English abstract This study assessed the relation between Cu, Fe, M n, and Zn in the soils of the mangroves of Antonina and Guaratuba , on the coastline of the State of Paraná, and in the leaf tissues of A. shaueriana , R. mangle , and L. racemosa through the analysis of correlation levels between these two compartments. Leaf samples were collected for ten individuals of each species in a 1000 m 2 area delimited in each mangrove. Soil samples from 0 - 10 cm depth were taken from under the crown projection area of the selected trees to be submitted to chemical analysis. In the so ils, metallic micronutrients presented the following order: Fe > Mn > Zn > Cu. In the leaves, concentrations were species dependent. In A. shaueriana and R. mangle , the profile was Mn > Fe > Zn > Cu, while in L. racemosa , the sequence was: Fe > Mn > Zn > C u. Correlation analyses revealed only four significant correlations for Mn, Zn, and Cu in the soil and plant compartments. These results suggested that significant correlations depended on abiotic factors, inhibition between the elements, and immobilizatio n and/or adsorptions of these metals by the soil
