摘要
介绍了环境中残留的三嗪类除草剂对水生生物及人类产生的危害,阐述了藻类叶绿素荧光技术检测三嗪类除草剂的原理、发展历程及研究现状。综述了藻类叶绿素荧光技术在快速检测痕量三嗪类除草剂、分析其生物毒性上的研究进展,针对该技术检测灵敏度提升的研究也做出相关的分析;总结了藻类叶绿素荧光技术在实际应用过程中的优越性与不足之处,并提出藻叶绿素荧光技术的未来发展方向应是优化现有的检测技术条件、筛选出更灵敏的叶绿素荧光参数或是基于藻类荧光对除草剂的响应特性开发出检出限更低、灵敏度更高的新型藻类生物传感器,并能够应用于水环境的原位、在线及连续监测,以更好地实现水中三嗪类除草剂的常态化监测与风险评估。
The hazards of residual triazine herbicides in the environment to aquatic organisms and humans are introduced,and the principle,development history and current research status of triazine herbicide detection by algal chlorophyll fluorescence technology are described.The basic reviews the research progress made in the rapid detection of trace triazine herbicides and the analysis of their biotoxicity using algal chlorophyll fluorescence technology.Furthermore,it analyzes the ongoing efforts to improve the detection sensitivity of this technology.In conclusion,the advantages and limitations of algal chlorophyll fluorescence technology in practical applications are summarized,and the future development direction of this technology is proposed.To enhance its potential,the future focus should involve optimizing existing detection technology,identifying more sensitive chlorophyll fluorescence parameters,or developing new algal biosensors with lower detection limits and higher sensitivity based on the response characteristics of algal fluorescence to herbicides.Moreover,the aim should be to apply this technology for in situ,online,and continuous monitoring of the water environment,thereby enabling better regulation,monitoring,and risk assessment of triazine herbicides in water.
