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...
Nanoparticles in boreal forest and coastal environment: a comparison of observations and implications of the nucleation mechanism
Nanoparticles boreal forest coastal environment the nucleation mechanism
2010/8/16
The detailed mechanism of secondary new particle formation in the atmosphere is still under debate. It is proposed that particle formation happens via activation of 1–2 nm atmospheric neutral molecula...

Ozone reservoir layers a coastal environment southern Taiwan
2010/8/12
The air layer between the nocturnal boundary layer and the top of the daily mixing layer in an ozone-polluted area is known to serve as an ozone reservoir since the ozone that is produced in the mixin...
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...
The exchange of SVOCs across the air-sea interface in Singapore's coastal environment
SVOCs air-sea interface Singapore's coastal environment
2010/2/21
Coastal areas are vulnerable to the accumulation of semivolatile organic compounds, such as PAHs, OCPs and PCBs from atmospheric inputs. Dry particulate and wet depositions, and air-water diffusive ex...
A Comparative Study of Air Quality Index Based on Factor Analysis and US-EPA Methods for an Urban Environment
Eclipsing effect Maximum operator concept (MOC) Principal component analysis (PCA) Variance, Ranking
2016/3/29
There are many different air quality indexes, which represent the global urban air pollution situation.
Although the index proposed by USEPA gives an overall assessment of air quality, it does not in...
