Particle-associated polycyclic aromatic hydrocarbons in urban air of Hong Kong

TL;DR: In this paper, the concentrations of 16 selected polycyclic aromatic hydrocarbons (PAHs) in aerosols were quantified, and spatial and seasonal variations of PAHs were characterized.
Journal ArticleDOI

Risk assessment of exposure to volatile organic compounds in different indoor environments

TL;DR: The findings of this study show that the exposures to VOCs may lead to lifetime risks higher than 1 x 10(-6) and that people in a smoking home had the highest cancer risk, while students in an air-conditioned classroom had the lowest risk of cancer.
Journal ArticleDOI

Source apportionment of ambient non-methane hydrocarbons in Hong Kong: application of a principal component analysis/absolute principal component scores (PCA/APCS) receptor model.

TL;DR: A PCA/APCS model was applied to the data on non-methane hydrocarbons measured from January to December 2001 at two sampling sites in Hong Kong and found that vehicle emissions and LPG or natural gas leakage were the main sources of C(3)-C(5) alkanes and C( 3-C( 5) alkenes while aromatics were predominantly released from paints.
Journal ArticleDOI

Seasonal and diurnal variations of volatile organic compounds (VOCs) in the atmosphere of Hong Kong

TL;DR: The concentrations of VOCs in the atmosphere in Hong Kong were mainly affected by direct emissions from vehicles, evaporation of fuels, photochemical reactions and few industrial emissions.
