Physics and chemist characters and content in six heavy metals(Zn, Ni, Cu, Cd, Pb, Mn) have been studied in 37 soils of the "D.O.Ca.Rioja" using multivariate analysis techniques have been relationated heavy metals with soil variables. Pb,Mn and Zn values are relationated and negativaly correlationated with soil CaCO3. Medium values of heavy metals, never are over values of the 86/278/EEC european directive.
