The listed correlations are significant on the 95% probability level. Correlations significant on the 90% probabiity level are shown in italics. Underlined are the elements which were undetectable in large number of samples. Elements included in the statistical associations A1 and A2 are highlighted respectively in brown and green. See text for further details.
