Published in ELSEVIER in AMSTERDAM ,Authors: Bianco, A; Sordello, F; Ehn, M; Vione, D; Passananti, M. The CAS is 93-97-0. Through research, I have a further understanding and discovery of Benzoic anhydride
Microplastics (MPs) and nanoplastics (NPs) are ubiquitous and contaminate soil, surface waters, atmospheric aerosol, precipitations, indoor and outdoor environments. However, the occurrence, transformation and fate of NPs in the environment are still unclear. In this work, polystyrene nanoparticles (PS-NPs) are used as a proxy of NPs to study their reactivity and potential impact on atmospheric and surface waters. In particular, the reactivity with hydroxyl radicals (center dot OH) in the aqueous phase is investigated. For the first time, a reactivity constant for the reaction of NPs with center dot OH is measured, strongly dependent on the exposed partide surface area of NPs. Degradation products (short chain carboxylic acids and aromatic compounds), obtained by direct and center dot OH-mediated photolysis of PS-NPs suspensions, are identified by mass spectrometry. Irradiation of a PS-NPs suspension under natural sunlight for 1 year has shown the formation of formic acid and organic compounds similar to those found in riverine and cloud dissolved organic matter, which could contribute significantly to the dissolved organic matter in the aqueous phase.
