In the present study, Arsenic (As) concentrations in underground water, soil, and plants (rice) and their inter-relationships in central and sub-mountainous Punjab, India were studied. Approximately, 32% of the tubewell water samples had As concentrations greater than the maximum permissible limit (10 μg As L(-1)) set by the World Health Organization (WHO) whereas in hand pump waters, As concentrations were within the safe range (i.e. <10 μg As L(-1)). As concentrations in tubewell waters were significantly correlated with As concentrations in surface soil (r = 0.57; P < 0.05) and plant samples (r = 0.27-0.82; P < 0.05) in central and sub-mountainous Punjab. The estimated daily intake of As through human consumption in rural and urban population was 0.016 and 0.012 μg day(-1) kg(-1) body weight respectively.
在本研究中，研究了印度旁遮普中部和山区地下水中的砷 (As) 浓度，以及土壤和植物（水稻）中的砷浓度及其相互关系。大约 32% 的管井水样中砷浓度超过世界卫生组织（WHO）设定的最大允许限值（10 μg As L(-1))，而在手压泵水中，砷浓度在安全范围内（即 <10 μg As L(-1))。管井水中的砷浓度与中部和山区的表层土壤（r = 0.57；P < 0.05）和植物样本（r = 0.27-0.82；P < 0.05）中的砷浓度显著相关。农村和城市人口通过人类消费摄入的砷的估计每日摄入量分别为 0.016 和 0.012 μg day(-1) kg(-1) 体重。
