Remobilized metals threaten urban wetlands | Science
Urban wetland restoration is gaining international momentum (1, 2). This strategy alleviates biodiversity loss by providing pivotal habitats for local wildlife and migratory birds in urban areas (1). Although urban wetland restoration provides substantial ecological benefits, these projects may inadvertently remobilize legacy metal contaminants (LMCs), including harmful chemicals such as mercury, that were produced by anthropogenic activities and have since accumulated in urban soils and sediments. Project planners must work to prevent or mitigate the damage that LMCs could cause.
