The European Community has highlighted the problem of water pollution by pesticides. The need for validated mass spectrometric procedures for pesticides, lowering the risk of incorrect identification of the analyte with other techniques, has been underlined in a report from the Commission of the European Community (CEC). Regulations in EC countries require that the concentration of pesticides and related compounds should not exceed 0.1 μg/L for each individual substance. Considering these requirements, procedures for the GC-MS analysis of several pesticides are presented in this work. Samples for analysis, including Trichlorfon, Ethofumesate, Fenamiphos, and the products of their transformations, were selected among those indicated by the CEC as the priority pollutants with regard to the frequency of their use and the possibility of their leaching into ground water. A few compounds related to the selected pesticides are also considered. Furthermore, in several cases, transformation products and labeled analogues of the pesticides and their transformation products were synthesized to be used as internal standards with the aim of improving the accuracy of quantitative methods.
