This method has been extended by Schat and ten Bookum (1992), who used EC10o, defined as the lowest effective concentration that inhibits root growth completely. These authors suggested that other parameters can also be obtained from the root elongation data no observable effect, NOEC, and EC50, equivalent to ED50.
