Source-to-sink geoscientific domain and environmental plastic cycle studies are two major scientific worlds starting to interact, taking benefit from each other. To advance in our understanding of the sharing benefits between interconnecting research communities, we firstly carry out a review from sedimentology, sources, sinks, transport dynamic and pathways of microplastics along the entire source-to-sink (S2S) profile. The main peculiarities for microplastics are the numerous and distributed sources across the environment, as well as the importance of physical properties and shape factors. Then, we propose a review of plastic mass concentration along the S2S profile to discuss influence of sedimentation rate on microplastic accumulation and to identify intermediate reservoir and final fates. Deep sea deposits, including turbidite systems are potentially hotspots for microplastic accumulation that are poorly studied, deserving much more attention to scale mass balance studies. This review finally highlights areas of synergies between S2S geoscientific and plastic communities to guide future interdisciplinary microplastic research. Most of these issues will rely on multiplying measurements across all matrices and environments based on standard technology to generate homogenized measurements and large database for plastic and microplastics.

人为标记的从源到汇的视角：对整个环境中微塑料浓度、途径和积累的首次评估


源到汇地球科学领域和环境塑料循环研究是两个主要的科学领域开始相互作用，互相受益。为了加深我们对相互联系的研究团体之间共享利益的理解，我们首先从沉积学、来源、汇、传输动态和微塑料沿整个源到汇（S2S）剖面的路径进行审查。微塑料的主要特点是环境中来源众多且分布广泛，以及物理特性和形状因素的重要性。然后，我们建议对沿 S2S 剖面的塑料质量浓度进行回顾，以讨论沉降速率对微塑料积累的影响，并确定中间储层和最终命运。深海沉积物，包括浊积岩系统，是微塑料积累的潜在热点，但研究很少，值得更多地关注尺度质量平衡研究。这篇综述最终强调了 S2S 地球科学和塑料界之间的协同作用领域，以指导未来的跨学科微塑料研究。这些问题中的大多数将依赖于基于标准技术对所有基质和环境进行乘法测量，以生成塑料和微塑料的均质测量结果和大型数据库。
