本PPT演示的目的是评估自然环境中的砷暴露 美国拥有的社区供水系统 以及减少暴露的解决方案。该方法包括: 估计美洲原住民的数量 通过公共数据审查接触砷； 尿砷浓度的测定 54个沃克河派尤特部落的样本 通过饮酒接触砷的成员 水和 审查技术替代方案和政策 减少砷暴露的建议。 CDC的另一项砷暴露研究是降低砷水平 饮用水:砷对人体负担的影响，目标是: 尿砷浓度的测定 沃克河派尤特部落社区；和 评估术后尿砷浓度的变化 建造除砷处理厂。第三个项目是减少内华达州舒尔茨砷暴露。结论: 社区砷暴露 水系统的污染严重 影响美洲土著部落；高砷暴露与健康 生物标志物测量存在于 美洲原住民暴露于 通过饮用水摄入砷；和 减少长期失业的解决方案 曝光需要合作 但是很及时。包括表格、数字。

The objective of this powerpoint presentation was to evaluate arsenic exposure from Native American-owned community water systems and solutions to reduce exposure. The approach included: estimating the number of Native Americans exposed to arsenic through public data review; measuring arsenic concentrations in urine samples of 54 Walker River Paiute tribal members exposed to arsenic via drinking water; and, reviewing technical alternatives and policy recommendations to reduce arsenic exposure. Another CDC Arsenic Exposure Study is presented, Reducing Arsenic Levels in Drinking Water: Effects on the Body Burden of Arsenic, with the goals of: determining the urinary arsenic concentrations in the Walker River Paiute Tribal community; and, evaluating variations in urinary arsenic concentrations after construction of an arsenic removal treatment plant. A third project is presented of reducing arsenic exposure in Schurz, Nevada. Conclusions: arsenic exposure via community water systems is disproportionately impacting Native American Tribes; high arsenic exposure and biomarker measurements exist for Native Americans exposed to arsenic via their drinking water; and, the solution to reduce long-term exposure needs to be collaborative but timely.
