title: Effect of ferrous sulfate on parathion degradation in flooded soil.
abstract: In an isotope study, the effect of ferrous sulfate on the degradation of parathion was studied under flooded soil conditions. The addition of ferrous sulfate to flooded soil led to more rapid and extensive degradation of parathion with the formation of additional degradation products in ferrous sulfate-amended soil. This effect was not pronounced when ferrous sulfate was added to non-flooded soil or to flooded autoclaved soil. Sulfate, rather than Fe2+, was implicated in the extensive degradation of parathion.
