Abstract: A micro level investigation was conducted in the Arsenic affected 10 villages of Ambagarh chowki block, Rajnandgaon district, Chhattisgarh, India, to determine the depth wise distribution of arsenic in soil. After analysing 120 samples of different soil depth and 40 plant samples from different villages, it is revealed that during pre-monsoon season, in 0-20 cm soil depth, arsenic content varied from 3.36 to 6.15 mg kg-1 with an average of 5.30±0.867 mg kg-1. In 20-40 cm soil depth, it varied from 3.12 to 5.89 mg kg-1 with an average of 4.84±0.965 mg kg1. At 40-60 cm soil depth, arsenic content varied from 1.65 to 5.12 mg kg-1 with an average of 3.36±1.227 mg kg-1. In post-monsoon season, in 0-20 cm soil depth, arsenic content varied from 3.01 to 5.95 mg kg-1 with an average of 4.86±0.896 mg kg-1. In 20-40 cm soil depth, it varied from 2.91 to 5.49 mg kg-1 with an average of 4.40±0.933 mg kg-1. At 40-60 cm soil depth, arsenic content varied from 1.01 to 5.12 mg kg-1 with an average of 3.36±1.227 mg kg-1. In the soils of studied area, arsenic content was below 10 mg kg-1, which is lower than the global average of soil arsenic 10 mg kg-1 and also less than the soils permissible limit for arsenic 20 mg kg-1 by environmental guideline. It was found that in surface soil, the concentration of arsenic was high as compared to sub-surface soil. Seasonal variation in arsenic content was also found and the concentration of arsenic in soil during pre-monsoon season is higher than in postmonsoon season.
