The results of comparing PM_10 concentration between ‘Namsan’ and ‘Yongsan-gu’ air
quality monitoring stations show similar values with averaged concentration in the whole
Seoul. The correlation factors in both sites were 0.865, 0.828 in 2005, 2006, respectively.
For ‘Bukhansan’ and ‘Gangbuk-gu’ air quality monitoring stations, different from the results
mentioned above, they showed clear differences as altitude changes. PM10 concentration in
‘Bukhansan’ monitoring stations was 10 mg/m^3 lower than ‘Gangbuk-gu’ monitoring station
which is located near the ground. Also, averaged PM10 concentration in ‘Bukhansan’ and
‘Gangbuk-gu’ monitoring stations was lower than that in the whole Seoul.
When comparing NO_2 concentration between ‘Namsan’ and ‘Yongsan-gu’ monitoring
stations, NO_2 concentration in ‘Namsan’ monitoring station was lower than ‘Yongsan-gu’
monitoring station.
For NO_2 concentration in ‘Bukhansan’, ‘Gangbuk-gu’ and ‘the whole Seoul’, there were the
same pattern in ‘Gangbuk-gu’ and the ‘the whole Seoul’ and low values in ‘Bukhansan’
monitoring station. The correlation factors of NO_2 concentration in ‘Bukhansan’ and ‘Gangbukgu’
was 0.525, 0.549 in 2005, 2006, respectively, which stands for low correlationship
