GC/MS characterization of the enzymatically-generated degradation products. RI is the experimental Kovats retention index of the molecule and m/z is the mass-to-charge ratio of the base peak fragment detected for each molecule. The leaving group and the corresponding degradation product are emphasized in red. (a) Paraoxon-ethyl (CAS 311-45-5) led to 4-nitrophenol (CAS 100-02-7); (b) Parathion-ethyl (CAS 56-38-2) led to 4-nitrophenol (CAS 100-02-7); (c) Diazinon (CAS 333-41-5) led to 6-methyl-2-propan-2-yl-1H-pyrimidin-4-one (CAS 2814-20-2); (d) Fenitrothion (CAS 122-14-5) led to 3-methyl-4-nitrophenol (CAS 58864-63-4).
