摘要：

A short term study of the chemical composition of rainwater was carried out from November 1999 to October 2000 in Singapore. The rainwater was typically acidic with a mean pH of 4.2. Sulfate was the most abundant ion and comparable to the results reported for other industrialized regions. The concentrations of major ions (NH4+, Ca2+ , K+, Na+, Mg2+, SO42+ NO32- Cl- HCOO-, CH3COO-) varied monthly. Results show that local meteorological conditions influence the chemical compositions to a significant extent. The pollutants in rainwater were derived from long range and local (industry and traffic) sources. (C) 2003 Elsevier Science Ltd. All rights reserved.
