Particulate and gas-phase products from the atmospheric degradation of chlorpyrifos and chlorpyrifos-oxon

The phosphorothioate structure is highly present in several pesticides. However, there is a lack of information about its degradation process in air and the secondary pollutants formed. Herein, the atmospheric reactions of chlorpyrifos, one of the most world-used insecticide, and its main degradatio...

Herein, the atmospheric reactions of chlorpyrifos, one of the most world-used insecticide, and its main degradation product – chlorpyrifos-oxon – are described. The photo-oxidation under the presence of NOx was studied in a large outdoor simulation chamber for both chlorpyrifos and chlorpyrifos-oxon, observing a rapid degradation (Half lifetime
