Cortezas de Prosopis laevigata (Fabaceae) y Schinus molle (Anacardiaceae) como bioindicadoras de contaminación por metales pesados

Abstract

The tree bark is a valuable component to diagnose heavy metal air pollution. In bark of P. laevigata and S. molle presence of eleven heavy metals was evaluated, as indicator of environmental impact in San Luis Potosí, México. Based on the presence of both species on a soil system fragmented agricultural uses, rural settlements, trade and services, urban settlements and mineral uses, bark samples were taken during summer, autumn, winter and spring seasons. In each species thirty exemplars were sampled. Concentrations of Al, As, Co, Cu, Cd, Cr, Ni, Pb, Ti, V and Zn were determined by applying the ICP-MS technique, and for data analysis the General lineal model was applied. Results indicated that the average concentrations vary according to Ni> Al> Zn> Pb > Cu> As> Ti> V> Cd> Cr> Co. The presence of heavy metals was determined by the species effect, land use and season, and the relationship between these factors. The pepper tree bark was found to have higher concentrations of Al, As, Co, Cd, Cr, Ni, Pb and Ti. The highest concentrations of Al, Cu, Cr, Co and Ni were in the fall season. The urban settlement showed higher concentrations of Al, Co, Cr, Ni, Ti and V; meanwhile in the mining soil use Cu, Cd, Zn and Pb were relevant. The potential bio-indicator value of bark of both species was evidenced. Consequently, it is convenient to continue with these studies to increase knowledge of the environmental conditions of the San Luis Potosí.

La corteza arbórea constituye un elemento viable para diagnosticar la contaminaciónpor metales pesados. Fue evaluada la presencia de once metales pesados en cortezade P. laevigata "mezquite" y S. molle "pirul" como indicador de impacto ambiental enSan Luis Potosí, México. Basado en la presencia de estas dos especies sobre un sistemafragmentado por usos de suelo agropecuario, asentamiento rural, comercial y servicio,asentamiento urbano y minero, se tomó muestras de corteza durante las estacionesde verano, otoño, invierno y primavera. Se aplicó la técnica ICP-MS y se determinó lasconcentraciones de Al, As, Co, Cu, Cd, Cr, Ni, Pb, Ti, V y Zn, diseñando un modelo GeneralLineal para su análisis. Los resultados indicaron concentraciones promedio de Ni>Al>Zn>Pb>Cu>As>Ti>V>Cd>Cr>Co. La presencia de metales pesados fue condicionada por elefecto de la especie, uso de suelo y la temporada, así como la relación entre estos factores.Las cortezas de S. molle resultaron tener mayores concentraciones de Al, As, Co, Cd, Cr,Ni, Pb y Ti. En otoño se presentaron las mayores concentraciones de Al, Cu, Cr, Co y Ni.El uso de suelo para asentamiento urbano presentó las mayores concentraciones de Al,Co, Cr, Ni, Ti y V y el uso de suelo minero las de Cu, Cd, Zn y Pb. Se demuestra el potencialbioindicativo de la corteza de ambas especies. Se sugiere continuar realizando estudiosque permitan ampliar el conocimiento de las condiciones ambientales de la zona.
