Inductively Coupled Plasma (ICP),Some recent results are reported concerning early O and OBN stars, He abundance in h and χ Persei, possible N deficiency in the open cluster NGC 6231, interstellar abundance inhomogeneities, possible, results obtained by different groups are compared. For the early O stars, the and radial gradients
