Mitigating Microplastics Pollution in Urban Water Systems : Flow, actors, and control measures
Abstract
Water pollution has long been considered a challenge in urban areas.Urban wastewater and stormwater act as transport pathways for pollutants from urban areas to receiving waters.Microplastics are a pollution problem of growing concern.As part of the zero-pollution action plan for 2050, the European Commission has set the target to reduce emissions of microplastics to the environment by 30% from 2016 to 2030.The majority of the microplastics originate from sources on land, and urban areas are viewed as particular hotspots.More knowledge is needed on the sources and pathways of microplastics within the urban area, such as to and from urban water systems.To be able to reduce microplastics pollution, there is also a need to understand where control measures can be introduced and make an impact in terms of reduced loads to the environment.For control measures to be implemented, there is also a need to understand the incentives and challenges that the actors, who have a responsibility related to the flows, encounter when working with pollution control.
