To build such a large inventories of macro-litter items, the authors compiled a total of 36 datasets providing counts of litter by item typology in river waters and riverbed, shoreline, nearshore waters (<100 km from shoreline) and nearshore seafloor (<100 m depth, <100 km from shoreline), open waters (>100 km from shoreline) and deep seafloor (>100 m depth, >100 km from shoreline).\n\nThese litter items were classified according to their material composition, type of product and probable origin.\n\nOn average, 80% of the items were made of plastic, followed by metal (7% ± 7%), glass (5% ± 6%) and fabric (3% ± 3%)."},"dimensions":{"years":{"values":[{"id":2021}]},"entities":{"values":[{"id":335997,"name":"Cans (drink)","code":null},{"id":37878,"name":"Clothing","code":null},{"id":335979,"name":"Fishing net","code":null},{"id":335980,"name":"Fishing related","code":null},{"id":336000,"name":"Food containers","code":null},{"id":335982,"name":"Glass bottles","code":null},{"id":336001,"name":"Industrial packaging","code":null},{"id":335986,"name":"Plastic bags","code":null},{"id":335987,"name":"Plastic bottles","code":null},{"id":335993,"name":"Synthetic rope","code":null}]}},"origins":[]}
