due to their potential risk to ecology system and human beings as endocrine disrupting
chemicals (EDCs). In this work the photodegradation mechanism and pathways of
sunscreen agent 2-phenylbenzimidazole-5-sulfonic acid (PBSA) were investigated under
artificial solar irradiation with the goal of assessing the potential of photolysis as a
transformation mechanism in aquatic environments. The quantum yield of PBSA direct …
