“…Hollow fiber LPME and some of its modifications such as ion pair HF-LPME have been used in OBM for the determination of lead (Salari et al, 2018), nickel and cobalt (Hsu et al, 2016), muconic acid, MA, hippuric acid and methyl hippuric acid (Bahrami et al, 2017(Bahrami et al, , 2018Ghamari et al, 2016Ghamari et al, , 2017 and pyrethroid pesticides (Lin et al, 2011). For instance, an ion paire HF-LPME (IP-HF-LPME) has been developed to extract urinary muconic acid, hippuric acid and MA followed by HPLC-UV analysis.…”

“…Also, some authors have reported difficulties with the very small amounts of solvents and simultaneous extraction of many analytes (Venson et al, 2019). The majority of HF-LPME methods are time consuming with extraction times of between 60 and 150 min (Bahrami et al, 2017(Bahrami et al, , 2018Ghamari et al, 2016;Ghamari et al, 2017;Salari et al, 2018).…”

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.

“…A variety of strategies for preconcentration of lead such as cloud point extraction (CPE) (Mohammadi et al 2016), dispersive liquid-liquid microextraction (DLLME) (Mandlate et al 2017), hollow fiber-based liquid phase microextraction (LPME) (Salari et al 2018) and solid phase extraction (SPE) (Khan et al 2016) have been developed to overcome interference effects from sample matrices. SPE is one of the most significant preconcentration strategy among them because it provides high preconcentration factor, low extraction period and low cost.…”

In this paper, a sensitive and simple zirconium nanoparticles (Zr-NPs) based vortex assisted ligandless dispersive solid phase extraction (VA-LDSPE) method was developed for the preconcentration of lead from wastewater samples for the determination by slotted quartz tube-flame atomic absorption spectrometry (SQT-FAAS). Zr-NPs were synthesized using zirconium (IV) chloride salt as a starting material through a simple reduction process with sodium borohydride, and used as selective adsorbent for the extraction of lead ions from aqueous medium. Single variant experiments were carried out for all optimizations of sorption/desorption steps including pH of solution, amount of nanoparticles, mixing type/period and eluent type. An SQT with five round slots was placed onto the burner of FAAS to increase the interaction between lead atoms and light from radiation source to enhance the absorbance signals. Under the determined optimum conditions, analytical figures of merit were evaluated and the limit of detection and quantification (LOD/LOQ) values were calculated as 5.2 and 17.3 µg L − 1 , respectively. The developed method showed a linear calibration range between 25 and 250 µg L − 1 with a good regression coefficient value (0.9995). Recovery studies were also performed with domestic wastewater samples spiked at three concentrations and percent recovery values obtained in the range of 97%-102% validated the developed method's applicability and accuracy.

Analysis of biological samples is affected by interfering substances with chemical properties similar to those of the target analytes, such as drugs. Biological samples such as whole blood, plasma, serum, urine and saliva must be properly processed for separation, purification, enrichment and chemical modification to meet the requirements of the analytical instruments. This causes the sample preparation stage to be of undeniable importance in the analysis of such samples through methods such as microextraction techniques. The scope of this review will cover a comprehensive summary of available literature data on microextraction techniques playing a key role for analytical purposes, methods of their implementation in common biological samples, and finally, the most recent examples of application of microextraction techniques in preconcentration of analytes from urine, blood and saliva samples. The objectives and merits of each microextration technique are carefully described in detail with respect to the nature of the biological samples. This review presents the most recent and innovative work published on microextraction application in common biological samples, mostly focused on original studies reported from 2017 to date. The main sections of this review comprise an introduction to the microextraction techniques supported by recent application studies involving quantitative and qualitative results and summaries of the most significant, recently published applications of microextracion methods in biological samples. This article considers recent applications of several microextraction techniques in the field of sample preparation for biological samples including urine, blood and saliva, with consideration for extraction techniques, sample preparation and instrumental detection systems.
