Plastics are a ubiquitous pollutant, and are rapidly colonized by biofilms that sorb inorganic and organic components, forming the interface between plastics and the environment. This study provides a proof of concept for the use of automated quantitative mineralogy (AQM) to illuminate and analyse the metal and mineral component of the plastisphere on plastics sampled from temperate and tropical aquatic localities. The method is non-destructive and requires minimal sample preparation, providing a 2-dimensional visualisation and semi-quantitative analysis of the arrangement of biogenic and abiogenic components, highlighting potential interactions between these components. Our results also communicate the potential role of plastic structure on mineral retention in relation to environmental parameters that can influence mechanical degradation. AQM provides a novel avenue to understand the minerals associated with plastics, and increases our knowledge of the interfacial composition, which can inform potential interactions, transformations and insights into the long-term fate of plastic pollutants.

自动定量矿物学和塑料 – 水生环境中塑料表面的新视角
塑料是一种无处不在的污染物,并迅速被生物膜定植,这些生物膜吸附无机和有机成分,形成塑料与环境之间的界面。这项研究为使用自动定量矿物学 (AQM) 来阐明和分析从温带和热带水生地区采样的塑料上塑料球的金属和矿物成分提供了概念验证。该方法是非破坏性的,只需最少的样品制备,提供生物和非生物成分排列的二维可视化和半定量分析,突出这些成分之间的潜在相互作用。我们的结果还传达了塑料结构对矿物保留的潜在作用,与可能影响机械降解的环境参数有关。AQM 为了解与塑料相关的矿物提供了一条新的途径,并增加了我们对界面成分的了解,这可以为潜在的相互作用、转化和对塑料污染物长期命运的见解提供信息。
