Occurrence and analysis of microplastics in municipal wastewater, Poland
Summary
Researchers analyzed microplastic contamination in the influent of a large urban wastewater treatment plant in Poland and found an average of about 4 particles per liter. Textile fibers, primarily from clothing, were the most common form of microplastic detected, with polyethylene terephthalate and rubber among the dominant polymer types. The study underscores that laundry and everyday product use are significant sources of microplastic entering the water system.
Microplastics are a growing environmental threat and wastewater treatment plants have been identified as significant conduits for these pollutants. This study addresses microplastic loading in the influent of a large urban wastewater treatment plant, presenting a detailed analysis of their prevalence and characteristics. Our findings reveal a concentration of 4.09 microplastic particles per litre in the tributary. We performed a detailed statistical comparison of the microplastic particles, categorising them by shape, size, colour, and polymer type. Using Fourier transform total reflectance infrared spectroscopy, we identified 13 different polymer types, with polyethylene terephthalate, rubber, and polyethylene predominating. The analysis showed that textile fibres, mainly from clothing, are the most prevalent form of microplastic in wastewater, followed by fragments from the breakdown of larger plastic objects and films. This research highlights the critical need for strategic interventions to mitigate microplastic pollution at municipal sources.

A Survey of Microplastic Pollution from Wastewater Treatment Plant Effluent Within the Lake Champlain Basin
A survey of wastewater treatment plant effluent found that microplastics — primarily fibers from synthetic clothing — pass through treatment processes and are discharged to waterways. The study highlights treated wastewater as a major pathway for microfiber microplastics to enter rivers and coastal waters.
Occurrence and Characteristics of Microplastics in a Wastewater Treatment Plant
Researchers sampled the inflow, outflow, and sludge of a Chinese wastewater treatment plant, finding up to 44 microplastic particles per liter in incoming water — mostly polyester fibers. The plant removed about 96% of microplastics, but the remaining fraction was still discharged into receiving waterways.
Microplastic Types in the Wastewater System—A Comparison of Material Flow-Based Source Estimates and the Measurement-Based Load to a Wastewater Treatment Plant
This study compared model-based estimates of microplastic sources in wastewater with actual measurements at a treatment plant, finding that synthetic textiles were the dominant source of microplastic fibers. The results help prioritize which pollution sources to address first in efforts to reduce microplastics entering waterways from sewage treatment.
Assessing the Occurrence and Distribution of Microplastics in Surface Freshwater and Wastewaters of Latvia and Lithuania
Researchers measured microplastic concentrations in surface water and wastewater across four Baltic cities in Latvia and Lithuania, finding an average of 16.63 particles/L with fibers as the dominant shape and polyethylene terephthalate as the most common polymer, with municipal and hospital wastewater identified as the primary contamination sources.
Microplastics in municipal wastewater treatment plants in Turkey: a comparison of the influent and secondary effluent concentrations
Microplastics were detected in both influent and secondary effluent at two wastewater treatment plants in Turkey, with fibers as the predominant type in both streams. The study confirms that Turkish wastewater systems discharge substantial numbers of microplastic particles into receiving waters, consistent with findings from other countries.
