[ES] Se estudia el contenido de siete elementos trazas potencialmente contaminantes en hojas de cuatro especies arbóreas ubicadas en la cercanía de una fundición de plomo en la localidad de Lastenia, y se la compara con los valores obtenidos para una zona testigo ubicada en la localidad de Yerba Buena, ambas en la Provincia de Tucumán. Jacaranda mimosifolia sería la especie que posee mayor cantidad relativa de Cr, Cu, Pb, Zn y Cd en sus hojas, no así para Co y Ni. La distancia a la fuente de contaminación es un factor que influye directamente en el contenido de tales elementos, en las hojas de las especies estudiadas. Los mayores contenidos de Cu, Pb, Zn y Cd se detectaron en la zona cercana a la fundición, esa correlación no es tan directa para Cr, Coy Ni.
[EN] The amount if seven potentially toxic trace elements, are studied in leaves of four tree species placed near a lead smelter at Lastenia Town . A comparison among their concentration values and those obtained for the same species at Verba Buena Town, is made. Jacaranda mimosifolia is the species which has the highest concentration of Cr, Cu, Pb, Zn and Cd and this fact is not observed for Co and Ni. The distance from the contamination focus could be the main factor that determinate the element concentration in leaves. The highest concentration if Cu, Pb, Zn and Cd, was detected close to the smelter, this correlation is no so direct for Cr, Co and Ni.
