The study was carried out to evaluate the efficiencies of various remediation technologies (advanced oxidation processes and bioremediation) for removing diazinon and malathion residues from water. Nano photo-Fenton reagent (Fe(nano)/H2O2/UV) was the most effective treatment for diazinon and malathion removal while ultraviolet alone was the least effective one. Bioremediation of diazinon and malathion by effective microorganisms (EMs) removed about 100% of their initial concentration. There was no remaining toxicity in contaminated water after remediation except for ultraviolet alone on treated rats. Advanced oxidation processes with nanomaterials and bioremediation with effective microorganisms can be regarded as safe and effective remediation technologies.
