From: A new approach to using Diffusive Gradient in Thin-films (DGT) labile concentration for Water Framework Directive chemical status assessment: adaptation of Environmental Quality Standard to DGT for cadmium, nickel and lead

Linear regression models between dissolved and DGT labile concentrations for the determination of (A)-EQSDGT: (a) cadmium, (b) nickel and (c) lead. The regression line (black line) and its corresponding prediction interval (± 95%; green lines and shaded green area) are shown. The shaded area corresponds to the range of validity of the model, defined on the horizontal axis, indicating that for a measured dissolved concentration value within the range of validity of the model, 95% of the DGT results will be between these 2 lines.
