We determined abundances of O, Ca, Fe, Ba and Y for a sample of dusty anddust-free A stars, taken from the list of Cheng et al. (1992). Five of thestars have an infrared-excess due to circumstellar dust. Ongoing accretion fromtheir circumstellar surroundings might have modified the abundances in thephotospheres of these stars, but our results clearly show, that there is nodifference in the photospheric composition of the dusty and dust-free stars.Instead all of them show the typical diffusion pattern which diminishes towardslarger rotational velocities.Comment: 8 pages, 3 figures, accepted for publication in A&

Do dusty A stars exhibit accretion signatures in their photospheres?
