초록
In this study, gingko leaf were used which is to monitoring and investigation for air pollution assessment by passive sampler, because of these Gingko plants leaves are widely distribution the Korea. During the growth of plants leaves, assessment of air pollution levels and sources as well as bio-accumulation rate by exposure of PAHs from ambient air. Sixteen priority PAHs concentration in Gingko plant leaves for all site varied between 123 and 745 ng/n d.w. with an average concentration of 367 ng/n d.w. Overall, sixteen priority PAHs in Gingko plant leaves exhibited for spatial distribution of concentration levels the sequence industrial area (I) > intersection point (TI) > residential area (R) > in intersection contiguity residential area (TR) and the concentration level appeared by 468, 409, 363, 244 ng/n d.w. each other. Origin is suggested that petrogenic of gasoline and diesel emission with combustion of pyrogenic origin by multiple contamination origins. Average accumulation rates (AR) were calculated by growth time(exposure time) of gingko leaves in natural condition, and the results presented followed, residential area is average 44ng/g d.w/month, intersection is average 51ng/ g d.w/month, residential area of intersection surrounding is average28ng/g d.w/month, and industrial area average 56ng/g d.w/month, respectively.
Abstract
In this study, gingko leaf were used which is to monitoring and investigation for air pollution assessment by passive sampler, because of these Gingko plants leaves are widely distribution the Korea. During the growth of plants leaves, assessment of air pollution levels and sources as well as bio-accumulation rate by exposure of PAHs from ambient air. Sixteen priority PAHs concentration in Gingko plant leaves for all site varied between 123 and 745 ng/n d.w. with an average concentration of 367 ng/n d.w. Overall, sixteen priority PAHs in Gingko plant leaves exhibited for spatial distribution of concentration levels the sequence industrial area (I) > intersection point (TI) > residential area (R) > in intersection contiguity residential area (TR) and the concentration level appeared by 468, 409, 363, 244 ng/n d.w. each other. Origin is suggested that petrogenic of gasoline and diesel emission with combustion of pyrogenic origin by multiple contamination origins. Average accumulation rates (AR) were calculated by growth time(exposure time) of gingko leaves in natural condition, and the results presented followed, residential area is average 44ng/g d.w/month, intersection is average 51ng/ g d.w/month, residential area of intersection surrounding is average28ng/g d.w/month, and industrial area average 56ng/g d.w/month, respectively.
