Indian Institute of Science Education and Research (IISER) in collaboration with private company has developed a new device-Arsenic Sensor and Removal Media to detect and remove arsenic content from water and make it safe and usable by households.
WHO’s permissible limit of arsenic in groundwater is 0.1 mg per litre. In India, it was revised recently by Bureau of Indian Standards from 0.05 mg/l to 0.01 mg/l.
Arsenic is a natural component in the earth’s crust and is highly toxic in its inorganic form.
