Core Viewpoint - The article highlights the limitations of simple water quality testing pens, which are often misinterpreted by consumers as reliable tools for assessing drinking water safety. These devices lack comprehensive and accurate evaluation capabilities, potentially misleading the public about water quality safety [1][2]. Group 1: Limitations of Water Quality Testing Pens - Water quality testing pens can only measure a few indicators such as total dissolved solids (TDS), pH, and residual chlorine, failing to cover the 97 indicators outlined in national drinking water safety standards, which include harmful substances like E. coli, lead, and mercury [1][2]. - The testing methods of these pens differ significantly from national standards, which utilize more rigorous techniques such as weight methods for TDS and colorimetric methods for pH and residual chlorine, ensuring more reliable results [2]. Group 2: Regulatory and Public Awareness Recommendations - Government departments are urged to enhance regulation and public education regarding water quality testing, including stricter oversight of misleading advertising for testing pens and collaboration with professional organizations to disseminate knowledge [2]. - Online platforms should take responsibility for content verification and improve content delivery mechanisms using big data algorithms, while the public is encouraged to enhance scientific literacy and seek professional testing services for accurate water quality assessments [3].
