〖Abstract〗The chemical characteristic of wet precipitation was studied at Mountain Baiyun, Guangzhou on the basis of monitoring data in 2006. The rainwater was typically acidic with a volumeweighted mean pH value of 4.26, which ranged from 3.04 to 6.41. 70.2% of the total samples had pH values less than 5.60. The percent contribution to anions for SO2-4 and NO-3 were 59.0% and 19.9% respectively. Ca2+ was the highest concentration among the total cations with a contribution of 46.4 %, while NH+4 presented 17.5%. Nearly 84.7% of the acidity of rainwater was neutralized by main alkaline cations, Ca2+ and NH+4.Enrichment factors of major ions were computed to assess possible sources of major ions. The results showed that SO2-4 and NO-3 were from anthropogenic activities, while Ca2+and K+ from crust sources.
