The strategies of metal tolerance developed by several plants that enable them to survive in contaminated and polluted sites allow that some of them may accumulate significant concentration of a specific element. The work presented here is part of a larger on going study about the uraniferous geochemical province of Central Portugal, and it focus only in a preliminary description of results obtained with aquatic plants that show potential for phytoremediation. We have observed that
Apium nodiflorum, Callitriche stagnalis, Lemna minor
and
Fontinalis antipyretica
accumulate significant amounts of uranium, whereas
Oenanthe crocata
inhibit the uranium uptake.
