Including Impacts of Microplastics in Marine Water and Sediments in Life Cycle Assessment

This repository contains the supplementary information associated with the development of updated characterization factors (CFs) for the physical effects of microplastics (MPs) on marine biota, including impacts in both the water column and sediment compartments.

Including impacts of microplastics in marine water and sediments in life cycle assessment. Journal of Cleaner Production, 520, 146037. https://doi.org/10.1016/j.jclepro.2025.146037 The supplementary information, described in the manuscript, includes: Fate modeling data for MPs across water and sediment compartments, considering variations in polymer type, particle size, and shape. Species Sensitivity Distribution (SSD) datasets, including EC10 values collected from the literature for sediment-dwelling species, used to derive the hazardous concentration for 20% of species (HC20). Exposure and Effect Factor (EEF) calculations for sediments (EEF) CFs for MPs expressed in units compatible with IMPACT World+, ReCiPe or the UNEP-Life Cycle Initiative GLAM: PAF m3 d/kg, PDF m2 yr/kg, PDF yr/kg, species yr/kg for use in life cycle impact assessment (LCIA) Case study results
