Nuclear effects in the small 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 R f&„(x2} ratio and we compare it with Rz«(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. PACS number(s}: 25.40.Ve, 13.85.Qk, 24.85.+p, 25.30. — c
