In this study, four nitro-polycyclic aromatic hydrocarbons (Nitro-PAHs), 1-nitropyrene (1-NP),2-nitrofluorene (2-NF), 9-nitroanthracene(9-NA) and 3-nitrofluoranthene (3-NFl) were quantified in particulate matter collected at six different functional area sites in Dongguan, China, between December 2010 and April 2011. The results showed that concentration levels of nitro-PAHs at the heavy traffic site (DaLing Shan) were higher than those at other sites. Nitro-PAHs were lower in winter than those in spring. Other atmospheric constituents, such as O3, NOx, NO2 were also recorded (not at all sampling sites) in order to investigate their correlations with nitro-PAHs concentrations. The results showed that 2-NF and 3-NFl were mostly presented positive correlation with NOx and NO2, but negative correlation with O3. There was no significant correlation between 1-NP, 9-NA and the O3, NOx and NO2.
