In this paper {ital CP}-violating nucleon-nucleon interactions are studied in several models. The experimental upper bounds on the atomic electric dipole moment (EDM) are used to constrain the {ital CP}-violating parameters of the underlying weak Lagrangian. We compare the constraints from this consideration with those obtained from the upper bound on the neutron EDM. We find that although the constraints from the former consideration are not yet as sensitive as the latter, in some models the constraints from both considerations are within an order of magnitude.
