红树林环境已被公认为海洋垃圾的陷阱。但目前尚不清楚红树林沉积物是否因沉积活跃而比其他海洋沉积物更有效地沉降微塑料。此外，红树林沉积物中的微塑料档案可以提供有关人类活动对整个历史环境污染影响的定量数据。微塑料丰度在高和低人类活动之间变化显著。红树林和邻近的泥滩沉积物作为微塑料螯合物，尽管具有相似的微塑料丰度和深度剖面。在20世纪50年代初印度尼西亚首次制造塑料的沉积层之前，观察到微塑料的减少趋势，但微塑料仍然存在于这些层之下，表明了向下的运动。这一发现突出了红树林沉积物作为微塑料汇的重要性。需要更多的研究来了解沉积物中微塑料沉积的机制，以及它们对红树林沉积物居民的命运和潜在影响。
Mangrove environments have been well recognized as marine litter traps. However, it is unclear whether mangrove sediments sink microplastics more effectively than other marine sediments due to active sedimentation. Furthermore, microplastics archives in mangrove sediments may provide quantitative data on the impact of human activities on environmental pollution throughout history. Microplastic abundance varied markedly between high and low anthropogenic activities. Both mangrove and adjacent mudflats sediments act as microplastic sequesters, despite having similar microplastic abundances and depth profiles. The decreasing trend of microplastics was observed until the sediment layers dated to the first-time plastic was manufactured in Indonesia, in the early 1950s, but microplastics remained present beneath those layers, indicating the downward movements. This discovery highlighted the significance of mangrove sediments as microplastic sinks. More research is needed to understand the mechanisms of microplastic deposition in sediments, as well as their fate and potential impact on mangrove sediment dwellers.
