In marine and freshwater ecosystems, unicellular photosynthetic organisms are being considered as members of great importance for the early detection of potential hazards. Moreover, microalgae are in the base of the food chain and the exposure to potential pollutants such as heavy metal pollution is crucial for any ecosystem because they can transport the pollution to higher organisms in the food chain and can cause a major inhibition of photosynthesis. On these scores, biochemical and molecular biology biomarkers should be seriously take part in any environmental assessment program in order to give the best and most effective results. In this work, Chlamydomonas reinhardtii was chosen to be exposed in several sub – lethal levels of Cd2+, Ni2+ and Pb2+ pollution and the effects of the metal exposure on cell growth rates, on the levels of certain metabolites and on specific enzyme activities were determined.
