Levels, composition and fate of microplastics (MPs) were investigated along different compartments of a secondary wastewater treatment plant (WWTP) with nutrient removal on the northern Sea of Marmara coast (Istanbul, Turkey). When all samples were combined, fibers were found to be the most dominant particles, followed by hard fragments. 500–1000 μm and 1000–2000 μm were the most common size ranges for wastewater and sludge, respectively. Rate of removal differed for sizes and shapes of the particles combined. Hard fragments of <500 μm and fibers of size ranges 250–500 μm and 1000–2000 μm were more successfully removed within the WWTP. Size averages increased throughout the WWTP units. 84.6–93.0% removal was achieved for grab and 3-hr composite samples. Despite the high removal rates of the WWTP, 2,934 × 106 microplastic particles/d were released in the effluent to the Sea of Marmara. Our results show that the Ambarlı WWTP considerably contributes to microplastics contamination in the Sea of Marmara since the plant has a high operating capacity.

Fate and Effects of Polyethylene Terephthalate (PET) Microplastics During Anaerobic Digestion of Disintegrated Sludge Hatinoğlu, Makbule Dilara; Sanin, Faika Dilek; Department of Environmental Engineering (2021-12-24) Modern wastewater treatment plants effectively remove microplastics (MPs) from wastewater but unfortunately concentrate them in sludge. Anaerobic digesters were recently reported to be affected by MPs. Despite their resilience to natural degradation, polyethylene terephthalate (PET) plastics have inherent weaknesses to alkali and thermal conditions and become more susceptible to biodegradation if exposed to them. Sludge disintegration practices aiming to increase the biogas production by disrupting sludge’s...
Evaluation of the hazardous waste landfill cap system design and clay layer thickness criteria of the Turkish Regulation on the Control of Hazardous Waste (RCHW) using the Hydrological Evaluation of Landfill Performance (HELP) model Piskin, F. Yalcin; Demirer, Göksel Niyazi (Inderscience Publishers, 2007-01-01) The hazardous waste landfill design criteria of the Turkish Regulation on the Control of Hazardous Waste (RCHW) was evaluated in this study. In the first part of the study, Hydrologic Evaluation of Landfill Performance (HELP) model was used to determine the significance of different components of the hazardous waste landfill cap system as required by the Turkish RCHW. In the second part of the study, the top and bottom clay layer thickness requirement of the Turkish RCHW was evaluated by running the HELP mo...
Modeling of lithology induced chemical anomalies in the aquifer systems of the Kazan Trona deposit area, Ankara, Turkey Çamur, Mehmet Zeki; Yazıcıgil, Hasan (2008-04-01) The study was carried out in order to investigate existing hydrogeochemical relationships between groundwater environment and geological units in the Kazan trona deposit area, Ankara, Turkey. Evaluations indicate that concentrations of alkalinity, boron, chloride and sodium in the upgradient groundwater of the Eocene sedimentary units gradually increase toward downgradient by the interactions of saline minerals (searlesite, shortite, northupite and pyrite) present in the secondary structures (microfractures...
Evaluation of air quality over the Black Sea Major ionic composition of rainwater Omer, Alagha; Tuncel, Süleyman Gürdal (2003-02-01) This article attempts to put the light on the air quality of the Black Sea region of Turkey. In addition to that, it endeavors to locate the possible sources of the different pollutants at local, regional and long range transported scales. About 196 rainwater samples were collected over the Black Sea region of Amasra between 1995 and 1999, and analyzed for major ions and trace elements using spectrophotometric techniques. Andersen wet only rain samples were used to collect rain events, where the rain sample...
Assessment of artificial aquifer recharge potential in the Kucuk Menderes River Basin, Turkey Sayit, Ayse Peksezer; Yazıcıgil, Hasan (2012-06-01) The Kucuk Menderes River Basin in western Turkey has been facing continuous groundwater-level decline for decades. Previous studies have suggested that, to avoid aquifer depletion in the basin, artificial recharge structures should be constructed. To assess artificial aquifer recharge potential in one of the subbasins, a two-dimensional (2-D) groundwater model was set up using SEEP/W software. The material functions and parameters used in the model for both saturated and unsaturated conditions were taken fr...
