Groundwater should not be used for farming purposes to prevent arsenic (As)exposure for farm products, especially in the case of rice, a team of researchers has said citing the case of West Bengal where arsenic has been found in high content in groundwater. Large-scale arsenic (As) poisoning, mainly through food chain contamination, is deemed to be a lethal problem in the rice-growing areas of the Bengal Delta Plain (BDP) and other parts of the world.<\/p>\n
The study paper by scholars and researchers from the School of Environmental Studies, the National Institute of Biological Genomics and Australias University Of Newcastle pointed out that since groundwater is more prone to arsenic exposure, farm products produced by using that water also become prone to the same exposure.<\/p>\n
To prevent this, the report has suggested stressing on rainy season farming so that rainwater can be used. This remedy is extremely important considering that West Bengal is among those states which have extremely high arsenic concentration in groundwater. Historically as many as 83 blocks scattered over seven districts in West Bengal have arsenic levels in groundwater higher than the permissible limits.<\/p>\n
The report, published in science magazine Environmental Science & Pollution Research, suggests if rice is cooked using arsenic-free water equivalent to three times of the quantity of rice being cooked, the level of arsenic exposure in that cooked rice comes down substantially.<\/p>\n","protected":false},"excerpt":{"rendered":"
