ABSTRACT: To assess the exposure to lead in children living in various types of contaminated sites. The study was conducted from June 2008 to December 2009 at four sites in Mexico: Avalos metallurgical, Chihuahua; Morales metallurgical, San Luis Potosí (SLP); Trinidad pottery area, Tlaxcala and Cedral mine site, SLP. These sites contain different sources of lead. The metal levels were quantified in outdoor dust and in peripheral blood of children. Lead dust concentrations exceed the National Guidelines for residential soils (400 mg/kg) in a range of values for the four sites from 62 to 5 187 mg/kg. Regarding biological monitoring, the studied children showed maximum lead blood levels of 22 µg/dL in Cedral, 31 µg/dL in Morales, 32 µg/dL in Avalos, and 52 µg/dL in Trinidad. It is important to mention that in all the studied sites, a significative positive correlation was found between blood lead levels and the lead concentrations in dust. These sites are an example of the health risks related to lead exposure in Mexico; therefore, there is an urgent need for a national public health program aimed at reducing lead exposure in vulnerable populations.Salud publica de Mexico 08/2012; 54(4):383-92. · 0.94 Impact Factor -

ABSTRACT: We conducted a cross sectional study, involving 145 children randomly selected from three different socioeconomic locations. We selected social, environment and health indicators and measured the prevalence and prevalence odds ratios. Children from the brick producing site (segregation index 5), are exposed to high levels of multiple toxic agents, and showed the highest morbidity rates and malnutrition, anemia, dental fluorosis, and the lowest IQ, followed by children from municipal garbage dump (segregation index 4), where we detected the highest prevalence of dermatological and enteric diseases. Children from the Central Zone (segregation index 2) showed the lowest rates of malnutrition and higher IQ than the other two groups. A unified vision of social, health and environmental indicators opens the possibility of novel intervention programs and a legal framework that specifically protect children against environmental exposures.Journal of Community Health 03/2012; · 1.28 Impact Factor
