Abstract
En la parte central del estado de Chihuahua (México) se encuentra la cuenca de drenaje que alimenta las lagunas endorreicas de Bustillos, y de los Mexicanos. Estos humedales de especial interés ambiental, se encuentran amenazados por una fuerte presión de actividades humanas. Para este trabajo se han planteado una serie de análisis químicos, físicos y microbiológicos, que determinan unos elevados índices de contaminación en estos hábitats acuáticos. Los resultados han mostrado bajos índices de oxígeno disuelto y elevadas concentraciones en nitratos y bacterias coliformes en el agua. Se ha detectado que las principales fuentes de contaminación de estos recursos hídricos son las actividades agropecuarias, los vertidos de aguas residuales de las áreas urbanas y, en mayor medida, por los desechos de los tratamientos industriales.
The lagoons de Bustillos, and de los Mexicanos are located in the center of the state of Chihuahua (Mexico). These wetlands of special environmental interest are endangered by severe pressure from human activities. These wetlands of environmental relevance are endangered by severe pressure from human activities. This study has raised a series of chemical, physical and microbiological analyzes, which determine high rates of contamination in these aquatic habitats. The results showed in water low levels of dissolved oxygen and high concentrations of nitrate and coliform bacteria. Has been detected the main sources of pollution of these water resources are caused by agricultural activities, wastewater discharges from urban areas and industrial waste.
