  We address the issue of evaluating chiral effects (such as the newly
discovered chiral separation) in hydrodynamic approximation. The main tool we
use is effective theory which defines interaction in terms of chemical
potentials $\mu,\mu_5$. In the lowest order in $\mu,\mu_5$ we reproduce recent
results based on thermodynamic considerations. In higher orders the results
depend on details of infrared cutoff. Another point of our interest is an
alternative way of the anomaly matching through introduction of effective
scalar fields arising in the hydrodynamic approximation.
