The effect of soil properties irrigated with effluent water of Lalmatiya was investigated for three consecutive year from Jan. 2013 to Dec.2015. The concentration of Arsenic in effluents water samples of range from 0.202 to 0.535 ppm in summer season, 0.195 to 0.522 ppm in rainy season and. 0.202 to 0.570 ppm in winter season 2013, 0.195 to 0.501 ppm in summer season 0.185 to 0.498 ppm in rainy season and 0.181 – 0.500 ppm in winter season 2014 and 0.185 – 0.495 ppm in summer season, 0.180 to 0.485 ppm in rainy season and 0.180 – 0.485 ppm in winter season in 2015. Arsenic concentration in soil sample of Lalmatiy coal mine area range varied from
0.506 – 0.692 mg/100g in 2013, 0.501 – 0.710 mg/100g in 2014 and 0.501-0.695 mg/100g in 2015 respectively. Analysis data indicated that the appropriate management of arsenic effected soil and Arsenic contaminated effluent water might increase the Arsenic availability in soil. Which in turn, might aggravate the Arsenic contamination of crops grown.
Arsenic is a general protoplasmic poison and it affects all systems in the body. Arsine can cross placental membrane and is known to be teratogenic to animal. Arsenicals are known to be carcinogenic to lungs in humans. They may also lead to skin cancer through the initial skin lesions.
Arsenic is highly hazardous to human and animal health. Higher concentration of arsenic in soil sample depends upon soil texture.
