在一项广泛的环境研究中，在中国南方汕头市的一个废弃钨矿采集了野外样本，包括土壤、水、水稻、蔬菜、鱼、人发和尿液。结果显示，农业土壤中砷（As）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，地下水中砷的浓度高达325微克/升，当地食物中糙米、蔬菜和鱼样本的最大砷浓度分别为1.09、238和0.60毫克/千克，这表明当地水资源和食物已受到砷的严重污染。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，这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危害。（C）2009爱思唯尔有限公司。保留所有权利
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 mu g L-1 in the groundwater, and the maximum As concentration in local food were 1.09, 238 and 060 mg kg(-1) for brown rice, vegetable and fish samples, respectively, suggesting the local water resource and food have beets severely contaminated with As. Health impact monitoring data revealed that As concentrations in hair and urine samples were tip to 2.92 mg kg(-1) and 164 mu g 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.
