Fig. 2. Scatterplot of predicted vs. observed copper, lead, mercury, and cadmium sediment concentrations. Predictions were made from averaged models. The lines represents perfect agreement between predicted and observed values (y = 1x + 0). Values above the line indicate sampling points with potentially enriched concentrations.
