Researchers at IIT Bombay have introduced AroTrack, an affordable and compact device that detects harmful pollutants such as phenol, benzene, and xylenols in water. Priced below ₹5,000, this device aims to transform water quality monitoring, especially in rural and underserved regions.

About AroTrack

• It is an affordable, compact device developed by IIT Bombay to detect water pollutants like phenol, benzene, and xylenols, priced under ₹5,000.
• Function: It uses a biosensor (MopR) derived from bacteria to detect harmful pollutants, triggering a color change that is measured by a light-emitting diode (LED) system.
• Key Features:
  • Compact and portable, battery-operated, and suitable for harsh environments.
  • Low-cost production via 3D printing and open-source electronics.
• Performance
  • Detects pollutants at concentrations as low as 10 parts per billion (ppb).
  • Operates efficiently in water temperatures up to 50°C, providing results in 30 minutes.
• Significance: It offers a practical solution for water quality monitoring in rural areas, with potential for global use in combating water pollution.
