Abstract

The extraction method of pharmaceutical and personal care products (PPCPs) has become a popular issue due to the emergence of PPCPs as contaminants. In this work, polycyclic musks, a typical type of PPCPs, were selected to test various techniques including microwave-assisted extraction (MAE), simultaneous distillation-solvent extraction (SDSE), Soxhlet extraction (SE), and ultrasound probe (UP). MAE and UP proved to be more effective pretreatment techniques than SE and SDSE, with high recovery, repeatability, accuracy, efficiency, little solvent consumption, and acceptable matrix effects. Notably, the chemical methods usually did not work well for the determination of bioavailability and the environmental fate of pollutants was overestimated. In this work, wheat (Triticum aestivum L.) was used as the ecological receptor to evaluate the bioavailability of chemical pollutants. The concentrations of polycyclic musks in sediments by way of UP extraction had a significant correlation (R 2 > 0.9, P
