1长江三角洲地区大气O3和PM10的区域污染特征模拟显示文摘以TRACE-P污染源资料及上海市地方排放清单为基础,采用Models-3/CMAQ环境空气质量模型和中尺度气象模式MM5,模拟研究了2001-01和2001-07长三角近地面二次污染物O3及PM10的浓度分布及输送状况,并以上海市国控点2001年冬、夏季各10 d的小时监测数据对模型进行了验证.验证结果显示,Models-3/CMAQ对O3和PM10的模拟结果与监测值的相关系数分别为0.77和0.52;一致性指数分别达到0.81和0.99.模型对O3小时最高浓度的估算偏低27%,标准偏差为-3.1%;对PM10小时平均浓度的估算偏低10%,标准偏差为46%.模型已具备再现和模拟长三角大气污染输送过程的能力,且误差落在可接受的范围之内.模拟结果显示,2001-07长三角区域16个主要城市中,有14个城市O3小时最大浓度超过国家二级标准,高浓度O3可覆盖苏南和浙北广大区域.2001-01泰州、扬州、南京、镇江、常州等城市受本地排放源和北部大气污染输送的影响显著,大气PM10日均浓度超过PM10国家二级标准.长三角地区环境空气质量与污染类型受大气污染传输与化学转化的影响十分明显.夏季太阳辐射较强时,南部城市排放的污染物常以二次污染物的形式影响下风向城市;太阳辐射较弱的情况下,则以一次污染物输送为主的形式影响周边地区.冬季长三角区域颗粒物污染总体水平较高,这与我国北方地区排放的颗粒物在西北风作用下向长三角输送造成的影响密切相关.长三角地区的大气污染已逐渐从局地转为区域问题.李莉 陈长虹 黄成 黄海英 李作攀 Joshua S.

2基于响应面模型的区域大气污染控制辅助决策工具研发显示文摘基于CMAQ模型结果,利用高维克里金插值算法,建立了排放控制因子与污染物环境浓度的响应面模型(RSM),实现了大气污染可控源排放与复合污染水平的实时函数响应.研究结果显示,RSM对PM2.5的预测结果与CMAQ实际模拟结果的误差在容许范围内(最大误差小于0.20μg.m-3,3.89%).基于所建立的RSM,开发了RSM-VAT区域大气污染控制可视化辅助决策工具.使用RSM-VAT对美国8个典型城市的PM2.5污染状况进行了控制情景分析,通过'可视化展示'和'图表分析'二大模块,输出不同控制情景下的环境污染物浓度的实时响应图、可视化展示和数据分析图表等结果.劳苑雯 朱云 Carey Jang Che Jen Lin 邢佳 陈志润 谢俊平 王书肖 Joshua Fu 2012环境科学学报2012,32,8:20
3Evaluation 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 2016Journal of Environmental Sciences2016,28,4:13
4应用Models-3/CMAQ研究长三角区域大气污染及输送显示文摘选用美国国家环保局第3代空气质量模式(Models-3,/CMAQ),配合中尺度气象模式(MM5)进行研究,模拟了2001年1、7月份长江三角洲区域冬夏季典型天气条件下大气层二次污染物臭氧及颗粒物的浓度分布及输送状况。采用2001年冬.夏季各10d的小时监测数据对模式验证。结果表明,Models-3/CMAQ对O3、PM10的模拟相关系数分别为0.77和052;一致性指数分别达到081和0.99。模型对于O3略微低估,标准偏差为-31%,而对于PM10则有所高估,标准偏差为46%。对长三角7月份O3浓度及1月份PM10的模拟结果显示,7月份长三角区域16个主要城市O3日均浓度集中在0.043~0.086mg/m^3之间,其中,泰州、扬州.湖州、镇江O3月日均浓度相对较高,均超过0.064mg/m3o模拟时段内O3最高小时浓度达0.276mg/m^3。1月份整个模拟区域PM10月日均浓度为O056mg/m^3,其中,南京市PM10日均浓度最高,达0.080mg/m^3模拟时段内PM10最高小时浓度达0.432mg/m^3研究表明,长三角地区存在明显的污染物输送现象,大气污染已经从局地污染转化为区域污染。李莉 陈长虹 黄海英 黄成 李作攀 Joshua S Fu Carey J Jang David G Streets 2007上海环境科学2007,26,4:11

11Operando Converting BiOCl into Bi_(2)O_(2)(CO_(3))_(x)Cl_(y) for Efficient Electrocatalytic Reduction of Carbon Dioxide to Formate显示文摘Bismuth-based materials(e.g., metallic, oxides and subcarbonate) are emerged as promising electrocatalysts for converting CO_(2) to formate. However, Bio-based electrocatalysts possess high overpotentials, while bismuth oxides and subcarbonate encounter stability issues. This work is designated to exemplify that the operando synthesis can be an effective means to enhance the stability of electrocatalysts under operando CO_(2)RR conditions. A synthetic approach is developed to electrochemically convert Bi^(O)Cl into Cl-containing subcarbonate(Bi_(2)O_(2)(CO_(3))_(x)Cl_(y)) under operando CO_(2)RR conditions. The systematic operando spectroscopic studies depict that BiOCl is converted to Bi_(2)O_(2)(CO_(3))_(x)Cl_(y) via a cathodic potential-promoted anion-exchange process. The operando synthesizedBi_(2)O_(2)(CO_(3))_(x)Cl_(y) can tolerate-1.0 V versus RHE, while for the wet-chemistry synthesized pure Bi_(2)O_(2)CO_(3),the formation of metallic Bio occurs at-0.6 V versus RHE. At-0.8 V versus RHE, Bi_(2)O_(2)(CO_(3))_(x)Cl_(y) can readily attain a FEHCOO-of 97.9%,much higher than that of the pure Bi_(2)O_(2)CO_(3)(81.3%). DFT calculations indicate that differing from the pure Bi_(2)O_(2)CO_(3)-catalyzed CO_(2)RR, where formate is formed via a *OCHO intermediate step that requires a high energy input energy of 2.69 eV to proceed, the formation of H COO-over Bi_(2)O_(2)(CO_(3))_(x)Cl_(y) has proceeded via a *COOH intermediate step that only requires low energy input of 2.56 eV.Huai Qin Fu Junxian Liu Nicholas M.Bedford Yun Wang Joshua Wright Peng Fei Liu Chun Fang Wen Liang Wang Huajie Yin Dongchen Qi Porun Liu Hua Gui Yang Huijun Zhao 2022Nano-Micro Letters2022,14,7:1
