Contamination by heavy metals is currently one of the most environmental concerns especially due to the toxicity, pervasiveness, and persistence of these substances. As they are not biodegradable, heavy metals are harmful not only for water, air, and soil but also for human health, even in very low traces. There is therefore a pressing need to develop an efficient, economic, and rapid analysis method to be applied in a wide range of conditions and able to detect very low contaminants concentrations. Currently, the most novel solution in this field is represented by the combination of electrospun nanofibers and highly sensitive electrochemical techniques. It has been proved that nanofibers, due to their outstanding properties, perfectly fit as sensing material when trace concentrations of heavy metals were investigated by anodic stripping voltammetry, envisaged as the most sensitive electrochemical technique for this kind of measurements. This work aims to provide an overview of the latest trends in the detection of contaminants by the simultaneous use of electrospun fibers and anodic stripping voltammetry. Indeed, a clear and comprehensive vision of the current status of this research may drive future improvements and new challenges.
重金属污染是当前最为严重的环境问题之一，尤其是考虑到这些物质的毒性、广泛性和持久性。由于重金属不可生物降解，它们不仅对水、空气和土壤有害，即使含量极低，也会对人类健康造成危害。因此，迫切需要开发一种高效、经济且快速的分析方法，该方法能够在广泛的条件下应用，并能够检测到极低浓度的污染物。目前，该领域最新颖的解决方案是将电纺纳米纤维与高灵敏度电化学技术相结合。事实证明，纳米纤维因其卓越的性能，在通过阳极溶出伏安法研究痕量重金属浓度时，作为传感材料非常合适，阳极溶出伏安法被视为这类测量中最灵敏的电化学技术。这项工作旨在概述通过同时使用电纺纤维和阳极溶出伏安法检测污染物的最新趋势。的确，对该研究现状有清晰而全面的认识可能会推动未来的改进和新的挑战。
