Microscopy Images of Microplastics in Photovoltaic-Covered Irrigation Pond Water

Description

This dataset contains 71 optical microscopy images of suspected microplastic particles collected from water stored in a photovoltaic-covered irrigation pond in Salamanca, Spain, during sampling campaigns conducted between 2024 and 2026. The images include scale references of 100, 200 or 400 µm and show particles with different shapes, sizes and orientations. They were used for manual particle-length measurement and for developing and validating an AI-assisted image-analysis workflow based on automatic scale recognition, SAM2 segmentation, morphological skeletonization and length estimation. Some images contain portions of the grid printed on the filtration membrane, which may interfere with automatic particle segmentation.
