摘要：Rain water (about 140 l), collected in suburban residential and downtown areas, was fractionated by column chromatography on Amberlite XAD-2 resin and silica gel. Trace amounts of organic compounds in rain water were identified by the use of a GC-MS-computer system combined with three-dimensional mass chromatography. Phthalate esters, polycyclic aromatic hydrocarbons, higher fatty acids and their esters, and other aromatic derivatives were identified with high reliability.
