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

Toxicol Int. 2011 Jul;18(2):137-9. doi: 10.4103/0971-6580.84266.


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. Paddy straw, mustard oil cake, and water fed by animals were also assayed. Sodium thiosulfate significantly decreased arsenic load in milk, urine, and hair after 1 month. In milk, arsenic concentration was decreased significantly which may be beneficial for animal and human beings.
