摘要:The unicellular algaePseudokirchneriella subcapitata(Korschikov) Hindák has been frequently used forecotoxicological tests.In this paper, a calibration curve is proposed correlating absorbance values (684 nm) and cell density for routine ecotoxicological experiments. Density (cells/mL) could be estimated as follow: Cell Density = e{[ln (absorbance_684) +16.439]/1.0219}(n=130; r2=0.9998). Residual distribution revealed that the equation could be applied for algal densities under 5,000,000 cells/mL and/or absorbance values as high as 0.5.
