摘要
喹诺酮类抗生素(Quinolones,QNs)被广泛应用于医疗卫生、种植业、水产养殖业和畜牧业等,因其具有较高的吸附系数(Kd)和有机碳分配系数(Koc),能在环境中长久存在并经迁移转化排放到土壤、水体中,进而对植物生长和代谢产生影响.本文详述了QNs对陆生植物、水生大型植物及浮游植物生长和代谢的生态毒理效应研究进展,重点综述了不同QNs胁迫下这些植物生长、细胞形态、光合作用、抗氧化系统、渗透调节、代谢指标的响应情况.最后对QNs植物生态毒性机制进行了展望.
Abstract
Quinolone antibiotics(QNs)are widely used in medical care,agriculture,plantation,aquaculture,animal husbandry and so on.Because of their high adsorption coefficient(Kd)and organic carbon partition coefficient(Koc),they can exist in the environment for a long time during which migration and transformation occurs.After being discharged into the soil and water bodies later,they can affect plant growth and metabolism.This study presented an overview of the advancements in research concerning the ecotoxicological impacts of QNs on the growth and metabolic processes of terrestrial plants,aquatic macrophytes,and phytoplankton.It specifically examined the responses of these organisms to various forms of QNs stress,encompassing aspects such as growth patterns,cellular morphology,photosynthetic activity,antioxidant mechanisms,osmotic regulation,and metabolic parameters.Finally,the prospect of the further research on plant ecotoxicity mechanism of QNs have been discussed.
