title: Criticism of Lednev's mechanism for the influence of weak magnetic fields on biological systems.
abstract: V. V. Lednev has proposed a mechanism that he suggests would allow very weak magnetic fields, at the cyclotron resonance frequency for Ca2+ ions in the earth's field, to induce biological effects. I show that for four independent reasons no such mechanism can operate.
