“…105 Chen et al reported a mercury detector by utilizing the paper-based sensor combined with AuNPs to demonstrate a cheap/disposable sensing platform for resource-limited settings. 106 Wei et al, 107 Nguyen et al, 108 and Xiao et al 109 demonstrated portable smartphone-based heavy metal detectors to show the benefits of incorporating the mobile phones with customdesigned sensing platforms. However, colorimetric-based sensing techniques face challenges when used at the natural water bodies where numerous elements exist as interference factors, therefore fluorescent-based detection method is desirable for a field-deployable application.…”

Portable fluorescence sensors have been developed for biochemical detection, water quality monitoring, biomedical sensing, and many other applications. With help of advancement in modern electronics, conventional fluorescence-based instrumentations are now integrated into portable sensing devices for remote and resource-limited settings. In this work, fluorescence sensing technology is introduced and different applications of portable fluorescence sensors and their characteristics are reviewed. Current issues, technological challenges, and future direction of the portable fluorescence sensor development are discussed. The goal is to provide a comprehensive survey on the recent advancements in optics, semiconductors, smartphones, and many other manufacturing technologies that increased the portability, miniaturization, and sensitivity of portable fluorescence sensor devices.

“…Currently, a lot of drinking water pollution is caused by heavy metals. Heavy metals are mainly metals with density above 4.5 g/cm 3 , which have certain toxicity, including Fe, Mn, Cu, Cd, Hg, Ni and other 45 elements, among which Cu, Zn, Fe and other metal elements are essential trace elements, but most of the elements are not necessary for life activities. AS is a non-metal, but its toxicity and some properties are similar to those of heavy metals, so it is also classified as a heavy metal.…”

“…In recent years, groundwater, farmland and crops are increasingly contaminated by heavy metals globally, which directly or indirectly lead to the increase of heavy metal content in drinking water, thus posing a threat to human health. Therefore, it is necessary to monitor and assess the heavy metals in drinking water [3][4].…”

The quality of drinking water is closely related to the health condition of the population. In order to effectively assess the heavy metal environment of drinking water in Guizhou Province, this paper first analyzed the distribution characteristics of heavy metals in drinking water, and then used the environmental health risk assessment model recommended by the United States Environmental Protection Agency (US EPA) to investigate and analyze the toxic and hazardous substances in drinking water in Guizhou Province in 2019 to assess the health risks of heavy metals in drinking water. The survey results showed that the cancer-causing health risks of drinking water in Guizhou Province exceeded the EPA evaluation standards, while the non-cancer-causing health risks were much lower than the evaluation standards. Finally, for the heavy metal environment of drinking water in Guizhou province, this paper proposes corresponding response strategies from two perspectives of water quality monitoring and government supervision.
