2021年7月26日，清华大学地球系统科学系（简称“地学系”）张强教授课题组在《自然-地球科学》（Nature Geoscience）在线发表题为“2002–2017年中国大气细颗粒物污染及其健康影响变化的驱动力”（Drivers of PM2.5air pollution deaths in China 2002–2017）的论文，系统解析了2002–2017年间我国大气细颗粒物（PM2.5）污...
二元酸及其相关化合物是有机气溶胶(OA)的重要组成部分，能够为OA的来源提供证据。我院Chandra Mouli Pavuluri教授课题组研究了天津市夏、冬两季大气细颗粒物(PM2.5)，以期更好的了解华北地区OA的来源和二次生成机制。据观测结果发现，煤炭和生物质的燃烧、区域尺度的原位光化学反应以及远距离传输的老化气溶胶是夏、冬两季水溶性OA的主要来源。 本研究表明，液相环境下二元酸及其相关化合...
近年来，我国许多地区空气质量日益好转，但臭氧污染这一名词频频出现。国际期刊《自然·地球科学》15日在线发表了中美科学家联合研究成果，提出治理臭氧和PM2.5污染应采取协同控制策略，在减排NOx（氮氧化物）控制PM2.5污染的同时，需要有力地控制VOCs（挥发性有机化合物）排放来减缓臭氧污染。
Development of PM2.5 source impact spatial fields using a hybrid source apportionment air quality model
PM2.5 source spatial fields hybrid source apportionment air quality model

An integral part of air quality management is knowledge of the impact of pollutant sources on ambient concentrations of particulate matter (PM). There is also a growing desire to directly use source i...
A novel model evaluation approach focusing on local and advected contributions to urban PM2.5 levels – application to Paris, France
novel model evaluation approach focusing local and advected contributions urban PM2.5 levels application to Paris France
2014/12/19
Aerosol simulations in chemistry transport models (CTMs) still suffer from numerous uncertainties, and diagnostic evaluations are required to point out major error sources. This paper presents an orig...

Evaluation and application of a semi-continuous chemical characterization system for water soluble inorganic PM2.5 and associated precursor gases
Evaluation application semi-continuous chemical characterization system water soluble inorganic PM2.5
2010/2/8
Water soluble inorganic particles components (Cl−, SO42−, NO3−, and NH4+) and concentrations of their associated precursor gases (HCl, SO2, HNO3, NH3) were semi-continuously measured...
