Replication data for: Cross-ecosystem transfer of microplastics via emergent aquatic insects to riparian spiders in a municipal wastewater-impacted system

These datasets accompany a paper published in Environmental Pollution titled "Cross-ecosystem transfer of microplastics via emergent aquatic insects to riparian spiders in a municipal wastewater-impacted system." The data include microplastic concentration, shape, colour, size, and chemical confirmation of particles found in larval and adult aquatic insects and spiders collected upstream and downstream of eight wastewater treatment plants in the Grand River watershed (Ontario, Canada), as well as data used to assess trophic transfer and trophic transfer factors (TTFs) across aquatic and riparian food webs.
