  In the present paper we study the Faddeev-Popov path integral quantization of
electrodynamics in an inhomogenious dielectric medium. We quantize all
polarizations of the photons and introduce the corresponding ghost fields.
Using the heat kernel technique, we express the heat kernel coefficients in
terms of the dielectricity $\epsilon (x)$ and calculate the ultra violet
divergent terms in the effective action. No cancellation between ghosts and
"non-physical" degrees of freedom of the photon is observed.
