IN THE SPOTLIGHT
Removing Arsenic from Water through Nano filters
The use of nanomaterials from low-value agricultural by-products provide clean water for drinking and cooking. It has the potential to enhance the productivity of Filipino farmers and improve his and her quality of like in an affordable manner.
Arsenic is considered a major health risk by the World Health Organization which has set a maximum limit in drinking water to 10 parts per billion (0.01 milligrams per liter) of arsenic. At these very low levels, arsenic analysis is expensive and requires sophisticated equipment.
Arsenic contamination of groundwater and surface water is not well studied in the Philippines where arsenic is a pollutant from copper and nickel mining as well as from the semiconductor industry.
What is troubling is the less well known but equally important possibility that communities close to volcanoes are also exposed to arsenic contamination. This is due to the soil and groundwater characteristics as well as the volcanic activity nearby.
Arsenic contamination is highly associated with clay soils with suspended arsenic compounds as well as young volcanic deposits or hot springs and river deltas.
