化学计量学在水体微塑料识别中的应用
Chemometrics in the Identification of Microplastics in Aquatic Ecosystems
摘要
Abstract
Plastic pollution stands as a significant environmental challenge of our time,with vast amounts of plastic waste entering aquatic environments through various pathways and degrading into microplastics(MPs)measuring less than 5 mm.These MPs are widely distributed in water bodies,posing a potential threat to ecosystems and human health.Thus,it is imperative to develop effective analytical methods for the identification and detection of MPs.Current MP identification techniques,including visual,spectroscopic,and chemical imaging methods,offer distinct advantages but are generally time-consuming,costly,and subject to human bias,thereby hindering technological ad-vancement.The emerging chemometrics technology provides a powerful tool for processing and auto-mating the analysis of large datasets,revolutionizing MP identification.Research has shown that combining traditional MPs recognition methods with chemometric techniques can increase recognition accuracy from 60%to 98%,and achieve automated data analysis,greatly improving efficiency and accuracy.In addition,the development of in-situ detection technology can help to reduce sampling costs and realize frequent and long-term monitoring of MPs.This review summarizes the existing methods for identifying MPs in aquatic environments along with their limitations,introduces the work-flow of chemometrics,and discusses its current applications and latest developments in MP identifi-cation.It highlights the crucial role of chemometrics in data processing,technical optimization,and qualitative and quantitative analysis.Finally,the paper addresses some of the current limitations of chemometric technology and offers recommendations and perspectives for its further development and application.关键词
