Particulate matter (PM) data collected from the Urban Air Monitoring Network in Busan during the period from 2006 through 2010 were statistically examined and analyzed to estimate the probability of exceeding PM2.5 24 hour and annual standard to be implemented from January 1st, 2015. For Jangrimdong, Yeonsandong, Kijangeup, and Jwadong where simultaneous measurement of PM10 and PM2.5 was conducted, the probability of exceeding PM2.5standards was estimated using PM2.5 data measured on site. For other areas where there were no measured PM2.5data available, the probability of exceeding PM2.5 standards was statistically estimated using PM10 measured on site and PM2.5/PM10 ratios obtained from the four stations where both PM2.5 and PM10 were monitored simultaneously.
At Jangrimdong, Yeonsandong, Kijangeup, and Jwadong, mean value of annual 99 percentile of 24 hr average PM2.5 for 5 years from 2006 through 2010 was 99.3, 74.5. 57.0, and 62.5 μg/m3, respectively, and the probability of exceeding PM2.5 24 hr standard was estimated at 100%. For areas where there were no measured PM2.5 data available,the estimated probability of exceeding PM2.5 24 hr standard was more than 0.82. Mean value of annual average PM2.5from 2008 through 2010 was 31.7 and 27.6 μg/m3 for Jangrimdong and Yeonsandong, respectively, which exceeded PM2.5 annual standard of 25 μg/m3. Mean value of annual average PM2.5 during the same period for Kijangeup and Jwadong was 19.2 and 20.7 μg/m3, respectively, which satisfied PM2.5 annual standard. For other areas where there were no measured PM2.5 data available, the probability of exceeding PM2.5 annual standard was more than 0.95except Taejongdae and Kwangahndong. With PM10 and PM2.5 data measured at 17 Urban Air Monitoring Stations in Busan, the probability of exceeding PM2.5 standards was estimated to be very high for almost all areas. This result indicates that proper measures to mitigate PM2.5 in Busan should be investigated and established as soon as possible.
