Figure 2. Mean concentrations of DIC and 4-OH-DIC as a function of time in (A) sludge-amended soil and (B) compost-amended soil and curves of the applied kinetic models. BEM: Bi-exponential model; DIC: Diclofenac; FODED: first-order double-exponential decay; FOTC: first-order two-compartment; SFO: a single first-order; 4-OH-DIC: 4-hydroxy-diclofenac.
