Fig. 6. Simulated breakthrough curves calculated for three sets of linear sorption rate parameters at two pore water velocities. Solid lines represent curves at a pore water velocity of 36.47 cm h^-1, while the dotted lines represent curves at 0.00073 cm h^-1. The second set of parameters is identical to that given for dimethylphthalate (DMP) sorption to Oakville B soil in Table 1. The first and last set of parameters were obtained by varying f, while keeping the product fk_D constant
