Comparison of the predicted surface abundances for stars of 1.8, 2.0, and 2.15 M_⊙ with different turbulence prescriptions and different initial metallicities with those derived (depicted as diamonds with their respective uncertainties) for the Am star HD 30210 (T_eff = 8082 K and log g = 3.92). The grey symbol for Sc indicates that it is not considered in the evolutionary models.
