| Summary: | The development of physiological tolerance to the chemical stress caused by pollution of the aquatic environment with cadmium ions can be detected by different factional and biochemical parameters of the algal cells present in the phytoplankton of different river sectors. The investigation of such parameters that indicate early symptoms of heavy metal pollution revealed that the intensity of enzymatic H2O2- degradation is a suitable tool to appreciate the tolerancc developed by phytoplankters to cope with polluting agents which act as oxidative stress factors. Among the main photosynthetic pigments, only the amount of chlorophyll-b exhibits a regular correlation with the degree of water pollution caused by cadmium. The influence of this heavy metal on the net biomass production of the phytoplankton is also investigated, and the usefulness of prokaryotic decomposers in the estimation of water quality is discussed. |
