Pollution due to COVID-19 measures

Model characteristics

  • Model name: MARINA-Multi
  • Version: Global-3.0
  • Application: Global
  • Scales: sub-basins and annual
  • Period: 2020
  • Pollutants: triclosan, microplastics, macroplastics and diclofenac
  • Sources: point sources (sewage) and diffuse sources (mismanaged solid waste)
  • Main inputs: mismanaged waste, population, consumption of diclofenac, plastics and triclosan, excretion rate of diclofenac, sewage systems
  • Main outputs: inputs of multiple pollutants to rivers by source and sub-basin
