  Using generalized Sehgal equations for magnetic moments of baryon octet and
taking into account $\Sigma^{0}-\Lambda$ mixing and two particle corrections to
independent quark contributions we obtain very good fit using experimental
values for errors of such moments. We present sum rules for quark magnetic
moments ratios and for integrated spin dendities ratios. Due to the SU(3)
structure of our equations the results for magnetic moments of quarks and their
densities depend on two additional parameters. Using information from deep
inelastic scattering and baryon $\beta$-decays we discuss the dependence of
antiquark polarizations on introduced parameters. For some plausible values of
these parameters we show that these polarizations are small if we neglect
angular momenta of quarks. Our very good fit to magnetic moments of baryon
octet can still be improved by using specific model for angular momentum of
quarks.
