We deduce constraints on time-reversal-noninvariant (TRNI), parity-conserving (PC) hadronic interactions from nucleon, nuclear, and atomic electric dipole moment (EDM) limits. Such interactions generate EDM's through weak radiative corrections. We consider long-range mechanisms, i.e., those mediated by meson exchanges in contrast with short-range two-loop mechanisms. We find that the ratio of typical TRNI, PC nuclear matrix elements to those of the strong interaction are [approx lt]10[sup [minus]5], a limit about 2 orders of magntiude more stringent than those from direct detailed balance studies of such interactions. This corresponds to a bound of [vert bar][ital [bar g]][sub [rho]][vert bar][approx lt]10[sup [minus]3], where [ital [bar g]][sub [rho]] is a TRNI PC [rho][ital NN] coupling.
