The Indian Institute of Technology (IIT) – Madras has developed a technology called ‘AMRIT’ (Arsenic and Metal Removal by Indian Technology) for the removal of Arsenic and Metal ions from water.
- The technology uses nano-scale iron oxy-hydroxide, which selectively removes arsenic when water is passed through it.
- This water purifier has been developed for both domestic as well as community levels.
About Arsenic
- Arsenic is a naturally occurring, semimetallic element widely distributed in the Earth’s crust.
- Arsenic levels in the environment can vary by locality, and it is found in water, air, and soil.
- Organic arsenic compounds contain carbon. Inorganic arsenic compounds do not contain carbon. Research indicates that inorganic arsenic is more toxic and its associated health effects are more severe.
- All arsenic is toxic to humans and can affect people of any age or health status.
- The most common source of arsenic in people is contaminated drinking water.
- Contamination from mining and fracking, coal-fired power plants, arsenic-treated lumber, and arsenic-containing pesticides also contributes to increased levels of arsenic in certain locations.
- Arsenic may be found in foods, including rice and some fish, due to its presence in soil or water.
- Arsenic may be a component of air pollution.
