The results of spectral study of eight Delta Scuti pulsating variables are discussed and compared with the results of the Am-stars investigation. It has been found, that the abundance anomalies of several chemical elements in Delta Scuti pulsating and Am-stars are similar. The iron and others elements abundance in the Delta Scuti and Am-stars correlates with the effective temperature. The microturbulent velocity depends on the effective temperature within the luminosity range of the investigated stars (V - IV). For the investigated Delta Scuti pulsating variables no correlation is found between the abundance and rotational velocities.
