Abstract
|
|
|
The seasonal variation of pH and ion components in precipitation were investigated from January to December 2009 at
Busan, Korea. The precipitation was acidic with a volume-weighted mean pH concentration of 5.32, which ranged from 3.79 to 8.66. The volume-weighted mean conductivity showed 86.77 μS/cm and indicated higher concentration about 96.69 μS/츠 in summer. The volume-weighted mean equivalent concentration of components followed the order: K+ > Ca2+ > nss-Ca2+ >NH4+ > Mg2+ > Na+ > Li+ in cations and Cl- > SO42- > nss-SO42- > NO3
- > NO2- > F- > Br- in anions. Particularly, concentration of K+ and Cl- showed 56 and 78 % in cations and anions. The higher concentration in K+, Na+, Mg2+ and Cl- were shown in Busancity as compared to the other cities. The neutralization factors have been found to have higher value for potassium ion in winter compared with different seasons, indicating significant neutralization of acidic components over the region by potassium. Therefore, the precipitation characteristics at Busan had both continental and coastal as consequence of pH,conductivity and ionic analyses.
