Three brominated trihaloacetaldehydes (THAs), bromodichloroacetaldehyde, dibromochloroacetaldehyde and tribromoacetaldehyde, were identified, by gas chromatography-mass spectrometry, in ozonated and chlorinated aqueous fulvic acid solutions containing inorganic bromide. Mass spectra of these THAs were obtained in the electron-impact and positive chemical-ionization modes. The significance of the formation of brominated THAs on water quality and future disinfection by-product regulation is discussed.
