Abstract
The determination of As in groundwater is fundamental to assess its impact on public health. Here, we measured As concentration of groundwaters in 722 sites covering all 6 major provincial areas of Korea. Groundwater was measured As concentration in two occasions (summer and winter) employing highly sensitive ICP-MS. Among targeted 722 sites, seasonal variation of As concentration in groundwater was minimal, while geographical difference, prominent. The concentrations of As in groundwaters ranged from 0.1 to 48.4 μg/L and the majority displayed lower than 10 μg/L. However, some area exceeded 10.0 μg/L (2–3%) and most remarkably, the urinary excretion of As in the population around 3 groundwaters with high arsenic levels was measured to be markedly higher with all stratified analysis yielding higher As levels compared to non-contaminated area (< 5 μg/L). Especially, urinary As excretion of non-smokers was significantly higher in the contaminated area, suggesting the possible contribution of As-contaminated groundwaters to low-dose arsenic exposure.
