BHU Scientists Develop Low-Cost Nanotech Sensor for Real-Time Heavy Metal Detection in Ganga Water
Researchers at Banaras Hindu University have engineered an indigenous electrochemical sensor capable of detecting toxic lead and arsenic traces in the river Ganga within seconds.
In a significant breakthrough for environmental science and public health, a research team at the Institute of Science, Banaras Hindu University (BHU), has successfully developed a portable, low-cost nanomaterial-based sensor for real-time detection of heavy metal ions in the Ganga water system. Led by Professor Arvind Kumar from the Department of Chemistry, the innovation aims to revolutionize water quality monitoring along the river's extensive stretch across Uttar Pradesh and Bihar.
Traditional laboratory testing methods often take days to deliver results, but the newly patented sensor provides accurate digital readouts of lead, cadmium, and arsenic contamination levels within 60 seconds. The sensor utilizes modified carbon nanotubes that react specifically with toxic ions, making it field-deployable for Jal Nigam officials, local municipalities, and environmental activists who monitor ghat cleanliness on a daily basis.
University Vice-Chancellor Prof. Sudhir Kumar Jain lauded the research team, emphasizing BHU's commitment to translating academic excellence into practical solutions for societal welfare. The technology is currently undergoing commercialization talks with domestic manufacturing startups, with pilot rollouts expected across major ghats including Assi, Dashashwamedh, and Raj Ghat by the upcoming winter season.
