zizien1019/fragmentation_eccov4r5_mitgcm68o: New release so Zenodo captures it; no content change
AI summary Read the abstract
This entry is actually a code/data repository (not a standalone study) that supports a computer modeling paper tracking how microplastics break into smaller and smaller pieces as they travel through the world's oceans. Understanding this breakdown process matters because tinier plastic fragments are more likely to be ingested by marine life and potentially end up in our food and water — but this specific release is just a technical update to preserve the software, not new health findings.
This repository contains files related to the research paper: "Distribution and Transport of Fragmenting Microplastics in a 3-D Global Eulerian Model" by Tseng et al. 2026 Please refer to the readme file to see how to reproduce the simulation.

AI summary Read the abstract
This entry is a code repository, not the actual study — it contains the computer files scientists used to track how microplastics break down into smaller and smaller pieces as they move through the world's oceans. Understanding where these tiny fragments end up matters because smaller microplastic pieces are more likely to be eaten by marine life, and potentially end up in the seafood we eat. Note: since this is a technical dataset/code release rather than a research paper with results, no specific findings about health impacts are reported here.
FRAGMENT-MNP: A model of micro- and nanoplastic fragmentation in the environment
AI summary Read the abstract
Researchers developed an open-source computer model called FRAGMENT-MNP that simulates how plastic debris breaks down into smaller micro- and nanoplastic particles over time in the environment. The model predicts fragmentation patterns based on the physical properties of different plastics and environmental conditions. This tool gives scientists a new way to understand and forecast how plastic pollution evolves, which is important because particle size affects how plastics move through ecosystems and interact with living organisms.
GEOS-Chem-IGE/hough2026_atmo-plast-emis_sims: v1.0.1
AI summary Read the abstract
This is actually a code repository, not a full research paper — it contains the computer simulation tools used in a related study that recalculated how much microplastic pollution enters the air worldwide. The underlying research suggests that previous estimates of airborne microplastics were too high because they didn't properly account for different measurement methods; using more consistent, size-standardized data shows lower global emissions than earlier studies claimed. This matters because accurately knowing how much microplastic we're breathing in is a key step toward understanding health risks, and overestimating pollution levels could lead to misplaced public concern or policy priorities.
Distribution and Transport of Fragmenting Microplastics in a 3D Global Eulerian Model
AI summary Read the abstract
Scientists built a computer model showing that ocean plastic doesn't just float on the surface, as it breaks into smaller pieces, it loses buoyancy and sinks hundreds of feet deep, spreading far beyond where we can easily see or measure it. This matters because it means the tiniest plastic fragments (small enough to potentially enter our bodies through seafood) are likely accumulating in ocean currents and depths we haven't been tracking well, suggesting our current estimates of microplastic exposure may be incomplete.
Distribution and Transport of Fragmenting Microplastics in a 3D Global Eulerian Model
AI summary Read the abstract
Scientists built a new computer model showing that as ocean plastic breaks into smaller and smaller pieces, it doesn't just float on the surface, it sinks hundreds of meters deep and spreads out, with the tiniest fragments (smaller than a human red blood cell) building up in the centers of major ocean current systems. This matters because these ultra-small plastic particles are the ones most likely to enter marine food webs and eventually end up on our plates, so understanding where they accumulate helps researchers better predict human exposure risks down the line.
