Study aim: "The main objective of the present study was to evaluate the influence of particle size on the desorption, bioavailability, and bioaccumulation potential of cypermethrin in benthic invertebrates, which were quantified by consecutive Tenax extraction, solid-phase microextraction (SPME), and bioaccumulation testing using Lumbriculus variegatus, respectively."
