A metallurgical industry in San Luis Potosí city, México, has contaminated the zone by lead (Pb) and arsenic (As). Since 1989 were reported by our group high concentrations of Pb in blood (PbB) and As in urine (AsU) in the local children. In present work, a Risk Communication Program (RCP) was generated to inform the children about the environmental risks of the site where they live, and to change conducts to diminish the exposure to Pb and As. We worked with 170 children (5 to 7 years) of the zone. The RCP was applied and the evaluation was realized by means of analysis of drawings, questionnaires and biological monitoring. In drawings of the children appeared toxic elements such as Pb, contaminated soil, cigarettes, among others. In the questionnaires applied to the children and family parents it was possible to estimate a change in the knowledge and in some conducts with regard to the pollutants, their effects and their exposure. There was not a decrease in the levels of PbB and in the levels of AsU. These were due probably because the principal route of exposure is not only the soil that had been contemplated previously.
