Summary

Scientists tested how tiny water fleas (a key species for studying pollution effects) responded to different types and sizes of plastic particles, looking at survival, swimming, and reproduction over time. This kind of research matters because it helps us understand how the growing amount of micro- and nanoplastics in our water might affect living things—and since these plastics also show up in the food we eat and water we drink, studies like this build the foundation for understanding potential risks to human health, too. Note that this particular paper is a data-sharing resource rather than a full analysis of health outcomes, meant to help other researchers verify and reuse the findings.

This dataset contains the raw data and metadata supporting the manuscript "Chronic reproductive and behavioural endpoints reveal polymer- and size-dependent responses to micro- and nanoplastics in Daphnia magna". It includes physicochemical characterization of the tested particles and raw data from acute immobilization (48 h), swimming behaviour (48 h), and chronic reproduction (21 d) assays following exposure to polystyrene (PS) and polyethylene (PE) micro- and nanoplastics. Swimming behaviour validation data obtained using silver (Ag) and titanium dioxide (TiO₂) nanoparticles are also included. The dataset is provided to support reproducibility and facilitate data reuse and meta-analyses.
