illumination of dark-adapted algal cell suspensions indicate the action site of water-polluting
herbicides and heavy metals in the photosynthetic apparatus which performs the light
energy conversion and thus ensures the primary production in the aquatic ecosystems. The
influence of the herbicides diuron and methylviologen and of two heavy metals (cadmium
and nickel) on the ground fluorescence, on the maximal fluorescence yield, on the variable …
