Description
Light meson ($\pi,\sigma, a_0$) properties in the environment with chiral im-
balance will be analyzed with the help of meson effective lagrangian
associated with QCD. New spatial parity violating decays of scalar
meson arise as a result of mixing of $\pi$ and $a_0$ mesons. The pion electro-
magnetic formfactor obtains an unusual parity-odd contribution. Pion
effective masses vanish in flight. The possible determination of chiral
chemical potential in heavy ion collisions based on above mentioned
phenomena will be outlined.
