AbstractThere have been substantial heavy metal toxicity studies encompassing microalgal species, while many of these studies were done with very low initial cell density and the parameters are not applicable for recent biomonitoring practice (e.g. using bbe Algae Toximeter). This study evaluated the acute toxic effects of Zn, Cd and Hg on growth of three green microalgal species, Chlorella pyrenoidosa, Scenedesmus obliquus and Chlamydomonas reinhardtii, with relatively high initial densities of 5.37x10(6), 1.87x10(6) and 1.31x10(6) cells/mL respectively by using SE media without EDTA. The half maximal effective concentrations (EC50) for the three algae after 24-96h exposure to different concentrations of heavy metal ions were determined. Mercury was much more toxic to the three algal species than Zn and Cd, and the EC50 values ranged from 0.16 to 4.83 mg Hg/L. The higher EC50 values in the present study than in some previous ones might be due to higher initial cell densities in our cultures. Scenedesmus obliquus was the most sensitive species to heavy metals, and thus has the potential to be used in biomonitoring practice, while Chlorella pyrenoidosa was the most tolerant.; There have been substantial heavy metal toxicity studies encompassing microalgal species, while many of these studies were done with very low initial cell density and the parameters are not applicable for recent biomonitoring practice (e.g. using bbe Algae Toximeter).
