Sulphur isotopic and chemical compositions of the natural waters in the Chuncheon area, Korea

Sulfur, oxygen, and hydrogen isotope compositions of precipitation in Seoul, South Korea

“…2). Similar mean pH values in Seoul and Chuncheon were obtained by Yu and Park (2004). However, the average values of pH are higher than the value reported in 2000 (4.7 ± 1.4 by Lee et al (2000)).…”

“…The meteoric water (rain and snow) samples in Seoul were acquired on the roof of a five-story building at the School of Earth and Environmental Sciences in the Seoul National University Campus. The referenced Chuncheon samples of meteoric water were collected at each precipitation event of Kangwon National University in Chuncheon from October, 2000 to July, 2001 (Yu and Park, 2004).…”

“…This area is surrounded by developed and developing mining industries and forested areas. The emissions of atmospheric pollutants from Chuncheon are relatively insignificant to emissions from domestic fossil fuel consumption (Yu and Park, 2004). The last referenced area is Chonju (Na et al, 1995), which has a few industrialized areas surrounded by agricultural fields (Fig.…”

“…Sulfur oxides mainly as SO 2 are among the major precursors of acid rain, and they are released through fossil ronmental alterations (Mizutani and Rafter, 1969;Nakai and Takeuchi, 1975;Nissenbaum, 1978;Nriagu et al, 1987;Ohizumi et al, 1991;Yu and Park, 2004). Also, there is a distinct difference in the sulfur isotope ratios of fossil fuels such as coal and petroleum.…”

“…Thus the sulfur isotopic and major element composition of rainwater along with meteorological information can be used to trace the sources of sulfur in precipitation, and to evaluate contributions from different sources (Krouse, 1980;Krouse and Case, 1981;Na et al, 1995;Yu and Park, 2004). In this case variation among sources must be isotopically significant and changes in isotopic composition during transport and transformation must be trivial.…”
