Micro total analysis systems (μTAS) which have received great interest in the recent years and successfully employed for fluid processing in microchannels at microliter levels are powerful alternatives to traditional macroscale analytical systems. Unique benefits arise in the scaling down of traditional macroscale systems, including significant decrease of reagent, sample and energy consumption, faster and cost-effective analytical processes and lowered analysis time. Furthermore, μTAS can be efficiently automated which leads to higher throughput and multiplexing.

In this review paper, mainly green aspects of μTAS such as reducing of the volume of sample and solvents, using green solvents in μTAS, minimization of the generated waste and cost-effective processes for μTAS are discussed. The recent applications of green μTAS in the detection of various pollutants including heavy metals, pharmaceutical compounds, and dye compounds in environmental samples such as wastewaters, river waters are also demonstrated and highlighted.

微型总分析系统 (μTAS) 近年来受到极大关注，并成功用于微升级微通道中的流体处理，是传统宏观分析系统的强大替代品。传统宏观系统的按比例缩小带来了独特的好处，包括试剂、样品和能源消耗的显着减少、更快且具有成本效益的分析过程以及更短的分析时间。此外，μTAS 可以高效自动化，从而实现更高的吞吐量和多路复用。

在这篇综述论文中，主要讨论了 μTAS 的绿色方面，例如减少样品和溶剂的体积、在 μTAS 中使用绿色溶剂、最小化产生的废物和 μTAS 的成本效益流程。绿色 μTAS 最近在检测废水、河水等环境样品中的各种污染物（包括重金属、药物化合物和染料化合物）中的应用也得到了展示和强调。
