“…The most common extraction techniques are liquid–liquid extraction (LLE) and conventional solid‐phase extraction (SPE). In recent years, microextraction techniques (METs), including hollow‐fiber liquid‐phase microextraction (HF‐LPME) (Bahrami et al, 2018), dispersive liquid–liquid microextraction (DLLME) (Gu et al, 2020), solid‐phase microextraction (SPME) (Barua et al, 2008; Pacenti et al, 2008), microextraction by packed sorbent (MEPS) (Kurd et al, 2022; Rahimpoor et al, 2019; Soleimani et al, 2018), as well as purge and trap thermal desorption (PTTD) (Prieto et al, 2000) and ‘dilute‐and‐shoot’ approach have also been developed (Rosa, 2013; Šperlingová et al, 2004). The methods provided good figures of merit, including low detection limits, broad linear range, and appropriate recoveries and precisions.…”

“…MEPS has emerged as a robust, high‐throughput, and simple tool in the determination of chemicals in different biological matrices, such as urine, plasma, and saliva (Abdel‐Rehim, 2011; Moein et al, 2015; Pereira et al, 2013; Silva et al, 2014). Recently, MEPS has been used to determine urinary MA (Kurd et al, 2022; Rahimpoor et al, 2019; Soleimani et al, 2018). In these methods, molecular imprinting polymers (MIPs) in MEPS (MIMEPS) (Soleimani et al, 2018), zirconium‐based metal organic frameworks (MOF) in MEPS (MOF–MEPS) (Rahimpoor et al, 2019), or covalent organic frameworks (COFs) in MEPS (COF–MEPS) (Kurd et al, 2022) have been used.…”

Briefly, a 250 μL Hamilton syringe is packed with about 4 mg of the MIPs.…”

“…Although SPE overcomes some drawbacks of LLE methods and is welcomed by researchers for bioanalysis, the lack of selectivity, especially when using conventional sorbents, is its main limitation. Also, when compared against METs (Bahrami et al, 2018; Barua et al, 2008; Gu et al, 2020; Kurd et al, 2022; Pacenti et al, 2008; Rahimpoor et al, 2019; Soleimani et al, 2018), SPE methods are time‐consuming (about five times) and involve higher consumption of sorbents (about 125–250 times) and organic solvents (up to 10 times). Thus, the solvent volume for analyte elution is relatively high (several milliliters) and is not in convergence with that needed for analysis by sophisticated analytical instruments that require much fewer sample volumes (several microliters).…”

We reviewed the toxicokinetics of styrene to introduce reliable surrogates for the biological monitoring of styrene workers. We have also discussed the extraction techniques and analytical methods of styrene and its metabolites. Sample preparation is the main bottleneck of the analytical techniques for styrene and its metabolites. Although some microextraction methods have been developed to overcome such disadvantages, some still have limitations such as long extraction time, fiber swelling and breakage, and the cost and the limited lifetime of the fiber. Among all, microextraction by packed sorbents, coupled with HPLC with ultraviolet detection (MEPS‐HPLC‐UV), can be the method of choice for determining styrene metabolites. Few studies investigated unchanged styrene in breath samples. Chemical determination of styrene in exhaled breath provides new insights into organ toxicity in workers with inhalation exposures and can be considered a fascinating tool in risk assessment strategies. Taking blood samples is invasive and less accepted by workers. In contrast, breath analysis is the most attractive method for workers because breath samples are easy to collect and non‐invasive, and sample collection does not require the transfer of workers to health facilities. Therefore, developing selective and sensitive methods for determining styrene in breath samples is recommended for future studies.

The application of green microextraction techniques (METs) is constantly being developed in different areas including pharmaceutical, forensic, food and environmental analysis. However, they are less used in biological monitoring of workers in occupational settings. Developing valid extraction methods and analytical techniques for the determination of occupational indicators plays a critical role in the management of workers’ exposure to chemicals in workplaces. Microextraction techniques have become increasingly important because they are inexpensive, robust and environmentally friendly. This study aimed to provide a comprehensive review and interpret the applications of METs and novel sorbents and liquids in biological monitoring. Future perspectives and occupational indicators that METs have not yet been developed for are also discussed.

Covalent organic frameworks (COFs) stand for a class of emerging crystalline porous organic materials, which are ingeniously constructed with organic units through strong covalent bonds. Their excellent design capabilities, and uniform and tunable pore structure make them potential materials for various applications. With the continuous development of synthesis technique and nanoscience, COFs have been successfully combined with a variety of functional materials to form COFs‐based composites with superior performance than individual components. This paper offers an overview of the development of different types of COFs‐based composites reported so far, with particular focus on the applications of COFs‐based composites. Moreover, the challenges and future development prospects of COFs‐based composites are presented. We anticipate that the review will provide some inspiration for the further development of COFs‐based composites.
