This study investigated the sorption capacity of estrogenic compounds—such as estrone (E1), 17β-estradiol (E2), and 17α-ethynylestradiol (EE2)—of different sediment particle fractions. Two-sized fractions of sediment were used in the experiments, with a particle size 1 μm up to 50 μm. Sorption kinetics were followed using a two-step reaction in which the major amount of chemicals was sorbed rapidly within minutes and then gradually increased until equilibrium was reached after 48 h. The sorption capacity of the fine particle fraction (particle size
