New Delhi, July 4 -- A team of Indian scientists has developed an innovative, cost-effective sensor capable of detecting sulfur dioxide (SO2) gas at extremely low concentrations.



SO2, a harmful air pollutant released from vehicles and industrial emissions, is linked to respiratory problems, asthma attacks, and long-term lung damage.



Even brief exposure to SO2 can pose significant health risks, yet detecting the gas before it reaches harmful levels remains a challenge. Real-time monitoring of SO2 levels is critical for safeguarding public health and protecting the environment. However, existing detection technologies are often prohibitively expensive, energy-intensive, or incapable of identifying the gas at trace concentrations.
