Description

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.
