Arsenic contamination of ground water in West Bengal, India, is a great concern for both human and livestock populations. Our study investigated and correlated the arsenic concentration in the drinking water, urinary excretion and deposition of total arsenic in hair of cattle at an arsenic contaminated zone in West Bengal. The results of our study indicated that the average concentration of arsenic in tube well water in contaminated villages ranged from 0.042 to 0.251 ppm and a statistical significant (p < 0.01) difference was seen when compared to samples from a non-contaminated zone. The arsenic concentration in urine and hair of cattle ranged between 0.245-0.691 ppm and 0.461-0.984 ppm, respectively. A close relationship was found between the total arsenic in drinking water urinary excretion (r² = 0.03664, p < 0.05) and the arsenic concentration in hair (r² = 0.03668, p < 0.05). Our findings indicate that quantification of arsenic concentration in cattle urine and hair can serve as biomarkers for both present and past exposure in cattle population.
印度西孟加拉邦地下水的砷污染，是人类和牲畜群体都极为关注的问题。我们的研究调查了西孟加拉邦一个砷污染区牛的饮用水中砷浓度、尿排泄量以及毛发中总砷的沉积情况，并进行了相关性分析。我们的研究结果表明，受污染村庄管井水中砷的平均浓度在0.042至0.251 ppm之间，与未受污染地区的样本相比，存在统计学显著差异（p < 0.01）。牛尿液和毛发中的砷浓度分别在0.245 - 0.691 ppm和0.461 - 0.984 ppm之间。饮用水中的总砷与尿排泄量之间（r² = 0.03664，p < 0.05）以及毛发中的砷浓度之间（r² = 0.03668，p < 0.05）都发现了密切关系。我们的研究结果表明，对牛尿液和毛发中砷浓度的量化可作为牛群当前和过去接触砷的生物标志物。
