  In this paper we present a new catalogue of Chemically Peculiar (CP) stars
obtained by compiling publications in which abundances of metals are provided.
Our catalogue includes 428 stars for which the data were obtained through
spectroscopic observations. Most of them (416) are AmFm, HgMn and ApBp stars.
We have used this compilation to proceed to a statistical overview of the
abundance anomalies versus the physical parameters of the stars. The Spearman's
rank correlation test has been applied, and a significant number of
correlations of abundance peculiarities with respect to effective temperature,
surface gravity and rotation velocity have been found. Four interesting cases
are discussed in details: the Mn peculiarities in HgMn stars, the Ca
correlation with respect to effective temperature in AmFm stars, the case of
helium and iron in ApBp stars. Furthermore, we checked for ApBp stars using
Anderson-Darling test wether the belonging to a multiple system is a
determinant parameter or not for abundance peculiarities.
