A critical synthesis of seagrass meadows as microplastic sinks: Current trends and research gaps
This systematic review of 84 studies finds that seagrass meadows act as natural traps for microplastics, accumulating higher concentrations in their sediments than surrounding areas. While this filtering role may protect open waters, it also means these important coastal ecosystems are bearing a disproportionate burden of plastic pollution.
Factors influencing microplastic abundances in the sediments of a seagrass-dominated tropical atoll
Researchers investigated factors controlling microplastic abundance in sediments of a seagrass-dominated tropical atoll. They found that seagrass density, water flow patterns, and proximity to human settlements all influenced microplastic accumulation, with denser seagrass meadows trapping more particles in their sediments. The study raises concerns that microplastic buildup in seagrass ecosystems could threaten the ecological services these habitats provide, including carbon storage and biodiversity support.
A Review of Seagrass Bed Pollution
This review summarizes the major threats facing seagrass ecosystems worldwide, including pollution from microplastics, heavy metals, and nutrient runoff from human activities.
