Research Progress on the Photochemical Transformation Effect of Antibiotics
The four types of antibiotics that are commonly detected in the environment are sulfonamides,macrolides,quinolones,and tetracy-clines.These antibiotics will further transform and disintegrate in the environment,among which photodegradation is a very important transfor-mation method.The photodegradation process of antibiotics is complex,divided into direct photodegradation,indirect photodegradation,and self-sensitized photodegradation.The mechanisms of different photodegradation methods are different,and factors such as pH,DOM,inorgan-ic ions,and light intensity in the environment will also affect the photodegradation process of antibiotics.The research progress on the photodeg-radation kinetics,influencing factors,and degradation mechanisms of antibiotics is discussed to provide a scientific basis for the ecological risk assessment of antibiotics and the formulation of environmental quality benchmarks.
