Fig. 7. Concentration maps of total brilliant sulfaflavine (BF) concentrations (mass of dissolved and adsorbed dye per unit volume of bulk soil) in core cross sections from the 0.5- to 0.6-m layer and from the 0.2- to 0.3-m layer. Heights of the cross sections from the bottom of the soil cores are indicated. The triangles on the concentration scale indicate the expected total tracer concentration when the initial soil solution is completely replaced by the applied solution and in equilibrium with the adsorbed dye concentration. Closed triangle is for the 0.2- to 0.3-m layer and open triangle for the 0.5- to 0.6-m layer.
