A study will research in depth the current situation of subterranean water in the areas of Argentina affected by the presence of arsenic, where millions of people live. The research will provide a data base to the provinces and will permit a better management of the resource. The excess of arsenic in the water causes health problems, limits its consumption and extraction volume.
Dr. Clara López Pasquali de Araya, researcher and teacher, works in a problem which affects people in the interior of the country: the presence of arsenic in fresh water. In this interview to InfoUniversidades the researcher states that in Argentina arsenic contamination is serious and tells us about the diverse forms in which she, together with an interdisciplinary team, carries out a plan to raise public awareness for the zone’s population.
In a preliminary experiment researchers took out more than the half of the dangerous chemical present in the liquid. They made it using nanotubes which retain different metal, among them, arsenic. They plan to use them in filters for perforations, as the arsenic is present in at least 15 provinces, most of all in areas where there isn’t fresh water, so it affects the most vulnerable populations.
Researchers are working in the development of a method to remove the arsenic present in natural aquifers and turn water in apt for human consumption. The technique is simple and cheap and it is based in the use of metallic iron. Only in the province of Buenos Aires the water in the 80% of the territory is contaminated with arsenic. Long term consumption of this contaminating agent can cause the disease Chronic Endemic Regional Hydroarsenicism and diverse oncological pathologies.
A group of engineers, through the application of technologies for social development patented solar equipment to purify the water aimed at rural populations’ houses from the north of Argentina. The isolation situation requires a device which doesn’t need materials or maintenance and which, in case of needing it, it is simple to use for any person.
