Heavy metals are naturally occurring elements. Their multiple industrial, agricultural, medical and technological applications have led to their wide distribution in the environment, including water bodies, raising concerns over their potential effects on human health. Klearia has developed PANDa, the first plug-and-play portable analyser for the detection of heavy metals in water. We have successfully developed a prototype for accurate arsenic detection (< 1ppb), fully automated, easy to use and with results available within two hours. Now, we aim at upgrading our prototype to detect the most common and harmful metalloids as well as organic pollutants and water indicators (pH, conductivity) in a single robust, quick, safe and cost-effective solution.
