Why is it in the news?
- IIT-Madras has developed a technology named ‘AMRIT’ (Arsenic and Metal Removal by Indian Technology).
More about the Technology
- Utilizes nano-scale iron oxy-hydroxide.
- Selectively removes arsenic and metal ions when water passes through it.
- Aims to address the removal of arsenic and metal ions from water sources.
- Aligns with the Government of India’s goal under the Jal Jeevan Mission to provide a safe and adequate water supply.
Jal Jeevan Mission · Launched in 2019 under the Ministry of Jal Shakti. · Aims to create water supply infrastructure for rural households, ensuring every household has Functional Tap Connection (FHTC) by 2024. · Focus Areas: Recharge and reuse through grey water management; Water conservation initiatives; and Rainwater harvesting to ensure sustainable water supply.
Arsenic (As) · Naturally occurring trace element found in many minerals, usually in combination with sulphur and metals. · Highly toxic in its inorganic form. · Long-term exposure linked to cancer, skin lesions, cardiovascular diseases, and diabetes. · In-utero and early childhood exposure linked to negative impacts on cognitive development and increased deaths in young adults. · In Taiwan, arsenic exposure linked to “Blackfoot disease,” a severe vascular disease leading to gangrene. · World Health Organization’s provisional guideline value for arsenic in drinking water: 0.01 mg/l (10 μg/l). · India’s permissible limit in the absence of an alternative source: 0.05 mg/l (50 μg/l). · Arsenic in groundwater first reported in 1980 in West Bengal, India. · Maximum number of arsenic-affected habitations exists in the Ganga and Brahmaputra alluvial plains. |
