Abstract
To investigate the characteristics of rainwater in Daegu area, parameters such as pH, electrical conductivity, TOC, TIC and TC were analyzed on 34 samples from January to December 2005. Results revealed that higher values were measured in winter than in summer. Furthermore samples that originated from industrial and commercial areas had higher chemical concentrations and conductivity as compared with those from residential and reference areas. Seldom acid-rain occurrence was recorded(27.2%) as compared with non-acid precipitation(72.8%) incidence. Also higher organic carbon fraction(TOC) was detected(72.5%) than inorganic form(TIC)(27.5%) in terms of component ratio with TC. During frequent rainfalls, the concentration of chemicals was decreased to a degree. Conversely, lower rate of rainfall gave out higher chemical values. Thereby the improvement of air qualify in 2005 compare with 2003 report was influenced by the environment authorities' efforts to reduce air pollutions and various factors by the depression of the region's economy.
