Microplastics in municipal wastewater treatment plants in Turkey: a comparison of the influent and secondary effluent concentrations
AI summary Read the abstract
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.
Wastewater treatment plants are one of the primary pathways through which microplastics enter aquatic environments. In this study, we have determined the microplastic concentrations of the influent and secondary effluent water of two wastewater treatment plants in Turkey. For this purpose, we have taken samples of the influent and effluent water of Seyhan and Yüreğir wastewater treatment facilities for 6 days in August 2017 and determined their microplastics' content both visually and using μ-Raman spectroscopy. The results showed that the influent of the wastewater treatment contained 1 million-6.5 million particles per day, while the effluent contained 220,000-1.5 million particles per day. The removal rate of microplastics was found to be between 73 and 79%. In total, seven different types of polymers were detected. The most frequently observed polymer type was polyester.

Microplastics composition and load from three wastewater treatment plants discharging into Mersin Bay, north eastern Mediterranean Sea
AI summary Read the abstract
Three wastewater treatment plants discharging into Mersin Bay in the northeastern Mediterranean were found to release significant loads of microplastics into coastal waters, with fibers and fragments as the dominant forms. The study quantifies WWTPs as a measurable source of ongoing microplastic input to Mediterranean marine ecosystems.
Presence of Microplastic in Erzurum Urban Wastewater Treatment Plant
AI summary Read the abstract
Researchers investigated microplastic presence at the inlet and outlet of the Erzurum Urban Wastewater Treatment Plant in Turkey, finding average concentrations of 36,400 MP/m3 in influent and 2,875 MP/m3 in effluent. Tertiary treatment achieved over 90% removal efficiency, while primary and secondary treatment alone proved insufficient for effective microplastic removal.
