The tace metal (Cu, Zn, Cd, Mn) and phytochelatin(an intracellular chelator for metal ions) cellular content were determined in phytoplankton samples originating from four lakes (Greifen, Sempach, Lucerne, and Orta). The lakes differ in their metal concentrations and in other conditions (pH, trophic...
