In this study, an acid precipitation monitoring network was set up to investigate the characteristics of contamination and sources in rainwater in Taoyuan County, Taiwan. Wet-only precipitation samples were collected from February 1994 to January 1995. Mean pH ranging from 3.21 to 4.49 is observed in Taoyuan County and reveals that rainwater acidification is indeed severe in this region. Sulfate is the dominant chemical component (153.5 mu eql(-1)) and follow by Cl- (133.4), Na+ (96.0) and NH4+ (80.9). Source apportionment of soluble ions with marine and crustal origins is calculated from the analysis of neutralization capacity factor and enrichment factor. The implications of results are discussed.
