El objetivo de este estudio fue analizar la concentración total de arsénico (As) y de cinc (Zn) en plantas dominantes en sitios ubicados a diferentes distancias de la presa de jales. El estudio se realizó en el municipio de San Francisco del Oro, al sur del estado de Chihuahua. Se muestrearon dos plantas dominantes en 10 sitios a una equidistancia de 300 m a partir de las presas de jales en dirección a los vientos dominantes. Las plantas se separaron en raíces, hojas y tallos, para un total de 60 muestras. Se tomaron como referencia datos de un estudio previo de muestras de suelo de 0 a 20 cm en cada uno de los sitios. Las muestras se sometieron a un proceso de digestión y se analizaron mediante un espectrofotómetro de absorción atómica con generador de hidruros para As y ICP-OES para el Zn. Se realizaron análisis de varianza y prueba de medias (ANOM P&lt;0.05) donde las variables fueron: distancia a la fuente y partes de la planta. Los resultados muestran que a medida que las plantas están más alejadas de las presas de jales sus niveles de concentración de As y Zn disminuyen, al igual que en el suelo. Las hojas son las que concentran más estos elementos. El huizache (Acacia farnesiana), el táscate (Juniperus deppeana), la jarilla (Baccharis glutinosa), el mesquite (Prosopis julifora) y el zacate pata de gallo (Cynodon dactylon) son las especies que presentaron las concentraciones más altas. No se en contraron evidencias de daños físicos en las plantas. Se halló lo esperado, es decir, que existe una tendencia de las plantas estudiadas a concentrar más As y Zn al estar cerca de la presa de jales.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT Plants that grow near mine tailings can accumulate by different ways potentially toxic elements (PTE) that can represent environmental problems in the ecosystems. The objective of this study was to analyze the total concentration of Arsenic (As) and Zinc (Zn) in the dominant plants in study sites located at different distances from mine tailings. The study was carried out in San Francisco del Oro Municipality, south of the State of Chihuahua, México. Samples were taken from two dominant plants in 10 sites at an equidistance of 300 m beginning with mine tailings downward following the direction of the wind. The sampled plants were separated into roots, leaves and stems to make up a total of 60 samples. Soil samples were also obtained from 0 to 20 cm in dept in each site according to a study previously done. All samples went through a digestive process and were analyzed an atomic absorption spectrophotometer with hydride gen-erator for As and ICP-OES for Zn. A variance analysis was obtained as well as the means separation test (ANOM P&lt;0.05) in which the variables measured were distance to the source and plants parts. The results showed that the further away the plants grow from the mine tailings the less As and Zn tend to accumulate in the plant tissues, and the less contaminated is the soil. Leaves tend to accumulate more of these elements. Acacia farnesiana, Juniperus deppeana, Baccharis glutinosa, Prosopis juliflora and the grass species Cynodon dactylon were the plant species found with higher concentrations. No physical damages were found on the plants. It is concluded that there is a tendency for the studied plants to accumulate more As and Zn when growing closer to the mine tailings.]]></p></abstract>
