Conclusion
The uptake of mercury bySynedra was investigated under several conditions. It was found that the uptake was much higher under illumination than in the dark. This increase was suggested the presence of an active uptake linked to the energy metabolism, which required light and Mg++. It was also shown that the uptake observed in a dark or by dead cells was due to passive adsorption.
