Carbonaceous and Ionic Components of Atmospheric Fine Particles in Beijing and Their Impact on Atmospheric Visibility
PM2.5 OC EC Ion Visibility
2016/3/25
Ground-based observation of fine particulate matter (PM2.5) in Beijing was carried out continuously in 2006. The
carbonaceous and ionic components, as well as their distribution characteristics and s...
Characteristics of Atmospheric Elemental Carbon (Char and Soot) in Ultrafine and Fine Particles in a Roadside Environment, Japan
Black carbon (BC) Ultrafine particles Char-EC Soot-EC Diesel exhausts
2016/3/28
Atmospheric carbonaceous components, particularly char and soot in ultrafine particles (UFPs; Dp < 0.1 m) and fine
particles (FPs; Dp < 2.5 m), were measured four times during one...
Analysis of Relationship between Inorganic Gases and Fine Particles in Cleanroom Environment
Diffusion denuder system (DDS) AMCs (Airborne Molecular Contaminants) Micro-contamination Cleanroom
2016/3/29
The concentrations and characteristics of major components in inorganic gases and fine particles were measured at the
photo and etch cleanroom areas in a Taiwan semiconductor factory. The results sho...
One-year record of organic and elemental carbon in fine particles in downtown Beijing and Shanghai
organic elemental carbon fine particles Beijing Shanghai
2009/2/11
Weekly PM2.5 samples were collected for one year (1999-2000) in Beijing and Shanghai and the carbonaceous species analyzed to investigate and compare their time series patterns and possible sources in...
Mass concentration and ion composition of coarse and fine particles in an urban area in Beirut: effect of calcium carbonate on the absorption of nitric and sulfuric acids and the depletion of chloride
Mass concentration effect of calcium carbonate absorption of nitric and sulfuric acids the depletion of chloride
2009/1/8
Levels of coarse (PM10-2.5) and fine (PM2.5) particles were determined between February 2004 and January 2005 in the city of Beirut, Lebanon. While low PM mass concentrations were measured in the rai...
Detecting charging state of ultra-fine particles: instrumental development and ambient measurements
ultra-fine particles instrumental development ambient measurements
2008/12/3
The importance of ion-induced nucleation in the lower atmosphere has been discussed for a long time. In this article we describe a new instrumental setup – Ion-DMPS – which can be used to detect contr...

Investigating the sources and atmospheric processing of fine particles from Asia and the Northwestern United States measured during INTEX B
2008/11/3
During the National Aeronautics and Space Administration (NASA) Intercontinental Chemical Transport Experiment, Phase B (INTEX-B), in the spring of 2006, airborne measurements were made in the United ...
The ozonolysis of primary aliphatic amines in fine particles
ozonolysis primary aliphatic amines
2008/10/31
The oxidative processing by ozone of the particulate amines octadecylamine (ODA) and hexadecylamine (HDA) is reported. Ozonolysis of these amines resulted in strong NO2– and NO3– ion signals that incr...
