Soil contamination by polycyclic aromatic hydrocarbons (PAHs) is a widespread concern due to the high potential for human exposure through inhalation, ingestion, and dermal contact. In this study, we compared the efficiency of three different methods for PAHs extraction from model samples, including ultrasonic (US), mechanical shaking and purification with commercial QuEChERS kit (Shq), and ultrasonic extraction coupled with QuEChERS (USq) by gas chromatography coupled to a triple quadrupole tandem mass-spectromet...
