Abstract

NARANJO-SANCHEZ, Yury A.  and  TRONCOSO-OLIVO, Walberto. CONTENTS OF CADMIUM, COPPER, ZINC, AND LEAD IN ORGANS OF RHIZOPHORA MANGLE IN RIVER SEVILLA MOUTH-CIÉNAGA GRANDE DE SANTA MARTA, COLOMBIAN CARIBBEAN. Bol. Invest. Mar. Cost. [online]. 2008, vol.37, n.2, pp.107-129. ISSN 0122-9761.

In order to determine the contents of cadmium, copper, zinc, and lead in leaves, stalks, and root of Rhizophora mangle, samples from three parcels located in the river Sevilla mouth - Ciénaga Grande de Santa Marta, were taken in October 2003. Measures of metals concentrations were made through the Inductively Coupled Plasma Atomic Emission Spectrometry technique (ICP-AES). The results indicated that lead concentration in R. mangle organs was below method detection limit (<2.38 μg/g) except the absorbent root (16.3 μg/g); and significant differences exist in the contents of cadmium, copper, zinc, and lead into R. mangle organs, following this concentration order: absorbent roots > stalk > young leaves > adult leaves > aerial roots.
