Arsenic is ubiquitously found metalloid that commonly contaminates drinking water and agricultural food. To minimise the ecotoxicological effect of arsenic in the environment, it is important to ameliorate the deleterious effects on human and animal health. We investigated the effects of arsenic on cattle by estimating arsenic concentration in biological samples of cattle that consumed contaminated drinking water and feedstuffs directly or indirectly. We have selected arsenic prone village that is Ghentugachi, Nadia district, West Bengal, India, along with arsenic safe control village, Akna in Hoogli district, West Bengal, India. It is found that arsenic is deposited highly in blood, urine and faeces. Agricultural field is contaminated through cattle urine, hair, faeces, cow dung cakes and farmyard manure. Bioconcentration factor and biotransfer factor are two important biomarkers to assess the subclinical toxicity in cattle, as they do not exhibit clinical manifestation like human beings.
砷是一种广泛存在的类金属，通常会污染饮用水和农产品。为了将砷在环境中的生态毒理学影响降至最低，减轻其对人类和动物健康的有害影响至关重要。我们通过估计直接或间接饮用受污染饮用水和饲料的牛的生物样本中的砷浓度，来研究砷对牛的影响。我们选择了印度西孟加拉邦纳迪亚区的根图加奇这个砷易患村，以及印度西孟加拉邦胡格利区的阿克纳这个砷安全对照村。研究发现，砷在血液、尿液和粪便中高度沉积。农田会通过牛的尿液、毛发、粪便、牛粪饼和农家肥受到污染。生物浓缩因子和生物转移因子是评估牛亚临床毒性的两个重要生物标志物，因为它们不像人类那样表现出临床症状。
