“…Microfiber size also increases in finished fabrics, with larger sizes of 250 to 400 μm and an increase in microfibers >400 μm (Figure b–d, Figures S11–S14). − Greige fabric refers to fabric that has just been made and contains a large amount of unfixed fibers. When greige fabric is washed, the unfixed fibers are washed away, resulting in the release of shorter microfibers.…”

“…Additionally, Zhengzhou serves as a significant inland textile production hub in China, thereby constituting a crucial origin of fibrous MPs. Studies have also demonstrated that domestic laundry and textile manufacturing in industrial facilities can generate substantial quantities of fibers, exerting a notable influence on the morphology of MPs [41][42][43]. WWTP-C situated in the outskirts, receives sewage that is conveyed through long-distance pipelines.…”

Microplastics have been widely detected in wastewater treatment plants, but there is still a significant dearth of research data on the removal efficiency of microplastics in such plants. The present study focused on three wastewater treatment plants situated in Zhengzhou, China. On-site sampling and Raman spectrum detection techniques were employed to identify microplastics in both wastewater and sludge samples, while the removal efficiency of microplastics was quantified for each plant. Results showed that the abundance of microplastics in influent exhibited ranging from 147.5 ± 2.6 to 288.8 ± 11.8 n/L, while the range in sludge samples was from 12,024.7 ± 1737.0 n/kgdw to 20,818.4 ± 5662.0 n/kgdw. The removal efficiencies of microplastics in the three WWTPs ranged from 76.2% to 91.2%. The primary components of microplastics were generally identified as fibers ranging in size from 10 to 100 μm. The samples collectively exhibited a total of seven distinct colors, with the predominant proportion being transparent. Polypropylene was the polymer type with the highest proportion. The sludge in WWTPs plays a pivotal role in the accumulation of MPs from wastewater bodies, necessitating increased attention toward its proper disposal in future endeavors.

“…Sources related to industrial processes and other non-domestic waters can differ between systems. Examples of such sources are landfill leachate (Paper II) and textile industries (Grillo et al, 2023). Emissions of microplastics from enterprises to the WWTP were estimated to be small in comparison with those from households (Paper II).…”
