Abstract
|
|
|
East Asia is characterized by anthropogenic emissions resulting from the large population and fast economic growth of this region. Since the prevailing wind is westerly and northwesterly, emissions from Ul-jin can be expected to contribute to acidic deposition increase in downwind direction.
Aerosols collected at the near coast site, Uljin geun, gyungbook and were analyzed for NH4+, Mg2+, Na+, Ca2+, Cl-, SO42-, and NO3- from Aug. 2012 to Feb. 2013.
The seasonal averaged aerosol concentration showed the highest potassium and calcium ion in winter and the highest
ammonium ion due to a meadow and high solar intensity in summer. Sodium and chloride ion showed the same ratio all
seasons and sulfate and nitrate species showed the maximum value in winter
Chemical components of aerosols collected at the near coast site, Uljin geun, gyungbook were lower by 16 to 73% than
those collected at other similar environment site such as kanghwa, yangyang. Comparing air quality data at the near coast site, Uljin geun, gyungbook,
There was found that Uljin coast site is less influenced by the sea salts(potassium, magnesium, calcium) and nss-SO4
2- percentage is 3~13% higher than similar condition site.
