    We show that higher-order vacuum polarization would contribute a measurable net charge to atoms, if the charges of electrons and positrons do not balance precisely. We obtain the limit |Qe + Qē| < 10-18e for the sum of the charges of electron and positron. This also constitutes a new bound on certain violations of PCT invariance.
