摘要

As a group of ubiquitous contaminants in environment,polycyclic aromatic hydrocarbons (PAHs)in atmosphere can be formed and emitted by natural and anthropogenic combustion processes.In this paper,we selected some filter samples collected aboard the R/V DayangYihao in the year of 2007 and analyzed 15 USEPA priority control PAHs over Asian marginal seas and remote North Pacific Ocean,respectively.The results showed that particulate PAHs over marginal sea were higher than that over the remote North PacificOcean by a factor of ~5-10.The PAH composition profile over marginal Sea was in agreement with that emitted by the continental emission sources,however,different pattern was observed for the PAHs over the remote North Pacific Ocean.
