angroves are dynamic environments under constant influence of anthropic contaminants. The correlationbetween environmental contamination levels andpossible changes in the morphology of plants, evaluated bymultivariate statistics helps to highlight matching betweenthese variables. This study aimed to evaluate the uptakeand translocation of metals and metalloids in roots andleaves as well as the changes induced in both anatomy andhistochemistry of roots of Laguncularia racemosa inhabitingtwo estuaries of Espı´rito Santo (Brazil) with differentpollution degrees. The analysis of 14 elements in interstitialwater, sediments and plants followed by multivariatestatistics, allowed the differentiation of studied sites,showing good match between levels of elements in the environment with the corresponding in plants. L. racemosashowed variations in their root anatomy in different collectionareas, with highest values of cortex/vascular cylinderratio, periderm thickness and air gap area in Vit
