Climate change and plastics pollution are dual threats to marine environments. Here we use biogeochemical and microplastic modelling to show that even if there is complete removal of microplastics and cessation of deposition in the oceans in 2022, regional recovery from microplastic-induced remineralization and water column deoxygenation could take hundreds of years for coastal upwelling zones, the North Pacific and Southern Ocean. Surface stratification and reduced sea ice cover further impede regional recovery, highlighting the importance of aggressive mitigation of plastic pollution.

从微塑料引起的海洋脱氧中恢复可能需要几个世纪

气候变化和塑料污染是对海洋环境的双重威胁。在这里，我们使用生物地球化学和微塑料模型来表明，即使到 2022 年完全清除微塑料并停止在海洋中沉积，对于沿海上升流区来说，微塑料引起的再矿化和水柱脱氧的区域恢复可能需要数百年的时间，北太平洋和南大洋。地表分层和海冰覆盖面积减少进一步阻碍了区域恢复，凸显了积极缓解塑料污染的重要性。
