Abstract

Our previous works had shown that drinking water in SO-Ava was contaminated with nitrates and their by-products. These nitrates by-products are extremely toxic for human being because of their capacity to transform hemoglobin in methemoglobin under the effect of Nitrosomonas and Nitrobacter bacteria especially with infants. It is in this context that the present study was conducted in order to examine the toxicity of these compounds on the inhabitants of Ahomey and Houdo to S-Ava, localities the most exposed to these xenobiotics through the drinking water. After urine and blood analyses on empty stomach, the results showed the presence of nitrites in urines in the case of 80 % of investigated followed by leucocyturia and by proteinuria. These symptoms added to the results of the blood parameters are proofs of an exposure with nitrates and an infection of enterobacteriological origin. The populations of these localities are thus exposed to the methemoglobin.
