Contaminants in Tissue of <strong>Fish</strong> and Crabs Collected in the <strong>Gladstone</strong> Areathe changing patterns of responses over space and time are a real effect, so the data are reported onthis two-way basis (locations by trips).Disease status – Two of the 13 metals showed a significant (P < 0.05) difference between normaland abnormal crabs, as listed in Table 2.1. It is notable that the abnormal crabs generally had higherlevels than the normal crabs.Table 2.1. Effects of disease status on the metal concentrations (dry-weight basis). Significant (P
