Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water.
Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water. The technology could enable household testing for arsenic, empowering individuals to monitor their own water quality.
Arsenic contamination is a serious environmental and public health challenge affecting millions of people around the world. This contamination occurs when natural geological processes release arsenic from rocks and soil into groundwater and can be exacerbated by mining, industrial waste disposal and use of arsenic-based pesticides.
“Consuming arsenic-contaminated water can lead to severe health conditions including arsenic poisoning and cancers of the skin, lung, kidney and bladder,” said lead researcher Sunil Khijwania from the Indian Institute of Technology Guwahati. “By creating a sensor that is sensitive, selective, reusable and cost-effective, we aim to address the need for a reliable and user-friendly tool for routine monitoring, helping to protect communities from the risks of arsenic exposure.”
