             abstract = "Methyl parathion is one of the most toxic of the organophosphate 
                         insecticides. While this agent continues to be used, natural 
                         waters in agricultural areas are likely to contain significant 
                         amounts of the biocide, representing a threat to beneficial 
                         insects, freshwater organisms, birds and mammals. The 
                         electrochemical oxidation of methyl parathion in acidic medium has 
                         been studied using a boron-doped diamond (BDD)/Ti anode under 
                         galvanostatic current control. Chronoamperometry showed that 
                         significant oxidation of reference standard methyl parathion 
                         commenced at 1.8 V vs Ag/AgCl, while spectrophotometric studies 
                         revealed that the absorbance of a commercial formulation of the 
                         insecticide decayed according to time in electrolysis. 
                         Electrochemical degradation experiments were performed in a 
                         laboratory-constructed polypropylene cell in which solutions 
                         containing methyl parathion (equivalent to 60 mg L1) were 
                         subjected to electrolytic treatment at different current densities 
                         (5, 10, 25, 50 and 100 mA cm2). High performance liquid 
                         chromatographic analysis demonstrated that 81.2% of the 
                         insecticide was removed in 180 min at an applied current density 
                         of 100 mA cm2, and a compound, identified from its UV spectrum as 
                         4-nitrophenol, was formed either as an intermediate or as a 
                         byproduct. Under these conditions, mineralization efficiency 
                         (determined by total organic carbon analysis) was 67.6%, and the 
                         toxicity of the original electrolyte against the bioluminescent 
                         bacterium Vibrio fischeri was reduced considerably by the 
                         electrochemical treatment. It is concluded that electrooxidation 
                         using BBD/Ti electrodes represents an appropriate method for the 
                         removal of methyl parathion from contaminated waters.",
