Abstract
The absorption coefficients usually applied to biogeochemical prospection may provide information on the substrate soil in natural and contaminated ecosystems since the chemical composition of the plants tends to reflect the availability of the elements The biogeochemical coefficients could be a parameter to assess the bioaccumulation potential of a flora species interactions involving the soil–plant system and presence or absence of contaminants such as metals This study applies the biological absorption coefficient the temporal absorption coefficient and the acropetal coefficient as parameters to evaluate the differential absorption in the selected representative species The Syagrus romanzoffiana Chamisso Glassman chosen as a representative species in this study is a palm tree species commonly known in Brazil as “palmeira jerivá” jerivá palm tree The representative species is widely used in landscaping and vegetation restoration in urban areas It shows major regional dispersion and is endemic in South America The results indicate that jerivá palm tree could be a useful indicator of soil contamination in tropical areas
