          Abstract

          Se estudió un jal de mina en Pachuca Hidalgo, con la caracterización física y química de residuos mineros, el contenido de elementos potencialmente tóxicos (cadmio, cobre, manganeso, níquel, plomo y zinc) y parámetros de vegetación. Se definieron nueve sitios de muestreo en el jal, en muestras compuestas se determinaron las características físicas, químicas y el contenido de elementos potencialmente tóxicos. Se utilizó el método de cuadrados para identificar especies vegetales y en muestras de tejido vegetal de cada especie se determinó el contenido de elementos potencialmente tóxicos. Los residuos mineros presentaron textura franco-arenosa, pH medianamente alcalino y bajo contenido de materia orgánica. El Zn (45 mg·kg-') y el Pb (14 mg·kg-1) fueron los elementos con mayor concentración. Se identificaron 25 especies de plantas, Haplopappus venetus fue la más dominante. Solanum corymbosum presentó mayor acumulación de Cu (6 mg·kg-1), Brickelia veronicifolia de Pb (5 mg·kg-1) y Zn (20 mg·kg-1), Atriplex suberecta de Cd (1 mg·kg-1), Cynodon dactylon de Mn (69 mg·kg-1) y Bouteloua curtipendula de Ni (4 mg·kg-1). Se sugiere el uso de éstas especies en la rehabilitación de jales mineros.

          Translated abstract

          The present study took place on a mine jal from Pachuca, Hidalgo. Such jal had the physical and chemical characterization of mining waste, the contents of potentially toxic elements (cadmium, copper, manganese, nickel, plumb, and zinc) and the vegetation parameters. Nine sampling sites were defined in the jal. The physical and chemical characteristics and the content of potentially toxic elements were determined in compound samples. The method of squares was used in order to identify plant species and in plant tissue samples of each species, the content of potentially toxic elements was determined. The mining wastes showed a franc-sandy texture and with a pH moderately alkaline and a low content of organic matter. The Zn (45 mg·kg-1) and the Pb (14 mg·kg-1) were the elements with a higher concentration. Twenty-five species of plants were identified and from these, Haplopappus venetus was the dominant species. Solanum corymbosum showed the highest accumulation of Cu (6 mg·kg-1) Brickelia veronicifolia of Pb (5 mg·kg-1) and Zn (20 mg·kg-1), Atriplex suberecta of Cd (1 mg·kg-1), Cynodon dactylon of Mn (69 mg·kg-1) and Bouteloua curtipendula of Ni (4 mg·kg-1). It is recommended to use these species in the rehabilitation of mining jales.
