Macro and Microplastics in Stormwater and Combined Sewer Overflows in Paris Megacity
AI summary Read the abstract
Researchers measured macro and microplastic concentrations in stormwater runoff and combined sewer overflows in Paris, finding that these urban drainage systems are a significant and underestimated pathway for plastic pollution to enter rivers and ultimately the ocean.
Stormwater and combined sewer overflows (CSO) might represent an important source of macro and microplastics in the environment, but such fluxes are poorly investigated. In order to fill this knowledge gap, macro and microplastic concentrations were investigated (i)...

Macro and microplastics in stormwater and combined sewer overflows in Paris megacity
AI summary Read the abstract
This French study quantified macro and microplastics in stormwater and combined sewer overflows in the Paris metropolitan area, identifying these urban discharge events as significant pathways for plastic pollution to reach aquatic environments. The results highlight the role of urban infrastructure and rainfall events in transporting plastic debris from cities to waterways.
Sourcing, Timing, and Extent of Microplastic Mobilization by Urban Flooding
AI summary Read the abstract
Researchers studied how urban flood events mobilize microplastics stored in urban watersheds, finding that storm flooding dramatically increases the transport of accumulated plastic particles into waterways and downstream environments. As climate change intensifies urban flooding frequency, understanding microplastic mobilization dynamics is critical for predicting pollution loading into aquatic ecosystems and designing stormwater management systems that reduce plastic discharge.

First assessement of sources and fate of macro and micro plastics in urban hydrosystems : Case of Paris megacity
AI summary Read the abstract
This PhD thesis presents the first comprehensive assessment of macro and microplastic sources and transport pathways in the urban hydrosystem of the Paris megacity. Researchers found that stormwater and combined sewer overflows are major pathways delivering plastic from urban surfaces to the Seine River and ultimately to the ocean.
Microplastic Contamination of Sediment and Water Column in the Seine River Estuary
AI summary Read the abstract
Microplastic contamination is documented throughout the Seine River estuary in both water and sediments, with particle concentrations varying by tidal cycle and proximity to urban discharge points. Estuaries act as transitional accumulation zones where riverine microplastics concentrate before entering the marine environment, amplifying exposure for estuary-dwelling species.
