Abstract
We present results of the study in MHD approximation of mean helicity (or chirality) appearance and generation in various turbulent flows. It is shown that the mean helicity is practically always nonzero in almost any hydrodynamic or MHD (EMHD) flow, and different properties of turbulent media depend on the magnitude of the mean helicity. At the same time, it is shown that an electromagnetic field with violated mirror symmetry induces chiral properties of plasma, and the form of the Ohm's law is essentially changed and depends on chirality parameters of the electromagnetic field.
