柬埔寨及越南高砷地下水利用风险评估图（2020）
收藏资源简介：
1) 柬埔寨湄公河沿岸及越南南部各行政区（District）对应的Population Attribute Function（PAF）和Excess death（ED）数值，其中PAF反映了各行政区利用高砷地下水的综合健康风险，ED为行政区每年因饮用高砷地下水而产生的额外死亡人数的估计。 2) 用于计算PAF和ED数值的水砷数据点来源为Resource Development International water quality database, UNICEF administered well database（柬埔寨）和 the Department of Water Resources Management（越南），人口数据来源于2019年两国的人口普查报告。本项目对PAF和ED计算结果具有自主知识产权。 3) 数据计算利用涵盖241个行政区共计95421个水砷数据点及最新的人口普查数据，为各行政区提供了充分的高砷饮用水风险评估参考。 4) 本研究以行政区为单位，对柬埔寨湄公河沿岸及越南南部地区的高砷地下水健康风险进行了综合计算与评估，并为将来两地的疾病防治与高砷地下水治理政策的制定提供了重要参考。
1) Population Attribute Function (PAF) and Excess Death (ED) values corresponding to each district along the Mekong River in Cambodia and the southern administrative districts of Vietnam. Specifically, PAF reflects the comprehensive health risk of utilizing high-arsenic groundwater in each district, while ED is the estimated annual excess number of deaths caused by drinking high-arsenic groundwater in the respective district. 2) The water arsenic data points used for calculating PAF and ED values are sourced from the Resource Development International water quality database, the UNICEF-administered well database (Cambodia), and the Department of Water Resources Management (Vietnam). Population data is derived from the 2019 national census reports of the two countries. This project holds independent intellectual property rights for the calculation results of PAF and ED. 3) The data calculation utilized a total of 95,421 water arsenic data points covering 241 districts, combined with the latest census data, providing sufficient reference for high-arsenic drinking water risk assessment in each district. 4) This study comprehensively calculated and assessed the health risks of high-arsenic groundwater in the areas along the Mekong River in Cambodia and southern Vietnam, taking districts as the statistical unit, and provided important references for future disease prevention and control as well as the formulation of high-arsenic groundwater governance policies in these two regions.
