Air pollution exposure is associated with a range of adverse health impacts.Knowledge of the chemical components and sources of air pollution most responsible for these health effects could lead to an improved understanding of the mechanisms of such effects and more targeted risk reduction strategies.We measured daily ambient fine particulate matter(<2.5 microns in aerodynamic diameter; PM2.5)for two months in peri-urban and central Beijing,and assessed the contribution of its chemical components to the reactive oxygen species(ROS)-generating potential of ambient air pollution using the dithiothreitol(DTT)assay.

无锡地区2013 年11 月6 日至9 日经历了一次灰霾污染,10 日至13 日空气质量转为“良”.针对此次典型的污染过程,采用地基遥感大气颗粒物监测激光雷达,结合近地面颗粒物质量浓度(PM10,PM2.5)、大气碳黑浓度(BC)、大气成分(O3,SO2,NOx)对此次灰霾特征进行监测分析.地基大气颗粒物激光雷达的探测结果表明污染时段积聚在边界层内的颗粒物是导致本地空气质量恶化的重要因素(例如11
Since volatile organic compounds(VOCs)are important precursors of ozone(O3),identification and quantification of their emission sources are prerequisite for the formulation and implementation of O3 po
Haze pollution is most serious across winter in Beijing and contamination in 2012 heating period in winter was more serious than that in 2011.As coal combustion is an important source of haze particle
本文使用GEOS-Chem 来模拟全球主要人为污染源的远距离传输结果,并以CO 作为示踪气体探究O3 的传输路径,以区分O3 的传输过程与光化学反应过程,着重分析其他地区的人为污染源对我国O3传输贡献的季节变化和垂直分布。研究显示：欧洲人为排放所造成的O3传输主要影响我国35°N 以北地区,且在对流层低层浓度达到最高,O3 主要依靠西风带和边界层的水平传输影响我国；北美对我国的影响比欧洲偏南,由于
An eight-month record(2013,5-2013,12)of surface NO2 concentration from 184 urban automatic meteorological observation stations is used to analyzing characteristic of spatial and temporal NO2 distribut
Global chemical transport models(CTMs)are used extensively to study air pollution and transport at a global scale.These models are limited by coarse horizontal resolutions,not allowing for detailed re

本文采用室内土柱培养的方法,研究了温带成熟阔叶红松混交林和次生白桦林土壤在不同的湿度(55％和80％WFPS,土壤充水孔隙率)和不同的氮素供应(NH4Cl 和KNO3,4.5 g N m-2)条件下外源碳添加(葡萄糖,6.4 g C m-2)对森林土壤异养呼吸和微生物碳量的激发效应.结果表明：培养期间白桦林土壤对照处理二氧化碳(CO2)累积排放量(5.44～5.82 g CO2-C m-2)显著高
我国目前正面临着以臭氧(O3)为代表的光化学污染和以细颗粒物为代表的灰霾问题,而在海盐等颗粒物表面发生的非均相化学反应不仅可能影响二次有机气溶胶和无机气溶胶的生成,而且可能对生成臭氧的气相过程产生影响。因此,在烟雾箱中研究了以NaCl 为代表的海盐气溶胶在芳香烃和小分子VOC 光氧化生成O3 和二次有机气溶胶(SOA)中的作用机制。发现与不加种子颗粒物的实验相比,不同湿度条件下,引入NaCl 种子
The source-receptor(S-R)relationships of surface O3 over East Asia in 2010 were estimated by a 3-dimensional regional chemical transport model with an online tracer-tagged module.The model reproduced
