Microplastic pollution in Cevdet Dündar Pond: first observation on freshwater of Turkey
Summary
This study reports the first documented occurrence of microplastic pollution in Cevdet Dundar Pond, a Turkish freshwater body. Microplastics of various shapes and polymer types were found, establishing a baseline for freshwater microplastic monitoring in the region.
Microplastic pollution has increased rapidly over recent decades and accepted as an emerging thread. However, the effects and dimensions of microplastic pollution on aquatic ecosystems have not been fully understood yet. Most of these few studies have been carried out in marine ecosystems and the number of studies on freshwater are very limited. This is the first study represents a detailed investigation of microplastic pollution in a freshwater body in Turkey. In this study, microplastic (<5 mm) pollution level of surface water samples taken from Cevdet Pond (Yozgat/Turkey) was investigated. Water samples (150 L) were taken from 5 stations and microplastic particles were extracted via density separation method. Random particles were examined both visually and spectrophotometrically (-Raman). According to station averages, there were 233 microplastic particles in 1 m3 of the pond water. Highest number of MP particles observed in 100-250 m (56%) size class. Most abundant microplastic type and colour are fiber (91%) and blue (36%) respectively. Polypropylene (50%) and polyethylene (40%) were the most abundant type of polymers according to -Raman analysis. The presence of microplastic pollution in an area where human impact is relatively low, indicates the prevalence of microplastic pollution in freshwater ecosystems.

Microplastic pollution and ecological risk assessment of a pond ecosystem
Researchers quantified and characterized microplastics in a freshwater pond in Turkey, finding particles at all five sampling stations across multiple size classes. The study contributes baseline data on microplastic pollution in inland freshwater ecosystems in the region, where such monitoring is still limited despite the potential for drinking water and wildlife exposure.
Characterization of microplastics in sediments and surface waters of Turkish lakes
Researchers surveyed seven lakes in Turkey and found microplastics in all of them, with polyethylene and polypropylene being the most common types. Human activities like tourism, fishing, and urban waste disposal were identified as major sources, showing that even protected lake areas are contaminated with plastic particles that can enter drinking water supplies.

Researchers found 2,444 microplastics across three freshwater systems near Antalya Bay, Turkey, with fibers (57%) and fragments (33%) dominating, and polyethylene and polypropylene as the most common polymers, showing a homogeneous pollution pattern across all sampling sites.
Determination of Seasonal Microplastic pollutıon Variation in Aquatic Environments: Case Study from İskenderun Technical University Pond
Microplastic abundance in a university pond in Turkey ranged from 0.5 to 10.8 particles per liter and varied significantly by season, with rainfall and stormwater runoff being the main drivers of contamination. Black polyester and polypropylene fibers under 1 mm were the most common type found. The study demonstrates that even small, semi-enclosed inland water bodies can accumulate significant microplastic loads and that seasonal monitoring is needed to accurately characterize contamination levels.
