Arsenic and fluoride in water in northwestern Buenos Aires: their association with natural landscape elements

Numerous publications analyze the origin of Arsenic and Fluoride, their behavior and distribution in groundwater indicating the importance in understanding the relation between their occurrence with other physical and chemical properties. Here, such properties associated with elements of the landsca...
