Abstract

Microplastics (MPs) are emerging pollutants in our environment. However, their identification under real environmental conditions remains challenging, particularly in the case of MPs found in water sources, where other organic materials, such as algae, are present. Custom-prepared MPs (PET, PS, PLA) - commonly found in the aquatic environment – were tested in the dry state, in the water colloidal solutions, and/or in the presence of algae Chlorella sp. A multi-method approach, comparing different biophotonic methods, including FTIR, Raman (conventional or Surface Enhanced Raman Spectroscopy (SERS)) and spectrally-resolved confocal fluorescence microscopy methods were employed. We tested the capabilities of the applied methods to detect the presence of MPs in complex environmental conditions and thus the possibilities for their use for an in-situ effective monitoring.

通过生物光子学方法的比较，鉴定水生环境中或存在小球藻的微塑料

微塑料（MPs）是我们环境中的新兴污染物。然而，在真实环境条件下对它们的识别仍然具有挑战性，特别是在水源中发现的MPs，其中存在其他有机物质，如藻类。定制制备的MPs (PET， PS， PLA) -通常存在于水生环境中-在干燥状态，水胶体溶液和/或小球藻存在下进行测试。采用多方法方法，比较不同的生物光子方法，包括FTIR，拉曼（传统或表面增强拉曼光谱（SERS））和光谱分辨共聚焦荧光显微镜方法。我们测试了应用方法在复杂环境条件下检测MPs存在的能力，从而测试了将其用于现场有效监测的可能性。

期刊介绍： Polymer Testing focuses on the testing, analysis and characterization of polymer materials, including both synthetic and natural or biobased polymers. Novel testing methods and the testing of novel polymeric materials in bulk, solution and dispersion is covered. In addition, we welcome the submission of the testing of polymeric materials for a wide range of applications and industrial products as well as nanoscale characterization. The scope includes but is not limited to the following main topics: Novel testing methods and Chemical analysis • mechanical, thermal, electrical, chemical, imaging, spectroscopy, scattering and rheology Physical properties and behaviour of novel polymer systems • nanoscale properties, morphology, transport properties Degradation and recycling of polymeric materials when combined with novel testing or characterization methods • degradation, biodegradation, ageing and fire retardancy Modelling and Simulation work will be only considered when it is linked to new or previously published experimental results.
