Abstract: | Abstract The inhibition of growth by different concentration of eight heavy metals: Cd, Cr, Co, Cu, Hg, Ni, Se and Tl, in inorganic medium at pH 3 and 6.5, was studied in four green algae: Chlorella protothecoides Krüger, Chlorella saccharophila (Krüger) Migula, Coenochloris sp. and Stichococcus bacillaris Naegeli. The results suggest that pH has an important effect on heavy metal toxicity in algae although it is difficult to establish a relationship between pH and heavy metals. |
