| description | Habitat fragmentation allows for vegetative species to be used as indicators of environmental
pollution by heavy metals. Considering the distribution of Prosopis laevigata
(mesquite) and Schinus molle (pepper tree) heavy metal concentrations were determined
as potential indicators of environmental impact assessment for agricultural and livestock,
rural settlement, commercial and service, urban settlement and mining land uses. A total
of 30 sampling points were established during summer, autumn, winter and spring, based
on the presence of the two species. Applying the technique of ICP-MS, concentrations of
Al, As, Co, Cu, Cd, Pb, Ti, V and Zn were determined. With a statistic model the interactions
between species, type of land use and season with respect to the concentration of these
minerals in the leaf material were determined. Results indicated that the presence of heavy
metals is determined by the effect of the species, land use and season, and the possible
association between these. The specie of mesquite was the most efficient for bioaccumulation
of Pb, Co and Al. In the same way, the pepper tree was more efficient with respect to
Ti. On one hand, trees located in the mining land use showed the highest concentrations
of Cu, Zn, Cd, Pb, Co and As. On the other hand, the spring season presented the highest
concentration of Cu, Zn, Co, Ti and V. With that, it could be demonstrated that As, Co, Cd,
Pb, Ti and Zn concentrations were above the normal limit. Therefore, the dynamics and
functionality, environmental factors and physiological differences to develop physicalchemical
processes in the absorption and transport of these elements towards the leaves
are a determining factor of vegetative species placed under conditions of fragmentation,
are good elements for surveying on pollution and environmental impact. |

La fragmentación del hábitat permite aprovechar especies vegetativas como indicadoras de contaminación ambiental por metales pesados. Considerando la distribución de Prosopis laevigata (mezquite) y Schinus molle (pirul) se determinaron las concentraciones de metales pesados en material foliar para evaluar el impacto ambiental de los usos de suelo agropecuario, residencial rural, comercial y servicio, residencial urbano y minero. Fueron establecidos 30 puntos de muestro durante las estaciones de verano, otoño, invierno y primavera, basados en la presencia de las dos especies. Aplicando la Técnica ICP-MS fueron determinadas las concentraciones de Al, As, Co, Cu, Cd, Pb, Ti, V y Zn. Con un ANOVA se probaron las interacciones entre especie, tipo de uso de suelo y estación con respecto a la concentración de estos minerales en material foliar. Los resultados indicaron que la presencia de metales pesados está condicionada por el efecto de la especie, uso de suelo y la estación, así como la posible asociación entre estos. El mezquite resultó ser más eficiente en la bioacumulación de Pb, Co y Al. En el caso del pirul solo fue más eficiente con respecto al Ti. Los árboles ubicados en el uso de suelo minero obtuvieron las mayores concentraciones de Cu, Zn, Cd, Pb, Co y As. Por otra parte, la estación de primavera incidió en la mayor concentración de Cu, Co, Ti y V. Con esto se pudo demostrar que As, Co, Cd, Pb Ti y Zn presentaron concentraciones arriba del límite normal en material foliar. Por lo tanto, la dinámica y funcionalidad, factores ambientales y diferencias fisiológicas para desarrollar procesos físico-químicos en la absorción y transporte de estos elementos hacia las hojas son un factor determinante de las especies vegetativas situadas bajo condición de fragmentación, lo que contribuye ser un buen elemento de estudio de la contaminación y evaluación del impacto ambiental.
