"Microplastic concentration, characterization, and size distribution in the Delaware Bay estuary." Chemosphere (2024): 142523. Data include polymer counts by individual polymer type, particle concentrations, and other field observations. As described in Nitzberg et al, particles retained on 500um sieves post-wet peroxide oxidation and density separation with saturated sodium chloride were analyzed via Fourier Infrared Spectroscopy (FTIR) with Attenuated total reflectance (ATR) or tranmittance. Manufactured polymers >5000um were classified as macroplastics. See https://doi.org/10.1016/j.chemosphere.2024.142523 for details.
