde,China显示文摘To develop a sound ozone(O_3) pollution control strategy,it is important to well understand and characterize the source contribution due to the complex chemical and physical formation processes of O_3.Using the 'Shunde' city as a pilot summer case study,we apply an innovative response surface modeling(RSM) methodology based on the Community Multi-Scale Air Quality(CMAQ) modeling simulations to identify the O_3 regime and provide dynamic analysis of the precursor contributions to effectively assess the O_3 impacts of volatile organic compound(VOC) control strategy.Our results show that Shunde is a typical VOC-limited urban O_3 polluted city.The 'Jiangmen' city,as the main upper wind area during July 2014,its VOCs and nitrogen oxides(NO_x) emissions make up the largest contribution(9.06%).On the contrary,the contribution from local(Shunde) emission is lowest(6.35%) among the seven neighbor regions.The local VOCs industrial source emission has the largest contribution comparing to other precursor emission sectors in Shunde.The results of dynamic source contribution analysis further show that the local NO_x control could slightly increase the ground O_3 under low(10.00%) and medium(40.00%)reduction ratios,while it could start to turn positive to decrease ground O_3 under the high NO_x abatement ratio(75.00%).The real-time assessment of O_3 impacts from VOCs control strategies in Pearl River Delta(PRD) shows that the joint regional VOCs emission control policy will effectively reduce the ground O_3 concentration in Shunde. | Zhiqiang You Yun Zhu Carey Jang Shuxiao Wang Jian Gao Che-Jen Lin Minhui Li Zhenghua Zhu Hao Wei Wenwei Yang | 2017 | Journal of Environmental Sciences2017，29，1： | 7 |

| 20 | Nonlinear Random Motion Analysis of Coupled Heave-Pitch Motions of a Spar Platform Considering lst-Order and 2nd-Order Wave Loads显示文摘In this study, the coupled heave-pitch motion equations of a spar platform were established by considering 1st-order and 2nd-order random wave loads and the effects of time-varying displacement volume and transient wave elevation. We generated random wave loads based on frequency-domain wave load transfer functions and the Joint North Sea Wave Project(JONSWAP) wave spectrum, designed program codes to solve the motion equations, and then simulated the coupled heave-pitch motion responses of the platform in the time domain. We then calculated and compared the motion responses in different sea conditions and separately investigated the effects of 2nd-order random wave loads and transient wave elevation. The results show that the coupled heave-pitch motion responses of the platform are primarily dominated by wave height and the characteristic wave period, the latter of which has a greater impact. 2nd-order mean wave loads mainly affect the average heave value. The platform's pitch increases after the 2nd-order low frequency wave loads are taken into account. The platform's heave is underestimated if the transient wave elevation term in the motion equations is neglected. | Shuxiao Liu YougangTang Wei Li | 2016 | Journal of Marine Science and Application2016，15，2： | 5 |
