The photodegradation of chlorpyrifos-methyl (1), and two of its photodegradation products, chlorpyrifos-methyl oxon (2), and 3,5,6-trichloro-2-pyridinol (3) was studied using low pressure Hg lamps irradiating at 254 nm ...

Direct short-wave photolysis of chlorpyrifos-methyl (1) and chlorpyrifos-methyl oxon (2) was studied in the presence of native cyclodextrins (α–, β– and γ–CD) and randomly methylated β–CD (RAMEB). We used for irradiation ...

This work aimed for an elucidation of the mechanism of tropospheric decomposition of the organophosphorus pesticides chlorpyrifos and chlorpyrifos-methyl using calculations based on the density functional theory (DFT) with ...

To increase our understanding about the mode of toxic action of organophosphorus pesticides in earthworms, a microcosm experiment was performed with Aporrectodea caliginosa exposed to chlorpyrifos-spiked soils (0.51 and ...

"Background. The use of Chlorpyrifos leads to a public, environmental, and occupational health problem associated with adverse effects in the exposed population, generating alterations mainly in the central nervous system, ...

Acute effects of active ingredients (a.i.) andformulations (F) of widely used pesticides were assessedby means of the Daphnia magna toxicity test. Studiedpesticides were the insecticides, cypermethrin and chlorpyrifos,and ...

The biomixture is a principal element controlling the degradation efficacy of the biobed. The maturity of the biomixture used in the biobed affects its overall performance of the biobed, but this is not well studied yet. ...
