Influence of selenium on toxicity of some heavy metals in the green alga Scenedesmus obliquus.
The green alga Scenedesmus obliquus was incubated with various heavy metals (Cd2+, Zn2+, Mn2+, Ni2+) in presence/absence of selenium. S. obliquus exhibited higher rates of growth and some metabolic activities in cultures containing 0.1 mM Se than those containing only the heavy metals. The positive effect of Se was found in presence of Cd2+ while that in the case of presence of Ni2+ was less pronounced.
