“…Unlike previous reports [5], regarding the correlation of metals in leaves and sediments in Avicenia marina, the concentrations of Cu and Zn were 50 % lower in R. mangle leaves. Of particular interest, the regression model showed a positive relationship in the concentration of Cu and Zn in sediments and leaves (except for Zn in winter) (Figure 12A and 12B).…”

“…This plays an important role because tracer metals (TM) residues are among the most critical pollutants due to their persistence and toxicity. Mangrove trees have physiological capacities to adsorb metal ions through sediment biosorption and accumulation of metal ions in their tissues [5,6].…”

“…The capacity of mangrove species to translocate trace metals to their tissues is influenced by various parameters, including salinity, pH, Electrical conductivity (EC), Total Dissolved Solids (TDS), and chemical oxygen demand (BOD and COD), which affect the translocation of trace metals from the sediment to the tissues. Additionally, factors such as the type of sediments, life stage, age, morphology of the tree, and biomass also play a role in this process [5,22].…”

The objective of this work was to analyze the potential of Rhizophora mangle as a bioindicator of seven heavy metals, Fe, Cu, Zn, Mn, Ni, Cr, and Cd, in the mangrove sediments of the Navachiste lagoon complex (NAV). The concentration of trace metals (TM) in sediments and tis-sues (leaf, stembark, and root of R. mangle) were determined by digestion with nitric acid (HNO3), whereas the metal absorbance was measured by atomic absorption spectrophotometry with an air-acetylene flame. The enrichment factor, the bioavailable fraction, the seasonal varia-tion of heavy metal concentrations and their correlation with those determined in R. mangle tissues were assessed. Metal concentrations found in sediments were as following: Fe>Mn>Zn>Cr>Ni>Cu>Cd, and for tissues: Mn>Fe>Zn>Cu>Cr>Ni>Cd, and regarding the roots, the findings were as following: Fe>Mn>Zn>Cu>Cr>Ni>Cd. The highest trace metal concentra-tions were correlated with silt, clay, and organic matter in sediments with basic pH. The highest salinities were found adjacent to R. mangle trees. Of all the trace metals analyzed, there was only a positive linear regression between the bioavailability of Mn in the sediment with the concen-tration of Mn in leaf tissue consistently throughout the year. The Cu bioavailability in the sedi-ment showed similar positive linear regressions except for winter, where it did not show this pattern. These results suggest that the concentrations of Mn and Cu in the R. mangle leaf could be a potential bioindicator of environmental exposure to anthropogenic sources of contamination by these trace metals in sediments
