title: Monitoring heavy metal pollution by aquatic plants: a systematic study of copper uptake.
abstract: BACKGROUND
  The copper bioaccumulation by the floating Lemna minor and by the completely submerged Ranunculus tricophyllus as a function of exposure time and copper concentration was studied, with the aim of proposing these species as environmental biosensors of the water pollution.
  
  
  RESULTS
  The results show that both these aquatic angiosperms are good indicators of copper pollution because the copper uptake is the only function of metal concentration (water pollution).
  
  
  CONCLUSIONS
  Uptake behavior is reported as a function of the time and concentration, based on the results of a 3-year study. Kinetic evaluations are proposed.
