• Concentrations in sediment 4 orders of magnitude

greater than at ocean surface

• Average of 13 fibers/50ml sediment

Fibers in deep sea sediment


31/34

Summary

• Microplastics present in every tributary sample to date

(max 11.4 particles/m3, median 1.8 particles/m3)

• Tributary concentrations 10-100 times greater than in Great Lakes

• Relations with flow condition, land use, and wastewater effluent

remain unclear

• Fibers dominate in tributaries (71% of all particles)

– May be settling out in lakes

– Sources beyond WWTP effluent?

• Beads/pellets rare (1% of all particles)
