Residues of Priority Organic Micropollutants in Eruca vesicaria (Rocket) Irrigated by Reclaimed Wastewater: Optimization of a QuEChERS SPME-GCMS Protocol and Risk Assessment

The increasing use of reclaimed wastewater in agriculture raises growing concerns about the accumulation of priority organic micropollutants in edible crops. In this study, we developed and validated a novel QuEChERS–SPME–GC/MS method for the simultane- ous determination of 15 polycyclic aromatic hydrocarbons (PAHs), 3 nitro-PAHs, and 14 polychlorinated biphenyls congeners in Eruca vesicaria (rocket) leaves. The method was optimized to address the matrix complexity of leafy vegetables and...
