In an extensive environmental study, field samples, including soil, water, rice, vegetable, fish, human hair and urine, were collected at an abandoned tungsten mine in Shantou City, southern China. Results showed that arsenic (As) concentration in agricultural soils ranged from 3.5 to 935 mg kg(-1) with the mean value of 129 mg kg(-1). In addition, As concentration reached up to 325 microg L(-1) in the groundwater, and the maximum As concentration in local food were 1.09, 2.38 and 0.60 mg kg(-1) for brown rice, vegetable and fish samples, respectively, suggesting the local water resource and food have been severely contaminated with As. Health impact monitoring data revealed that As concentrations in hair and urine samples were up to 2.92 mg kg(-1) and 164 microg L(-1), respectively, indicating a potential health risk among the local residents. Effective measurements should be implemented to protect the local community from the As contamination in the environment.
在中国南方汕头市的一个废弃钨矿进行了一项广泛的环境研究，采集了土壤、水、水稻、蔬菜、鱼类、人发和尿液等现场样本。结果表明，农田土壤中砷的浓度范围为 3.5 至 935 毫克/千克，平均值为 129 毫克/千克。此外，地下水的砷浓度高达 325 微克/升，当地食物中最高的砷浓度分别为糙米、蔬菜和鱼类样本中的 1.09、2.38 和 0.60 毫克/千克，表明当地的水资源和食物已受到严重的砷污染。健康影响监测数据显示，头发和尿液样本中的砷浓度分别高达 2.92 毫克/千克和 164 微克/升，表明当地居民存在潜在的健康风险。应采取有效措施保护当地社区免受环境中砷污染的影响。
