Fabric phase sorptive extraction (FPSE) has gradually become more widespread as a novel sorptive extraction technique since it has a number of advantages including a wide range of available materials, cheap and easy performance and highly efficient extraction. Because of this, FPSE has been applied in different fields to extract various types of analytes from different kinds of samples. In particular, it has been widely used in environmental applications.This review covers the use of FPSE in environmental samples. It discusses the optimization of the variables involved during FPSE and presents novel FPSE approaches applied to environmental samples. It also reviews figures of merit obtained using the FPSE methods developed and summarizes data on the occurrence of contaminants in different types of environmental samples. This is done by looking at a selection of different studies in which FPSE is applied to analyze environmental samples.

In this work, a simple, quick and efficient analytical method for determination of human and veterinary fluoroquinolone antimicrobial residues in lettuce, cucumber and spinach is developed. The procedure entails a 6 min ultrasound-assisted extraction (UAE, 3 × 2 min) in an alkaline (2% v/v NH3) aqueous solution containing Mg2+ ions (3 × 6 mL), with no need for organic solvents. The extract is submitted to cleanup on the HLB™ cartridge and the fluoroquinolones are separated and quantified by HPLC-MS/MS in a 10 min chromatographic run, using a small amount of acetonitrile in the mobile phase. The method, entirely developed in real matrices, is validated according to the updated analytical guidelines and provided suitable recoveries in the range of 67–116% and precision (RSD ≤ 20%, n = 3) at different concentrations (15, 70 and 150 ng g−1), with method quantification limits of 2–10 ng g−1. Fluoroquinolones were detected and quantified at concentrations from few to hundreds of nanograms per gram in vegetables from supermarkets, demonstrating the applicability of the method for monitoring residues of these pharmaceuticals.
