摘　　要：The rise of industrialization and urbanization has exacerbated environmental pollution, raising public concern about environmental quality. Real-time pollutant detection and rapid responses to environmental changes are crucial for safeguarding both the environment and human health. Traditional chemical analysis methods, though accurate and sensitive, are expensive, complex, and require specialized equipment and personnel. In contrast, smartphone-assisted electrochemical sensors could offer a novel, rapid, sensitive, and cost-effective solution for environmental monitoring. In this review, the working principle of electrochemical sensors was first introduced, including how their sensing elements and conversion systems work together to generate an electrical signal proportional to the concentration of the target substance. Next, the role of smartphones in this system was discussed. The challenges faced in designing smartphone assisted electrochemical sensor systems were also discussed in detail. In terms of applications, this article reviews the latest progress of smartphone assisted electrochemical sensors in detecting heavy metal ions, mycotoxins, bacteria, the veterinary drug and pesticide residues, and other compounds, and discusses their potential in environmental monitoring and public health. Despite hurdles in technology integration and data processing, smartphone-assisted electrochemical sensors are poised to become increasingly vital in environmental monitoring as technology progresses and is gradually becoming a powerful tool for cross industry monitoring and analysis.
