Two decades ago it was realized (Schatzman, 1958) that metals should be rapidly removed from the atmospheres of white dwarfs by diffusion through the steep pressure gradients present. Yet metals are observed. Their presence thus prompts us to consider the diffusion process in greater detail and to seek mechanisms which might deposit metals in WD atmospheres.
