Microplastics Across Interconnected Aquatic Matrices: A Comparative Study of Marine, Riverine, and Wastewater Matrices in Northern Greece
AI summary Read the abstract
Scientists studied tiny plastic particles (microplastics) in seawater, rivers, and wastewater treatment plants in Northern Greece to understand how much plastic pollution exists in the region's water systems. They developed a reliable method to measure these microscopic plastic pieces and established baseline pollution levels that can help authorities create better strategies to reduce plastic contamination. This matters because microplastics can enter our drinking water and food chain, and understanding where they're most concentrated helps protect both environmental and human health.
This study provides an integrated assessment of microplastic (MP) presence across marine, riverine, and wastewater treatment plant samples in Northern Greece—a region where such data are largely lacking. The proposed analytical workflow, combining microscopy and Py–GC/MS, offers a transferable framework for monitoring programs in Mediterranean coastal zones. The findings offer valuable insights for environmental authorities in establishing baseline MP levels and guiding mitigation strategies for regional water/wastewater quality management.

Researchers studied tiny plastic particles (microplastics) in seawater, rivers, and wastewater treatment plants in Northern Greece to see how much plastic pollution exists in the region's water systems. They developed a reliable method to measure these microscopic plastic pieces, which can enter our food chain through seafood and drinking water. This baseline data will help authorities track plastic pollution levels and develop strategies to reduce microplastics in water that could eventually affect human health.
Microplastics Across Interconnected Aquatic Matrices: A Comparative Study of Marine, Riverine, and Wastewater Matrices in Northern Greece
AI summary Read the abstract
This study provided the first comprehensive evaluation of microplastics across three interconnected aquatic matrices—seawater, river water, and wastewater—in northern Greece. MP concentrations were highest in wastewater and decreased downstream, with fibres dominating all matrices, confirming wastewater as a primary MP source to receiving waters.
Comparative Distribution of Microplastics in Different Inland Aquatic Ecosystems
AI summary Read the abstract
Researchers surveyed microplastic pollution in seven Greek inland water bodies differing in morphology and human impact, finding microplastics (predominantly fibers) in all samples with abundances from 0.60 particles/m³, highlighting contamination even in less impacted freshwater systems.
Variations in microplastic abundance, sizes, and characteristics in Kizilirmak Delta
AI summary Read the abstract
Scientists studying Turkey's Kizilirmak Delta found that rivers carry much higher levels of tiny plastic particles (microplastics) than nearby lagoons or the seabed, suggesting rivers act as major highways funneling plastic pollution into coastal ecosystems. This matters because these waterways often connect to fishing grounds and drinking water sources, meaning tracking how microplastics travel from rivers to the sea could help identify where pollution enters our food and water supply, and where cleanup efforts should focus first.
Comparative Distribution of Microplastics in Different Inland Aquatic Ecosystems
AI summary Read the abstract
Researchers sampled seven Greek inland aquatic ecosystems of varying types and found microplastics in all locations, with fibers dominating (0.47–149.4 items/m³) and higher concentrations in vertical than surface samples, indicating that morphology, trophic status, and anthropogenic pressure influence distribution.
