Accumulation and partitioning of arsenic in rice varieties of Ambagarh Chowki, Rajnandgaon district, Chhattisgarh

Abstract

Six most popular and cultivated rice varieties (viz. MTU-1010, Swarna Masuri, MTU-1001, Mahamaya, one Hybrid and one local variety) of Ambagarh Chowki block, Rajnandgaon district, Chhattisgarh, were collected and analyzed for arsenic content in root, straw and grain. The Hybrid variety contained the higher mean value of arsenic content in root (1536 µg kg-1), straw (530 µg kg-1) and grain (189 µg kg-1). Further, local variety (desi) contained the minimum arsenic content in root (mean value of 1276.7 µg kg-1), straw (mean value of 365 µg kg-1) and grain (mean value of 76.7 µg kg-1). The mean arsenic content in rice grain was found in the order of Hybrid (189 µg kg-1) > Mahamaya (120 µg kg-1) > Swarna Masuri (119 µg kg-1) > MTU-1010 (118.8 µg kg-1) > MTU-1001 (103.3 µg kg-1) > local variety (76.7 µg kg-1).
