베트남 우물에서 높은 양의 비소를 함유한 것으로 밝혀졌다
호주 네트워크 뉴스에 따르면 새로운 십 년 간의 연구를 통해 베트남의 밴 phuc의 작은 마을에서 대규모의 지하수의 과잉 양수를 통해 자연스럽게 높은 양의 비소가 깨끗한 대수층의 지하수로 흘러 들어가고 있다고 보도했다.
세계 보건기구 지침에 따르면 마시는 물에서 비소의 양은 리터당 10 마이크로그램인 반면 밴 phuc의 비소 농도는 10마이크로그램의 10-300배 이상인 것으로 밝혀졌다.

Study finds high arsenic levels in Vietnam wells
A new decade-long study that focused on the small village of Van Phuc in Vietnam has found that large-scale over-pumping of groundwater in the village is drawing naturally high levels of arsenic in groundwater into clean aquifers, according to an article on Australian Network News.
While the World Health Organization guidelines for arsenic in drinking water are 10 micrograms per liter, concentrations in Van Phuc are 10 to 300 times higher than that, the article reported.
"The phenomena we observe in Van Phuc village can be considered as a typical natural phenomena of arsenic contamination in the whole of the Red River Delta," said study co-author Pham Hung Viet of the Hanoi University of Science. "It can be considered one of the most densely populated areas in the world, with about 17 to 20 million people living in these area."
According to the article, arsenic poisoning over a long period of time causes skin, lung, bladder and kidney cancers and visible disfiguring skin lesions.
Pumping for municipal water supplies has doubled between 2000 and 2010 in the village, the article reported, and nearby Hanoi's population of six and a half million is growing by 400,000 each year, causing more and more pressure on the water supply.
