The wastestreams of four dye manufacturing facilities were analyzed for the presence of dyes, dye precursors and intermediates using a battery of mass spectrometric techniques. Wastewater samples were extracted and concentrated using liquid/liquid extraction and XAD-2 resin adsorption methodology. Priority pollution analysis was conducted using EPA Method 625. Extracts were also analyzed using direct on-column injection capillary gas chromatography/mass spectrometry and desorption ionization techniques including thermospray high performance liquid chromatography/mass spectrometry and fast atom bombardment mass spectrometry. Elemental formulas for unknown compounds present at levels above 100 ppb were derived from accurate mass measurements using high- resolution mass spectrometry. The combined analytical data identified 313 compounds in the various wastewater streams. Partial structural characterization was obtained for an additional 94 compounds. A total of 107 unknown compounds were also detected. Only nine priority pollutants were detected using standard EPA methodology. The identified compounds were searched for genotoxic potential using the Gene-Tox database and 32 of them were identified as having genotoxic properties. The most concentrated of these were: chlorotoluene, 149 ug/l; dioctyl phthalate, 104 ug/l; triphenyl, 99 ug/l; dichloroaniline, 77 ug/l; chloroaniline, 59 ug/l; methylbenzenesulfonamide, 51 ug/l; and trinitrophenol, 46 ug/l.
