dc.description.abstract	We study the nonrelativistic limit of the theory of a quantum Chern-Simons field minimally coupled to Dirac fermions. To get the nonrelativistic effective Lagrangian one has to incorporate vacuum polarization and anomalous magnetic moment effects. In addition to that, an unsuspected quartic fermionic interaction may also be induced. As a by-product, the method we use to calculate loop diagrams, separating low and high loop momenta contributions, allows us to identify how a quantum nonrelativistic theory nests in a relativistic one.
