Globally, the coastal lagoons of Lagos (Nigeria), Sakumo (Ghana) and Bizerte (Tunisia)—close to large urban centers and without waste and sewage treatment systems—are among the water ecosystems most affected by microplastic pollution. However, the highest concentrations of microplastics have been detected in Barnes Sound and other small lagoons in a protected area in the north of Florida Bay (U.S.), a particular case that can be explained by the transport of microplastics carried by hurricanes from polluted areas.
