The gas/particle partitioning of nitro-polycyclic aromatic hydrocarbons (nPAHs) and oxy-PAHs (oPAHs) is pivotal to estimate their environmental fate. Simultaneously measured atmospheric concentrations of nPAHs and oPAHs in both gaseous and particulate phases at 18 sites in northern China make it possible to investigate their partitioning process in a large region. The gas/particle partitioning coefficients...
Gas and particle-phase polycyclic aromatic hydrocarbons (PAHs) were measured in air at a background site (Xiaolongmen), two rural village sites (Gubeikou and Donghe), and at an urban site (Beijing) in the North China Plain from September 2007 to August 2008. The annual average total PAH concentration in Donghe was 730.7±608.0ng/m 3 and 18.2, 3.0, and 1.8 times higher than Xiaolongmen, Gubeikou...
