The coupling of several analytical techniques Yia appropriate interfaces for monitoring selected organophosphorus pesticides (OPs) included in the EEC list of priority pollutants is illustrated. By utilizing positive and negative ion (PI and Nl, respectively) “filament on” tnermospray liquid chromatography-mass spectrometry (TSP LC-MS) and positive and negative chemical ionization (PCI and NCI, respectively) in direct liquid introduction (DLI) narrow-bore LC-MS, with acetonitrile-water mixtures, the characterization of several OPs is achieved. The use of 1% chloroacetonitrile in the LC mobile phase in DLI LC-MS is also discussed. Finally, reyersed-phase narrow-bore LC coupled to a thermionic detector (LC-TID) is carried out with methanol-water mixtures as eluent. Applications are reported for the determination of OPs in aquatic environments.
