Data underlying the publication: Catchment scale assessment of macroplastic pollution in the Odaw river, Ghana

This database is the supplementary material for the scientific paper in preparation: Catchment scale assessment of macroplastic pollution in the Odaw river, Ghana. The database contains the field data of monitored and sampled litter (macroplastics and non plastics) in the river, on land, and at the riverbank at ten locations within the study area over the sampling period ( between 11-23 December, 2021). Since the

counted macroplastic items were categorised into the aggregated macroplastic polymer types, the file also contains the categorisation of the detailed items (River Ospar list ) into the macroplastic polymer types.
