The aim of this project is to study the degradation by ozonation of clothianidin, a compound of environmental concern. Concretely, the study is focused on investigate the kinetics of direct and indirect pesticide removal, which depend on hydroxyl radical (indirect way) and ozone directly (direct way), to obtain the second order rate constants of the degradation reactions. IIn addition, and because MPs are not mineralized but transformed into other chemical species, it is important to know which are these products and which risks could they pose because of their presence in the aquatic environment. Being so, preliminary studies on the degradation mechanisms and ecotoxicity screening were also performed in this work
