主　　题：PAHs Snow Source - Distribution GC-MS - Hailuogou of Mt. Gongga 

摘      要：Snow samples were collected over a 3-year period from 2012 to 2014 at the Hailuogou glacier of Mountain Gongga(Mt. Gongga) and analyzed for 16 priority polycyclic aromatic hydrocarbons(PAHs) using Gas Chromatography–Mass Spectrometry(GC–MS). The results show that total average levels of the 16 PAHs ranged from 452 to 290 ng·L^(-1) with a possible declining trend from 2012 to 2014. Distances between the sampling sites and the emission sources were estimated at typically less than 500 km. The results suggest that the major source of PAHs was from coal combustion, while contributions from automobile exhaust played an important role in more recent years. This finding was in agreement with the characteristics of presence of local industry, residence, and recent development of tourism of the surrounding areas.
