An inescapable fact: Toxicity increase during photo-driven degradation of emerging contaminants in water environments

摘要: The occurrence of an enormous group emerging contaminants (ECs) is continuous concern for the safety and health human beings, as well ecosystem. Photo-driven technologies especially photochemical photocatalysis are considered to be promising effective removal various ECs from water. Although great advances in photo-driven performance have been achieved recently, toxicity problem remains important challenge yet. In this short review, we provided a general overview latest researches on evolution during degradation (including direct indirect photochemistry, photocatalysis) ECs. Particularly, increased was emphasized, possible reasons were also analyzed organic viewpoint essential characteristics mechanisms. light these mechanisms, discussed perspectives being performed by toxicologists environmental chemists completely eliminate application treatment their products future research.
