Abstract

Toxicities of Al, Cd, Co, Cr, Cu, Fe, Ni, Pb and Zn were tested using growth miniaturized algal bioassay with Chlorella kessleri, Raphidocelis subcapitata (=Selenastrum capricornutum), Scenedesmus quadricauda and Scenedesmus subspicatus. Toxicity hierarchy for all organisms, according to their mean values is: Cd > Co > Cr > Cu > Pb > Ni > Zn > Al > Fe. The sensitivity hierarchy is: Raphidocelis > Scenedesmus subspicata > Chlorella > Scenedesmus quadricauda. The most toxic element was Cd, which was the first in toxicity hierarchy for all tested organisms. Cd has a gradual toxic curve, and has showed no stimulation, similar to Pb. Scenedesmus quadricauda showed a peak shape of growth curve with stationary phase about 300 h. Another algae showed prolonged and approximately stabile stationary phase in the period of 300-700 h, under PhAR 180 ľE.m-2 . s-1, (40 W.m-2) 30 oC, and CO2 supply ca 2% (v/v).
