Abstract
Particle associated PAHs were monitored in Baekryoung Island, the westernmost part of Korea, from August, 2003 to April, 2005. Monitoring station was carefully selected for detecting the real signal for atmospheric PAHs in the marginal Yellow Sea. Concentration of total suspended particulates (TSP) varied from 0.005 mg/m3 to 0.333 mg/m3. In the Asian Dust (AD) period, average TSP concentration showed the five times higher than the other periods. Sum of 16 PAHs ranged from 0.086 ng/m3 to 23.2 ng/m3 with average concentration of 4.09 ng/m3. Seasonal variation was observed and average PAHs concentration was in the order of winter (7.89 ng/m3) >> spring (3.13 ng/m3) > autumn (2.44 ng/m3) > summer (0.57 ng/m3). There was no correlation between TSP and total PAHs, implying that particle composition rather than the amount of particle is the major factor. In winter, PAH concentration normalized by TSP reaches 466 ug/g. Among meteorological parameters, temperature and wind direction, i.e., low temperature and westerly wind are well correlated with winter time high PAH concentrations. Source recognition index using indeno(1,2,3-cd)pyrene and benzo[ghi]perylene indicated that coal burning is major source of PAHs in this region except summer. Major heating fuel consumption in China relies on coal and PAH produced by incomplete combustion of coal is thought to be transported to the nearby Yellow Sea and western part of Korea.
