Trace metal contamination of the aquatic plant Hydrilla verticillata and associated sediment in a coastal Alabama creek (Gulf of Mexico - USA)

► Sediment and H. verticillata exhibit moderate metal concentrations in the study area. ► Metal concentrations in H. verticillata can be up to five times higher than in sediment. ► H. verticillata may uptake and store several metals (Cd, Hg, Ni, and Zn) from sediment.
