GALEX Spectroscopic observations in the Far UV and in the Near UV are complemented by Mid-/Far-IR data from ISO to analyze a sample of galaxies in the ELAIS S1 field. We show that the FUV-NUV cannot be used as a proxy for the UV slope β beyond a redshift z = 0.10 - 0.15. In addition, we estimate the UV dust attenuation from the FIR/FUV dust ratio and we compare it to the UV slope β which was proposed as a dust attenuation estimator. For this sample of MIR-selected galaxies, we find a large dispersion and the dust attenuation estimated from β could be wrong by several magnitudes.
