We investigate the incidence of nuclear effects in the extraction of unpolarized parton densities by means of a global LO QCD fit including data produced using deuterium targets. The data considered include DIS, Drell-Yan and W-production asymmetry. We evaluate the consecuences of nuclear corrections, through different models, in the analysis of the flavour symmetry breaking in the nucleon. The Gottfried sum rule is re-analysed.
