“…This leads to the accumulation of plastic waste in various environments, particularly freshwater and marine habitats (Cole et al, 2011). Accumulated plastic waste can be transported to seas through various ways such as rivers, agricultural irrigation, discharge waters of wastewater treatment plants, heavy rains, oods, and winds (Dehghani et al, 2017; R. Gündoğdu et al, 2022; S. Gündoğdu et al, 2018;Talvitie et al, 2017). Plastic waste that is transported from one environment to another through various ways turns into microplastics (MPs) that are smaller than 5 mm due to physical, chemical, and biological factors over time (secondary MPs) (Mihai et al, 2022;Viaroli et al, 2022).…”

“…The color variety of MPs may be related to the colors of the original plastic waste or may change due to weather conditions(Pastorelli et al, 2014).The polymer types identi ed by µ-Raman for the MPs detected were examined and found to be compatible with the polymer types that have the largest share in global plastic production (PE, PET, PP, and PS) (Plastics Europe, 2021). Additionally, it is noted that the source of terrestrial plastic pollution, particularly in non-urban and agricultural areas, is the use of agricultural plastics (R Gündoğdu et al, 2022)…”

Microplastics have become ubiquitous pollutants everywhere. However, there is still limited data on the presence of microplastics in some ecosystem compartments. Groundwater resources, particularly thermal waters, are also an environment with little-known microplastic pollution. In this study, the presence of microplastics in thermal water resources used for geothermal applications in Kütahya region was investigated for the first time in Turkey. In the study, 3 liters of sample per location were taken from 21 thermal points in 9 regions in amber glass bottles of 1.5 liters each. The samples were filtered directly through cellulose acetate filters with a 0.45 µm filter paper using a vacuum pump. The filter papers were subjected to microscopic examination and µ-Raman analysis directly. As a result of microscopic examination, a total of 88 microplastic-like particles were detected, and µ-Raman analysis confirmed that 68.11% of them were microplastics. Thus, an average of 0.85 ± 0.71 MPs/L (850 MPs/m3) was detected from all locations. The highest microplastic concentration was found at the ST-8 station with 4.88 ± 2.98 MPs/L. No particles were found in the ST-7, ST-10, and ST-20 stations. Of the particles detected, 50.0% were fiber, 10.2% were film, and 39.8% were fragment types. The µ-Raman analysis confirmed that the polymers found were cellulose, PE, PET, PP, PS, and PET, and the most commonly found polymer was PE at 22.2%. The results obtained from this first-ever study of microplastics in geothermal waters demonstrate that microplastics can be found in low amounts in thermal groundwater resources.

“…Polymer is a traditional material with macromolecular structure that is widely used in our daily life due to its light weight, low cost, and chemical stability [ 1 ]. The processing of polymer materials into polymer film materials that are indispensable in our lives has a wide range of applications, such as greenhouses [ 2 , 3 ], packaging [ 4 ], antimicrobials [ 5 ], and agricultural films [ 6 , 7 ]. To further expand the applications of polymeric film materials, and to obtain greater performance advantages than can be obtained by using each component alone, solid fillers and additives are often added to produce mixed matrix membranes (MMMs) [ 8 ].…”

The incorporation of different functional fillers has been widely used to improve the properties of polymeric materials. The polyhydroxy structure of PVA with excellent film-forming ability can be easily combined with organic/inorganic multifunctional compounds, and such an interesting combining phenomenon can create a variety of functional materials in the field of materials science. The composite membrane material obtained by combining MOF material with high porosity, specific surface area, and adjustable structure with PVA, a non-toxic and low-cost polymer material with good solubility and biodegradability, can combine the processability of PVA with the excellent performance of porous filler MOFs, solving the problem that the poor machinability of MOFs and the difficulty of recycling limit the practical application of powdered MOFs and improving the physicochemical properties of PVA, maximizing the advantages of the material to develop a wider range of applications. Firstly, we systematically summarize the preparation of MOF/PVA composite membrane materials using solution casting, electrostatic spinning, and other different methods for such excellent properties, in addition to discussing in detail the various applications of MOF/PVA composite membranes in water treatment, sensing, air purification, separation, antibacterials, and so on. Finally, we conclude with a discussion of the difficulties that need to be overcome during the film formation process to affect the performance of the composite film and offer encouraging solutions.
