Freshwater plants present a different picture. Here, arsenite and/or arsenate are found as significant or major arsenicals, and arsenosugars are only occasionally detected (30). Methylarsonate and dimethylarsinate are also present in most samples at low levels. Interestingly, tetramethylarsonium ion was also reported in several freshwater plant species, generally as a trace constituent (30). 

Research on aquatic macrophytes as producers of biomass has been undertaken at Woods Hole Oceanographic Institution (WHOI) on the east coast and on the west coast by a group of collaborators in a joint effort known as the Marine Biomass Project. Studies at WHOI have focused on estuarine and coastal situations with some attention recently to freshwater plants. The Marine Farm Project has primarily been concerned with oceanic biomass production.
