We show that wave operators for three dimensional Schrödinger operators H=-Δ+ V with threshold singularities are bounded in L1(\mathbb R3) if and only if zero energy resonances are absent from H and the existence of zero energy eigenfunctions does not destroy the L1-boundedness of wave operators for H with the regular threshold behavior. We also show in this case that they are bounded in Lp(\mathbb R3) for all 1≤ p ≤ ∞ if all zero energy eigenfunctions ϕ(x) have vanishing first three moments: ∫_\mathbb R3 xαV(x)ϕ(x)dx=0, |α|=0,1,2.
