Arsenic (As) is a class 1 nonthreshold human carcinogen that is ubiquitous in the natural environment. Aquatic submerged macrophytes have attracted considerable attention recently for their phytoremediation potential of As contaminated waters. The water purifying function of the macrophytes is most likely attributed to the role of the composite system (the plant—epiphytic bacteria system), which remains largely unknown.
