Table 9. Element correlations. Correlations of mean log10 concentrations for stomach contents and sediment and stomach contents and liver matched by site and year. For all correlations, p < 0.05 and significant at alpha = 0.003 (shown in bold).

* Spurious correlation is a significant correlation that is unduly influenced by a few points. Number of correlations made for each species and compartment pair (liver, stomach, or sediment) was 15 (e.g., stomach contents and sediment for 15 elements in English sole), hence the significance level (alpha) for pearson correlation was 0.05 ÷ 15 = 0.003. Abbreviations for elements are in Table 3 and fish species are in Table 2.
