Explanation:

Researchers in West Bengal have developed and commercialised a rice variety that is resistant to arsenic. The new rice variety, Muktoshri — also called IET 21845 — was developed jointly by the Rice Research Station at Chinsurah, coming under West Bengal’s Agriculture Department and the National Botanical Research Institute, Lucknow, over several years. A gazette notification for the commercial use of Muktoshri was issued by West Bengal last year. This variety absorbs very less amount of arsenic from soil and water than the other varieties of rice. West Bengal is among the States with the highest concentration of arsenic in groundwater, with 83 blocks across seven districts having higher arsenic levels than permissible limits. Several studies have shown that arsenic from groundwater and the soil can enter the food chain through paddy.Long-term exposure to arsenic, mainly through drinking water and food, can lead to poisoning. Skin lesions and skin cancer are the most characteristic effects.
