Pollution sources of macro- and microplastics

Model characteristics

  • Model name: MARINA-Plastics
  • Version: Global-1.0
  • Application: Global
  • Scales: sub-basins and annual
  • Period: 2010-2100
  • Pollutants: macro- (>5mm) and microplastics (<5mm)
  • Sources: point (sewage containing plastics from laundry, car tyres, household dust and personal care products) and diffuse (mismanaged solid waste)
  • Main inputs: population connected to sewage systems, removal efficiencies, production of mismanaged waste, consumption/production rates for personal care products, car tyres, dust and laundry, hydrology
  • Main outputs: river export of macro- and microplastics by source and sub-basin
