Geochemical Signatures in Plastic Debris from the Curonian Lagoon, Lithuania

This dataset contains raw geochemical data on elemental accumulation in weathered plastic debris collected from the vicinity of the Curonian Lagoon, Lithuania. The samples were analyzed for 32 elements using inductively coupled plasma–mass spectrometry (ICP-MS), and polymer types were identified using standard spectroscopic methods. The dataset includes elemental concentrations, polymer classification, and associated metadata required for reproducibility and reuse. These data support the findings reported in the associated PLOS ONE article and are provided as a supplement to the publication.
