To enlarge our database of Chemically Peculiar (CP) stars, we compiledpublished data concerning the He-weak and He-rich stars observed byhigh-resolution spectroscopy techniques during last decades. Twenty He-weak and28 He-rich stars have been added to the database. We have also distinguishedroAp stars from stars previously identified as Ap stars. To deepen ourknowledge on statistical overview of the abundance anomalies versus thephysical parameters of stars, we compared our data with previous compilations.We applied statistical tests on our data and found interesting correlations foreffective temperature and surface gravity for all type of stars and a fewcorrelations for projected rotation velocity only for He-rich stars. Because ofthe lack of the data we couldn't check whether being a member of binary systemis affecting on chemical peculiarities of those stars.
