Linear regression models between DGT labile and dissolved concentrations for the determination of dissolved metal concentrations from DGT measurements: (a) cadmium, (b) nickel and (c) lead. The regression line and its corresponding prediction intervals (PI 95%; green dashed lines and light green area) are shown. WS wet season, DS dry season
