“…The latter was not observed in the mass spectrum, yet it could be responsible (through the loss of two OCH 3 groups) for the presence of the m/z 79 ion. It is worth noting that ions with m/z 63, 79, 93 and 141 have been observed in the EI spectrum of O,O,O-trimethylthiophosphate, 15 whose structure contains the fenthion fragments with m/z 125 and 141.…”

A solid-phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS) method for the simultaneous determination of the organophosphorus pesticides (OPPs), phorate, diazinon, methyl-parathion, fenitrothion, malathion, fenthion, ethyl-parathion and methidathion, has been developed to study their soil/water distribution. The method was used in conjunction with a conventional 'batch equilibrium method' to assess the soil adsorption coefficients (Koc) of the target compounds in different soil samples with known organic carbon content. Contrary to traditional techniques, the present method is fast, solvent-free and highly sensitive, thus permitting the assessment of the Koc values of the target compounds even at low soil concentration levels, close to those encountered in real field contamination, where the Freudlich adsorption isotherms can be considered to be linear. The estimated Koc values were found to be in good agreement with those reported in the literature.
