Continent-wide problem and challenges for mitigation of the groundwater arsenic problem in Latin America

摘要：

In Argentina, Chile, Bolivia, Peru, and Mexico at least 4 million people depend on drinking water with high toxic arsenic concentra tions. In most cases, arsenic originates from geogenic sources. In Argentina (and until 1970 also in Chile) over 1％ of the countrys population is exposed to the problem, whereas in Bolivia, Ecuador, Costa Rica, Nicaragua, E1 Salvador, and Guatemala, arsenic in drinking water has been detected recently, but the extent oi the problem and the numbers of people affected are yet unknown.
