Dataset accompanying the publication "Transport and Retention of Microplastics into gravelly riverbed sediment: A Polymer-Specific Column-Scale Study"
AI summary Read the abstract
Scientists tested how different types of plastic microparticles move through riverbed gravel—similar to how these particles might travel through natural water filtration systems. This matters because rivers often feed into the groundwater we drink, and understanding whether microplastics get trapped in sediment or flow through freely helps us predict how much of this pollution could end up in our water supply. Note: this dataset itself contains raw lab data and images, not the study's actual conclusions—you'd need to check the full paper for what the results mean for water safety.
The dataset in this repository is accompanying the publication "Transport and Retention of Microplastics into gravelly riverbed sediment: A Polymer-Specific Column-Scale Study". The repository contains raw image files of sample filters which were scanned using the fluorescence imaging system ChemiDoc and used to analyse the infiltration behaviour of microplastics consisting of polymer types PET, PP, PS & PVC in the manuscript. In addition, we provide the resulting data from the particle identification and geometric analysis which were derived from the raw data using ImageJ in tabular excel format. The data is structured in folders following the naming of the columns from the manuscript. In addition, we have added breakthrough data for the fluorescein tracer and the sample masses as metadata.

Scientists tested how different types of plastic microparticles move through riverbed gravel—similar to how water filters through rocks in a stream—to see whether these tiny plastics get trapped or flow onward into water supplies. This matters because microplastics in rivers can end up in drinking water sources, and understanding which types of plastic get filtered out naturally versus which travel further helps researchers predict where contamination risks are highest. Note that this particular dataset shares the raw research data itself rather than presenting the full findings, so specific conclusions about health risks would come from the full published study.
Transport and Retention of Microplastics in Gravelly Riverbed Sediments: A Polymer-Specific Column-Scale Study
AI summary Read the abstract
Lab experiments passed water through columns of gravel sediment to see how four types of plastic fragments moved through it. Most plastic particles stayed in the top 10 to 15 cm of gravel, with denser plastics like PET and PVC moving less deep than lighter polystyrene, suggesting particle density affects how far microplastics travel into riverbeds.
