The results of spectral study of eight Delta Scuti pulsating variables.

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.
