Extensive field sampling of natural marshes was conducted along the East and Gulf coasts of the United States, and along the shores of the Great Lakes. Spartina alterniflora was collected from the seawater marshes and Cyperus spp. collected from the freshwater marsh areas. In the saltwater marsh, Mn and Zn concentrations were slightly lower than those previously determined in greenhouse and disposal site studies with contaminated sediments, while the concentrations of the remainder of heavy metals were similar. Calculation of total uptake values indicated that only Cd may be of concern. Cadmium levels in Cyperus species in naturally occurring marshes were similar to those of a greenhouse flooded (reduced) environment. Iron and manganese were generally present in lower concentration in the natural marsh than in the greenhouse plants grown on contaminated sediment, while the remainder of the heavy metals examined were present in higher concentrations.-from US Govt Reports Announcements, 23, 1981
