New technology that could lead to far lower levels of fluoride in drinking water has been developed by Ethiopian and Spanish scientists.
Addis Ababa University (AAU) and the Spanish National Research Council (CSIC) announced that they have registered a new patent for a technology for defluoridation, using local materials.
The technology is based on the use of natural Zeolite, a volcanic rock, found throughout the Ethiopian countryside.
“We are very happy that Spain and Ethiopia were and are able to work together on a scientific project and discover this technology. The patent is registered in both countries and we should all be proud,” said the Spanish Ambassador to Ethiopia, Miguel Fernandez Palacios.
“It is a first for Addis Ababa University to register a patent as an institution, making this all the more exciting,” said Masresha Fetene, Professor at AAU.
Studies suggest around 14 million Ethiopians may be at risk of dental and skeletal fluorosis, conditions that weaken the teeth or bones of the sufferer.
“What will make this project sustainable is that we do not need to import any material from outside. We have everything we need here. Zeolites are very easy to extract as they are formed on the surface of the Earth,” said Isabel Diaz from CSIC.
Zeolites are used in production of detergents and soft drinks. Many companies currently import the materials, despite their abundance in Ethiopia.
The World Health Organisation (WHO) has established a limit for the concentration of fluoride in drinking water of 1.5 milligrams per litre, describing water with a higher concentration as harmful.
Children are particularly affected by excessive fluoride intake, as their permanent teeth are still developing.
In the Ethiopian Rift Valley area, more than 40 percent of drinking water sources have a fluoride concentration exceeding the WHO limit.
“It really is a huge problem that needs more attention. We believe this new project is more sustainable because of the use of zeolites. We hope that this discovery will contribute a lot to the efforts already being done to extract fluoride from drinking water,” said Professor Fetene.
