The Degradation of Organophosphorus Pesticides in Natural Waters: A Critical Review
Simo O. Pehkonen,Qi Zhang +1 more
TL;DR: In this article, the authors discuss the fate of organophosphorus pesticides in the aquatic environment via processes such as adsorption, hydrolysis, oxidation, and photochemical degradation.

Enzymatic hydrolysis of organophosphate insecticides, a possible pesticide disposal method.
TL;DR: Eight of 12 commonly used organophosphate insecticides were enzymatically hydrolyzed with this enzyme preparation at rates ranging from 12 to 1,360 nmol/min per mg of protein, whereas at higher concentrations they inhibited the reaction (9 to 50%).

Microbial decontamination of parathion and p-nitrophenol in aqueous media
TL;DR: A mixed microbial culture was adapted to growth on parathion to determine the feasibility of using microorganisms to detoxify concentratedParathion in agricultural wastes and the nitro group was removed in stoichiometric quantities as nitrite and hydroquinone was tentatively identified as a metabolite.

TL;DR: Results from gas chromatographic analysis suggested that Extracts of the two bacteria derived from organophosphate-grown cultures catalyzed the disappearance of Aspon, Azodrin, Dasanit, diazinon, malathion, Orthene, parathions, and Trithion but not dimethoate, Dylox, methyl parathion and Vapona.
Journal ArticleDOI
Understanding the degradation pathway of the pesticide, chlorpyrifos by noble metal nanoparticles.
TL;DR: Study shows that supported Ag and Au NPs may be employed in sustainable environmental remediation, as they can be used at room temperature in aqueous solutions without the use of additional stimulus such as UV light.

Rates of hydrolysis of carbamate and carbonate esters in alkaline solution
TL;DR: The data seemed to indicate two mechanisms for the hydrolysis of the carbamates: that initiated by an hydroxyl ion attachment on the central carbon atom followed by a carbamate ion intermediate, and that involving direct ionization of an amide hydrogen followed by formation of an isocyanate intermediate.
