The previous works revealed the existence of the risks of exposure to pollutants through the consumption of the water in the localities of Ahomey and Houédo in Sô-Ava. It was thus advisable to look for biomarkers, indicators of exposure to these toxics. In this context, a survey was conducted at first to identify the characteristic disorders connected to exposure to xenobiotics. body-fluidsThis survey was completed by biochemical and hematological analyses of blood and urine of the investigated. The results revealed that: the characteristic clinical signs to lead and/or cadmium poisoning existed within the population; in particular, stomach pain, , symptoms connected to the reproduction, sign of bone pain, mental retardation, , asthenia, arterial high blood pressure, sight impairment, excessive perspiration, neurological and renal signs. Also in exposure areas, correlation between blood lead and lead in drinking water was high but that correlation was weak for cadmium. Besides, 80 % of the investigated.
