“…Micro/nanoplastics (MNPs), defined as polymer particulate matter of a size less than 5 mm, have emerged as a significant environmental concern due to their pervasive presence and detrimental impact on ecosystems worldwide. , MNPs originate from diverse sources, such as fragmentation of larger plastic items, shedding of microfibers from textiles, and degradation of plastic debris, among many others. The hydrophobicity, high surface area, and small size of MNPs enable them to concentrate and transport pollutants into the ecosystem and biological organs, leading to potential adverse health effects on humans and other organisms. − Thus, monitoring of MNPs in environmental media is imperative for assessments of their ecological impact and potential human health risks.…”

Determinations of micro/nanoplastics (MNPs) in environmental samples are essential to assess the extent of their presence in the environment and their potential impact on ecosystems and human health. With the aim to provide a sensitive method with simplified pretreatment steps, cooling-assisted solid-phase microextraction (CA-SPME) coupled to gas chromatography−mass spectrometry (GC-MS) is proposed as a new approach to quantify mass concentrations of MNPs in water and soil samples. The herein proposed CA-SPME method offers the unique advantage of integrating the thermal decomposition of MNPs and enrichment of signature compounds into one step. Poly(methyl methacrylate) (PMMA) was used as a model substance to verify the method performance in this work. Theoretical insights demonstrated that pyrolysis is the rate-determining step during the extraction process and that PMMA is effectively decomposed at 350 °C with an estimated incubation time of 13 min. Eight compounds were identified in the pyrolysis products by CA-SPME-GC-MS with the use of a DVB/ CAR/PDMS coating, wherein methyl methacrylate was considered as the best indicator and dimethyl 2-methylenesuccinate was selected as the confirmation compound. Under the optimized conditions, the proposed method exhibited wide linearity (0.5−2000 μg for water and 5−1000 μg for soil) and high sensitivity, with limits of detection of 0.014 and 0.28 μg for water and soil, respectively. Finally, the proposed method was successfully applied for determinations of PMMA MNPs in real water and soil samples with satisfactory recoveries attained. The method only required the employment of a filter membrane for water analysis, while soil samples were analyzed directly without any pretreatment. The solvent-free approach, straightforward operation, and high sensitivity of the proposed method show great potential for the analysis of MNPs in different environmental samples.

“…Microplastics are defined as synthetic organic polymer particles with a size (or, more precisely, a maximum size) <5 mm [1]. The problem of environmental pollution caused by microplastic accumulation in various ecosystems draws attention from the whole world [1][2][3][4] and Ukraine specifically [5,6].…”
