IISER Developed New Device To Detect And Remove Arsenic From Water- Details, purpose, Benefits, About
Indian Institute of Science Education and Research (IISER) in collaboration with the private firm 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.
The device is very easy to use, very cost effective and anyone can use it to detect arsenic easily. It uses very simply household detection sensing methodology. It is capable of sensing soluble arsenic (3) which cannot be easily detected and removed.
The device can show an immediate change in color in the arsenic contaminated water. It provides a holistic approach to immediate detection of arsenic contamination levels from available water resources and thereafter produces arsenic-free potable water.
The device has high sensitivity as it can sense up to parts per billion (ppb) level compared to many currently available techniques which sense parts per million (ppm).
About Arsenic Contamination
Arsenic is a natural component in the earth’s crust. It is widely distributed throughout the environment in the air, water and land.
Arsenic is highly toxic in its inorganic form; intake of soluble inorganic arsenic over a long period can lead to chronic arsenic poisoning (arsenicosis), diabetes, cardiovascular diseases and cancer.
WHO permissible limit of arsenic in groundwater is 0.1 mg per litre which was revised recently in India by Bureau of Indian Standards from 0.05 mg/l to 0.01 mg/l.
In India, Arsenic pollution big problem in Bengal and neighboring states. In Bengal, there are 83 blocks in eight districts where groundwater is arsenic contaminated. Malda, Murshidabad and Nadia districts have higher levels of arsenic concentration.
