Fluoroquinolone (FQ) derivatives with environmental friendliness regarding photodegradation, bioconcentration, and genotoxicity were selected from our previous works so that their transformation pathways of biological metabolism, photodegradation, microbial degradation, and chlorination disinfection could be studied. The pathways of these molecules and their derivatives were simulated to investigate the genotoxicity of their transformation products. The results showed that the genotoxicity of the biological metabolites, photodegradation products, and microbial degradation products of the maternal FQ derivatives partially increased, whereas the disinfection by-products exhibited lower genotoxicity than their precursors. Some designed FQ molecular derivatives still had potential environmental risks in biological metabolism, photodegradation, and microbial degradation. This study demonstrated that it is necessary to take into account the potential environmental risks of the transformed products of the modified FQs molecules during biometabolism, photodegradation, microbial degradation, and chlorination processes when designing novel FQ molecules. In future studies, assessing the potential environmental risks during various artificial or natural processes can be applied to screen environmentally friendly novel FQ molecules to avoid and or reduce their threat to environmental and human health.

新设计的氟喹诺酮类化合物的环境转化路径推断及其潜在的环境风险。

从我们以前的工作中选择对光降解，生物浓缩和遗传毒性具有环境友好性的氟喹诺酮（FQ）衍生物，以便研究其生物代谢，光降解，微生物降解和加氯消毒的转化途径。模拟了这些分子及其衍生物的途径，以研究其转化产物的遗传毒性。结果表明，母体FQ衍生物的生物代谢产物，光降解产物和微生物降解产物的遗传毒性部分增加，而消毒副产物的遗传毒性低于其前体。一些设计好的FQ分子衍生物在生物代谢，光降解，和微生物降解。这项研究表明，在设计新型FQ分子时，有必要考虑到生物代谢，光降解，微生物降解和氯化过程中修饰的FQs分子转化产物的潜在环境风险。在未来的研究中，评估各种人工或自然过程中潜在的环境风险可用于筛选环保的新型FQ分子，以避免和/或减少它们对环境和人类健康的威胁。设计新型FQ分子时的氯化和氯化过程。在未来的研究中，评估各种人工或自然过程中潜在的环境风险可用于筛选环保的新型FQ分子，以避免和/或减少它们对环境和人类健康的威胁。设计新型FQ分子时的氯化和氯化过程。在未来的研究中，评估各种人工或自然过程中潜在的环境风险可用于筛选环保的新型FQ分子，以避免和/或减少它们对环境和人类健康的威胁。
