Nuclear effects in the small [ital x] region of hadron-nucleus Drell-Yan processes at 800 GeV are analyzed. We employ the parton recombination model to describe the suppression in the [ital R][sub DY][sup [ital p][ital A]]([ital x][sub 2]) ratio and we compare it with [ital R][sub EMC]([ital x]), in the same kinematical region. Our results show that shadowing effects in Drell-Yan and deep inelastic scattering processes admit a description based on this model in both cases but with different characteristic parameters. Good agreement with experimental results is obtained.
