Direct analysis of hazardous organic chemicals in the environment by tandem mass spectrometry is described. Liquid and solid chemical wastes and residues from lyophilized aqueous solutions are volatilized directly into the ion source of a triple quadrupole instrument. All or most wet chemical and chromatographic separation steps are eliminated. Analysis of phthalates, aromatic hydrocarbons, chlorocarbons, phenols, amines, and carboxylic acids by functional group and molecular weight is accomplished by using the technique of collision activated dissociation and a series of 0.5-s neutral loss and parent ion scans under data system control on a triple quadrupole instrument. Both knowns and unknowns are characterized, detection limits are at the 10-100 ppb level, and the total analysis time per sample is typically only 25-30 min.
