Conclusions - Recent accurate abundance analyses of B-type stars in the OriOB1 association have shown that the dispersion of O and Si abundances between stars in the various subgroups found in previous analyses is a spurious result and the consequence of a bad characterization of the abundance errors propagated from the uncertainties in the stellar parameter determination. - The present day abundances of B-type stars in Ori OB1 are compatible at similar precision with other B-type stars in the Solar neighbourhood (Nieva & Przybilla 2012) and also with the last revision of abundances in the Sun (Asplund et al. 2009)
