초록

The paper studied PAHs concentrations deposited on pine needles (Pinus koraiensis) and Ginko tree leaves (Ginko biloba), which is used as a passive sampler of atmospheric PAHs, and calculated annual decrease rate of PAHs. It also estimated potential sources of ambient PHAs pollution in the semirural area of Anseong. Total concentrations of PAHs deposited on Ginko tree leaves (upto 287.5 ng/g dry) were 5.5 times higher than those on pine needles (upto 52.4 ng/g dry), but concentration distributions were very similar. PAHs concentrations deposited on tree leaves have decreased 5.5% (Ginko) ~ 7.9% (Pine) over 11 years (from 1998 to 2009). Diesel and gasoline burning vehicles and industry were expected main sources of PAHs.
