In this study, a new method for acute biotoxicity assessment was proposed by measuring the glucose consumption of microbes with a personal glucose meter (PGM). To obtain an ideal biotoxicity assessment performance, an appropriate microbe was selected first, and then the relevant parameters, such as temperature and microbial concentration were optimized. Under the optimized parameters, the acute biotoxicity of four environmental pollutants (As3+, Ni2+, 4-chlorophenol, and 2,4-dichlorophenol), three wastewater samples and three soil samples were evaluated. This technology breakthrough will help us develop a low cost, easy to use water-environmental early-warning kit.
