Abstract

Photodecomposition of the herbicide bromofenoxim was studied in aqueous solution, solid state and in aerosol form. Zn all cases, bromoxyniland 2,4-dinitrophenol are the degradation products. Photodecomposition rate in solution is strongly dependent on the pH with a minimum at pH 8-10 and increasing at lower and higher pH values. Hydrolysis at pH 12 in darkness also yields 2,4-dinitrophenol and bromoxynil as products, while hydrolysis in acidic medium has not been observed to occur inabsence of light. Photodecomposition of solid bromofenoxim deposited on an inert surface is also studied and linked to the irradiation time. A system for generation of test aerosols is described. Dry and droplet aerosols are collected, extracted and analyzed after different times of irradiation in order to study the possible photolytical behaviourof bromofenoxim in the atmosphere.
