Abstract

Plastics in the marine environment have become a major concern because of their persistence at sea, and adverse consequences to marine life and potentially human health. Implementing mitigation strategies requires an understanding and quantification of marine plastic sources, taking spatial and temporal variability into account. Here we present a global model of plastic inputs from rivers into oceans based on waste management, population density and hydrological information. Our model is calibrated against measurements available in the literature. We estimate that between 1.15 and 2.41 million tonnes of plastic waste currently enters the ocean every year from rivers, with over 74% of emissions occurring between May and October. The top 20 polluting rivers, mostly located in Asia, account for 67% of the global total. The findings of this study provide baseline data for ocean plastic mass balance exercises, and assist in prioritizing future plastic debris monitoring and mitigation strategies.

  • Microplastics are now ubiquitous in soil, rivers and lakes, and oceans.

  • Considering physical boundaries may help in understanding the generation of plastic waste in watersheds and indirectly sources of plastic to the ocean.

    “The analysis of our results may not only be constrained to political boundaries as in this study, we show how considering physical boundaries may help in understanding the generation of plastic waste in watersheds and indirectly sources of plastic to the ocean (Lebreton et al., 2017;Schmidt et al., 2017).”

  • Through runoff, winds, and gravity, plastic debris slowly makes its way downhill and enters the sea from coastal environments and through rivers.

    “Through runoff, winds, and gravity, plastic debris slowly makes its way downhill and enters the sea from coastal environments (Jambeck et al., 2015) and through rivers (Lebreton et al., 2017).”

  • River plastic discharge alone has been estimated at 0.4 to 4 Mt per year and >2/3 of the global total of riverine plastic in the ocean stems from the top 10-20 polluting rivers.

    “However, river plastic discharge alone has been estimated with 0.4 to 4 Mt per year and > 2 3 rd of the global total of riverine plastic in the ocean stems from the top 10-20 polluting rivers.49,50”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
