The possible reasons of the solar iron abundance anomaly found by Simmons and Blackwell for the 2.2 eV lines are analysed. It is found that with the depth-dependent turbulent velocity this anomaly can be reduced but not eliminated. The iron abundance in the atmosphere of Arcturus is also analysed but no anomaly is found.
