“Fluor is an element abundant in nature. In the right quantities, it is essential for the development of teeth and bones. However, under specific conditions, the concentration of fluoride (F) in ground and surface water can exceed safety levels and becomes toxic for human health. This may lead to skeletal and/or dental fluorosis, two chronic biogeochemical diseases that occur in various countries around the world.

According to UNESCO, more than 200 million people worldwide rely on drinking water with fluoride levels exceeding the present World Health Organization (WHO) norm of 1.5 mg/l. The Ethiopian Central Rift Valley (ECRV) is one of the most affected areas with an estimated 8 million people potentially at risk of fluorosis. Due to its geology and climate, it suffers from some of world’s highest concentrations of fluoride, mainly in deep wells in the semi-arid parts.

Dr Redda Tekle Haimanot and Seifu Kebede (Addis Ababa University) have studied the fluoride problem in the ECRV region for several years. In this webinar, they will discuss the magnitude of the problem, the risk factors and socio-economic consequences. The speakers will also discuss preventive measures that hold promise, and why they are relevant to other parts of the world suffering from high fluoride levels.
