Chronic Arsenicosis of Cattle in West Bengal and It's Possible Mitigation by Sodium Thiosulfate.

Thirty milch cows having arsenic concentration in hair varying from 3 to 4 mg/kg from Dakhin Panchpota village of Nadia district, West Bengal, were divided into three equal groups where high amount of arsenic is reported to be present in soil and ground water. Groups II and III received, respectively, sodium thiosulfate 20 and 40 g to each animal for 30 days as a pilot study, whereas group I served as untreated control. Arsenic content of milk, feces, hair, and urine was estimated before and after administration of sodium thiosulfate orally at two dose level once daily for 1 month.
