ABSTRACT
Environmental pollution (water, sediment and fish) poses serious threats to the Chapala lake, Mexico. We seek to identify the concentrations of totalMercury (Hg) in children, pregnant women and in reproductive age from the communities around the lake. We will use blood samples and hair samples as biomarkers. Exposure will be assessed by dietary habits (quantity, frequency, species and type of fish consumed).Taking in consideration that some groups may be more susceptible to Mercury (Hg). In particular, the fetus, newborn babies and infants are at high risk because their nervous system is particularly delicate. Exposure to Hg during pregnancy can affect the neuronal connection and the mielinization of the nervous system, which may result in reduced number of cells neurons " in active" at the end of life. Very limited data exists in Mexico, protection measures are difficult to support without reliable information (e.g., possible damage from fish consumption). Therefore, this investigation seeks to generate hypothesis (cross sectional study) regarding the concentrations of Hg inside the organism soon after the fish consumption. We will evaluate the possible health risk e.g., children'sneurological damages, pregnant women and those in reproductive age.
