Summary: Misuse and incorrect disposal of fluoroquinolones (FQs) have resulted in environmental pollution and contamination of FQs in food chains. As a result, researchers have been striving to develop innovative and simple techniques for FQs analysis in real samples, with a focus on micro- and macroscale dispersive solid-phase extraction (DSPE). Recent studies have reported the use of DSPE-based techniques for sample preparation and detection of FQs in various matrices. This study summarizes current FQs detection methods using chromatographic and DSPE-based combinations, and evaluates the advantages and analytical performance of DSPE in detecting trace levels of FQs.

Summary: Despite the benefits of organophosphorus pesticides (OPPs) in controlling diseases and insects, their accumulation in the soil system can pose a serious threat to ecosystems and human health. It is crucial to isolate and preconcentrate OPPs from the soil matrix to achieve reliable detection due to low residue levels and the complexity of the soil. Sample preparation techniques have been reported to improve analytical measurements, including recovery, precision, detection limit, and quantification limit. The efficiency of extraction depends on the interaction between OPPs and the extraction media.
