Distribution of particulate- and vapor-phase n-alkanes and polycyclic aromatic hydrocarbons in urban atmosphere of Guangzhou, China
AbstractPolycyclic aromatic hydrocarbons (PAHs) are becoming a major component of atmospheric toxic pollutants (ATPs) in Guangzhou city, China. Studies showed that ATPs may have adverse health effect in urban area. An investigation on particulate- and vapor-phase distribution of n-alkanes and PAHs in urban atmosphere has been conducted. In LiWan district, 24h sampling for three consecutive days was performed in April and July 2001 at ground level. For comparison, samples were also collected on a nine-story building, ca. 25m above ground level. The ambient concentrations of ∑n-alkanes and ∑PAHs, compositional variations including molecular diagnostic ratios, natural biogenic and anthropogenic sources, as well as phase distributions of n-alkanes and PAHs are discussed. In addition, there are discernible differences with height, in terms of concentration and, to a lesser extent, in profiles of the compounds investigated.
