Arsenic Contamination in Some Selected Soils of Bangladesh

M. M. Hossain, M. A. Sattar, M. A. Hashem and M. R. Islam


The arsenic status of some selected soils was determined in ten thanas of four arsenic affected districts of Bangladesh. Thirty soil samples taking three from each of 10 thanas representing 4 districts viz. Gopalganj, Faridpur, Rajbari and Madaripur of Bangladesh were collected. The soils were collected from 3 depths viz. 0-15, 15-30 and 30-45 cm from each location. The arsenic content in soils of Gopalganj, Faridpur, Rajbari and Madaripur districts ranged from 3.96-25.09, 0-38.67, 1.32-36.99 and 1.32-38.19 ppm, respectively. Out of 30 samples, arsenic content was noticed for 21 samples at 0-15 cm depth (1.98-46.09 ppm), 26 samples at 15-30 cm depth (1.98-51.73 ppm) and 27 samples at 30-45 cm depth (1.98-54.05 ppm). Nine samples at 0-15 cm, 4 samples at 15-30 cm and 3 samples at 30-45 cm were free from arsenic contamination. On the other hand, 7 samples at 0-15 cm depth, 6 samples at 15-30 cm depth and 4 samples at 30-45 cm depth were found to be slightly arsenic contaminated. Correlation study of arsenic contents of soils was done with some soil properties viz. sand, silt and clay contents, soil pH, EC and organic matter status. Results showed that arsenic content correlated significantly with different soil properties.
