Table 2: Values of EC50 parameter for microalga cultures exposed to Se salts, expressed as Se(+IV) and/or Se(+VI) concentrations (mg·L−1/μmol·L−1) in culture medium, as determined and published in the literature. In some studies Se concentrations (in mg·L−1) were expressed based on weight of elemental Se, while in present study it was expressed based on weight of sodium selenate (Na2SeO4). Table adapted from Vítová et al. (2011) [28].
