The National Geographic Society together with Bayer AG is funding a research project for the "Removal of toxic arsenic species from drinking water by bacteria". The project team is headed by the young scientist and Emmy-Noether scholarship holder Andreas Kappler from the Center for Applied Geosciences at the University of Tübingen, Germany.
More than 10 Million People worlwide consume water having an arsenic contamination higher than the maximum tolerable value for human consumption. Intake of the highly toxic arsenic over long period of time leds to skin lesions and cancer with fatal cases.
The team around Andreas Kappler
works on a innovative technology, using the activity of bactery to clean the water from arsenic. The bacteria are involved in the formation of particular iron minerals that act as sorbents for arsenic. Clear target is to establish a robust method for providing clean water for the suffering people in arsenic contaminated areas in China and Bangladesh. Using both laboratory experiments in Tübingen and field studies in these areas the team will study in close cooperation with local scientists the efficiency of this approach.
The National Geographic Society
is funding the project under the framework of the "Global Exploration Fund" meant to support research for the exploration of new water sources and the intelligent use of the limited resources. Related information personal web site of Andreas Kappler Related studies
