| 内容記述 | Concentrations of arsenic and other metals were examined in groundwater collcted in the middle and southern parts of Myanmar in 2015 and 2016. As the reference, tap water, river water, and bottle water samples were also analyzed. Arsenic concentration in water samples ranged from <0.01 to 209 ㎍/ℓ. About 28% of water samples collected in our sampling exceeded World Health Organization （WHO） drinking water guideline value （10 ㎍/ℓ） for arsenic. Interestingly, some tap water samples also had over the guideline value, suggesting that those public waters are not suitable for drinking. Geographical distribution of arsenic in groundwater revealed that hot spots of arsenic contamination were widely dispersed, not concentrated in a certain area. On the other hand, relatively high concentrations of arsenic were dtected in groundwater from 15 - 60 m depth, indicating that there is significant arsenic rich aquifer in this layer. For other metals, concentrations of managanese and uranium in some groundwater contaminated by arsenic were also higher than the WHO guideline values. therefore, human health risks by multiple elements including arsenic, manganese, and uranium through the drinking of groundwater are of great concern in Myanmar. | |||||
