Abstract

A new comprehensive analysis method has been developed for organic components in illegal dumping wastes, based on liquid chromatography-mass spectrometry (LC-MS). This study consists of two subjects: one is identification for not-specified substances and another quantitative analysis for specified substances. The 160 objective chemical substances were selected from a viewpoint of the distribution coefficient between water and octanol. Their mass spectra and retention times on LC-MS using an ODS column were stored in the data base for identification of unknown mass spectra. As quantitative analysis, analytical methods have been developed for several representative chemicals known as important hazardous compounds. This paper describes the analytical method for melamine as a typical example. Keywords: landfills, illegal dumping waste, hazardous wastes, LC-MS, database, melamine.
