Abstract

The activity of the borate deposits industries constitutes a point source and diffuse pollution of air, soil and water. Therefore, the study and experimentation on possible ways to offset this impact is a priority. A relatively new technique to decontaminate soils is phytoremediation, which uses plants and associated microorganisms. The first step is to identify tolerant plant species, which is the focus of this work. An experiment was conducted in the laboratory to evaluate the germination, survival and growth of different species in different concentrations of boron. At the beginning and end of the experiment was determined concentration of boron in the substrate for each treatment and for substrates with and without vegetation. Significant differences due to treatment, the species and species-treatment interaction. M. sativa, N. glauca and J. mimosifolia were the species most tolerant to boron. The other species showed a decrease in all variables-response function of the concentration of the contaminant. All had low survival in the highest concentration. The decrease of boron was highest in the treatment of 30 ppm of boron with M. sativa and the lowest was recorded in the treatment of 20 ppm of boron with J. mimosifolia and 30 ppm of boron with  More>>

(author) [Spanish] La actividad de las industrias borateras constituye una fuente puntual y difusa de contaminacion del aire, suelo y aguas superficiales y profundas. Por lo tanto, el estudio y experimentacion acerca de las posibles formas de contrarrestar este impacto constituye una prioridad. Una tecnica relativamente nueva para descontaminar suelos es la fitorremediacion, que emplea plantas y microorganismos asociados. El primer paso es detectar las especies vegetales tolerantes, lo que constituye el objetivo de este trabajo. Se realizo un experimento en laboratorio para evaluar la germinacion, la supervivencia y el crecimiento de distintas especies en diferentes concentraciones de boro. Al comienzo y al final del experimento se determino la concentracion de boro en el sustrato para cada tratamiento y para sustratos con y sin vegetacion. Se encontraron diferencias significativas debidas al tratamiento, la especie y la interaccion especie-tratamiento. M. sativa, N. glauca y J. mimosifolia fueron las especies de mayor tolerancia al boro. Las otras especies presentaron una disminucion en todas las variables-respuesta en funcion de la concentracion del contaminante. Todas presentaron una baja supervivencia en la maxima concentracion. La disminucion de boro fue maxima en el tratamientos de 30 ppm de boro con M. sativa y la menor se registro en los tratamiento de 20 ppm de boro con J. mimosifolia y de 30 ppm de boro con T. stans y S. oleraceae. Se concluye que N. glauca, M. sativa y J. mimosifolia podrian considerarse como prometedoras en remediacion. (autor)}
