Summary: This study investigated the presence of microplastics (MPs) in agricultural land and textile sludge samples near textile industries in Bangladesh. The MPs content in the soil samples was found to be 2.13 x 104 +/- 0.13 x 104 MPs/kg, while in the textile sludge samples it was 2.92 x 104 +/- 0.14 x 104 MPs/kg. Further research is needed to fully understand the fate and ecological risks of MPs in the soil environment and textile sludge, and necessary actions should be taken to control MP pollution in terrestrial ecosystems.

Summary: This review examines the definition of fibrous microplastics (FMPs), their release during textile washing, retention in wastewater treatment plants (WWTPs), and subsequent emission to the aquatic environment. Based on existing data, it estimates that the annual release of FMPs from synthetic textile washing is in the range of 50.6-1180 kg per 100,000 population, with approximately 95% of it being discharged into receiving waters via WWTPs.

Summary: This study compared two analytical methods for microplastic detection using micro Fourier Transform Infrared Spectroscopy (mu FTIR) imaging. The methods differed in terms of MP isolation procedures, optical substrate, and detection limit. The two methods resulted in different MP abundance and mass estimates, but not MP characteristics. The study also found that the variability between individual samples was larger than the difference caused by the methods.

Summary: This study investigated the presence of microplastics (MPs) in the Taipu River in the Yangtze River Delta, China, where there is a highly developed textile industry. The results showed widespread occurrence of MPs particles in the river, with higher concentrations in surface waters and a strong association with textile manufacturing zones. The major composition of MPs was transparent fibers, mainly made of polyethylene terephthalate (PET). The study also highlighted the presence of polyvinyl acetate (PVAC), which is used in fabric coating and nonwoven fabrics. Although the risk assessment revealed a light to moderate risk of MPs pollution in the Taipu River, the study emphasized the need for controlling textile wastewater and implementing cleaner production practices in the textile industry.

Summary: Anthropogenic development has led to the release of microplastics (MPs) and their associated heavy metals into the environment, potentially causing toxic effects on ecosystems. This study evaluated the factors influencing the adsorption capacities of 8 types of MPs on 13 types of heavy metals using a large dataset. The results showed that the types of MPs, heavy metals, and adsorption environments significantly influenced the adsorption capacities, with polyvinyl alcohol (PVA) exhibiting high adsorption capacities for lead (Pb) and cadmium (Cd). Multiple variables such as heavy metal concentration, MP quality, solution amount, adsorption time, and pH regulated the adsorption capacities of MPs for heavy metals.

Summary: This study reveals that the sinking rate of microplastics in a lake environment is influenced by biofilm development, leading to increased density and eventual sedimentation. Smaller particles sink more easily than larger particles, resulting in size-based fractionation during sedimentation in lakes.

Summary: The study on the impact of sea surface microplastic concentration in four tropical bays in central Mexican Pacific found that there was no significant difference in fiber concentration among bays and seasons, while fragment concentration was significantly higher in Manzanillo and Santiago. Raman spectroscopy data revealed different polymer types, and non-metric multidimensional scaling showed distinct microplastic distribution in different bays.

Summary: The textile industry produces innovative and diverse products, but it also causes damage to the environment. Synthetic fibers dominate the industry and release plastic wastes at various scales, posing risks to living organisms. This study aims to find the most effective pretreatment method for reducing organic matters in textile wastewater to detect microplastics and microfibers. The results show that H2O2 is the most efficient chemical for separating organics, while KOH and NaOH cause damages to all polymer types.

Summary: Micellar-enhanced ultrafiltration is a surfactant-based method to remove low concentrations of contaminants from water and wastewater streams, increasing the permeate flux. The parameters influencing MEUF include surfactant types, membranes, pressure, etc. However, the reviewed data indicates gaps in MEUF studies, such as the lack of information regarding important parameters and imprecise measurements of CMC. The challenge for future industrial-scale applications is to study MEUF on a pilot scale using industrial wastewater.

Summary: Certain diseases can be spread through contact with contaminated surfaces. Textile products, due to their structure and composition, provide favorable conditions for pathogens to grow and spread, making them potential sources of contamination. This study investigated the antimicrobial activity of a cotton fabric coated with kaolinite-titania nano-hybrid particles, which showed effective disinfection against both Gram-negative and Gram-positive bacteria.

Summary: Despite the development of alternative fuels and energy sources, the world still heavily relies on petroleum production and extraction. This poses a global challenge in treating oilfield produced water (OPW), as an average of 3 barrels of OPW is produced for every barrel of extracted oil. OPW contains various organic compounds, including recalcitrant naphthenic acids (NAs) that are not efficiently removed by conventional treatment methods. Advanced oxidation processes (AOPs), such as ozonation, photocatalysis, photochemical oxidation, and Fenton-based processes, are considered promising alternatives for degrading resistant organic compounds. This review focuses on discussing the treatment of OPW and the degradation of pollutants using different AOPs, addressing the influencing factors and strategies to enhance AOPs efficiency. The findings suggest that individual processes may have limitations, and current research is exploring the use of combined processes.

Summary: Polymers, which are widely used in modern society, are mainly made from non-renewable petroleum-derived monomers, resulting in pollution. Therefore, it is important to find biodegradable polymers that can be produced and disposed of without generating pollutants. The use of supercritical carbon dioxide instead of organic solvents has shown to be a greener alternative for polymerization processes.
