Two aquatic macrophytes as bioindicators for medium-high copper concentrations in freshwaters

Plant scions of Ceratophyllum demersum L. and Potamogeton natans L. were exposed in controlled conditions to different concentrations of copper during approximately 2 weeks; Fv/Fm was monitored at regular intervals and relative growth rate (RGR) was calculated at the end of the trial. P. natans was...

Summary:Plant scions of Ceratophyllum demersum L. and Potamogeton natans L. were exposed in controlled conditions to different concentrations of copper during approximately 2 weeks; Fv/Fm was monitored at regular intervals and relative growth rate (RGR) was calculated at the end of the trial. P. natans was affected by Cu concentrations starting from 2 μM; C. demersum started to show significant reductions in growth and photosynthetic efficiency from 4 μM Cu. As it results from the observed data, the two aquatic macrophytes can be used as valid bioindicators for medium-high copper concentrations in freshwaters.
