[Hazardous residues in Mexico. Evaluation of health risks]

In Mexico about 90% of the hazardous waste is not treated adequately. Thus, a sizable proportion of the waste is improperly disposed of and released into the environment, polluting rivers, deserts, etcetera. The present article describes the health effects of hazardous waste and the technological alternatives to tackle these problems. In order to assess the risks posed by hazardous waste sites, a new approach, adapted to the health conditions and scarce resources of the country, has to be developed. The health conditions include malnutrition and infectious diseases; the scarcity of resources refers to qualified environmental laboratories, human resources with expertise in environmental sciences, and funding for the evaluation of hazardous waste sites. Furthermore, a more direct participation of the Ministry of Health in issues related to hazardous waste is needed. These elements should be taken into account to create a National Program for the Study of Hazardous Waste in Mexico.
