The results of a search for line profile variability (LPV) and polarimetric (pLPV) in spectra O stars are reported. observations were made with the 1.8-m telescope Korean Bohyunsan Optical Astronomical Observatory (BOAO) 1-m 6-m telescopes Special Astrophysical (SAO), Russia. Regular LPV all program found. We analyze connection between presence magnetic field nitrogen abundance anomalies, influence weak fields on pLPV. statistical properties mean fluxes OB studied.
