Pollutants: macro- (>5mm) and microplastics (<5mm)
Sources: crop production (mulching, greenhouse plastics), point sources (sewage), diffuse sources (mismanaged solid waste)
Main inputs: application rates of plastics for mulching and greenhouses, residue rates of plastics in soils, population connected to sewage systems, removal efficiencies, hydrology
Main outputs: inputs of macro- and microplastics to rivers by source and sub-basin
