Fluoride Action Network


Kidney damage in distal and proximal tubular function and in glomerular filtration occurred in 40-60 yr olds residing in El Qued an endemic fluorosis area in southern Algeria compared to normals from Algiers. Functional renal disturbances were proportional to the degree of fluoride (F-) accumulation which increased in relation to the level of F- in drinking water, the F- level in nails and the radiological grade of fluorosis.
