    Occurrence of microplastics including tire wear particles in northern Atlantic air measured by high-volume samplers in summer 2021 (2023)

    Description: This data set provides mass quantitative data of microplastics (MP) including tire wear particles (TWP) in northern Atlantic air. Air samples were taken with two different active air sampling devices (low- and high-volume samplers) during seven transects on a research cruise along the Norwegian coast up to Bear Island. Identification and quantification of MP was performed with pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS). More information about the measurement technique is found in the related paper (Goßmann et al., 2023; doi:10.1038/s41467-023-39340-5). MP was detected in all transects (max. 37.5 ng m-3). Particularly interesting was the ubiquity of the polyethylene terephthalate cluster (C-PET, max. 1.5 ng m-3). TWP was detected only twice, but in comparably high concentrations (max. 35 ng m-3). A close relationship of C-PET occurrence and possible re-emission processes from the ocean were suspected. The results for some polymer clusters had to be excluded due to sampling related interferences. The respective background is discussed in the related publication. The indicator used for identification and quantification of the polyvinyl chloride cluster (C-PVC) is rather unspecific. Therefore, C-PVC might be interfered by additional anthropogenic sources and the given C-PVC concentration only represents an order of magnitude.

    Microplastics and nanoplastics in the marine-atmosphere environment (2022)
    Nature Research
    Details
    Publication Date: 2024-02-07
    Description: The discovery of atmospheric micro(nano)plastic transport and ocean–atmosphere exchange points to a highly complex marine plastic cycle, with negative implications for human and ecosystem health. Yet, observations are currently limited. In this Perspective, we quantify the processes and fluxes of the marine-atmospheric micro(nano)plastic cycle, with the aim of highlighting the remaining unknowns in atmospheric micro(nano)plastic transport. Between 0.013 and 25 million metric tons per year of micro(nano)plastics are potentially being transported within the marine atmosphere and deposited in the oceans. However, the high uncertainty in these marine-atmospheric fluxes is related to data limitations and a lack of study intercomparability. To address the uncertainties and remaining knowledge gaps in the marine-atmospheric micro(nano)plastic cycle, we propose a future global marine-atmospheric micro(nano)plastic observation strategy, incorporating novel sampling methods and the creation of a comparable, harmonized and global data set. Together with long-term observations and intensive investigations, this strategy will help to define the trends in marine-atmospheric pollution and any responses to future policy and management actions.

    Revised historical Northern Hemisphere black carbon emissions based on inverse modeling of ice core records (2023)
    Springer Nature
    In:  EPIC3Nature Communications, Springer Nature, 14(1), pp. 271-271, ISSN: 2041-1723

    Description: Black carbon emitted by incomplete combustion of fossil fuels and biomass has a net warming effect in the atmosphere and reduces the albedo when deposited on ice and snow; accurate knowledge of past emissions is essential to quantify and model associated global climate forcing. Although bottom-up inventories provide historical Black Carbon emission estimates that are widely used in Earth System Models, they are poorly constrained by observations prior to the late 20th century. Here we use an objective inversion technique based on detailed atmospheric transport and deposition modeling to reconstruct 1850 to 2000 emissions from thirteen Northern Hemisphere ice-core records. We find substantial discrepancies between reconstructed Black Carbon emissions and existing bottom-up inventories which do not fully capture the complex spatial-temporal emission patterns. Our findings imply changes to existing historical Black Carbon radiative forcing estimates are necessary, with potential implications for observation-constrained climate sensitivity.
