We briefly present our approximate approach to the problem of polarized line formation in multi-level atoms taking into account the effects of partial frequency redistribution (PFR) and crossredistribution (XRD).We also present the influence of XRD on linear polarization profiles, taking the examples of Ca ii H and K and IR triplet lines, and the 3 P-3 S triplets of Mg i formed in an isothermal one-dimensional atmosphere.We show that XRD produces significant effects on the linear polarization profiles when the damping widths of the line components of the multiplet are comparable, like in the case of Mg i b triplet.
