Plastic pollution in natural water bodies is an emerging problem that requires quick actions. Recently, the role of micro- and nanoplastics in pollution and health issues has been realized and taken seriously. In this paper, we have studied optical properties, such as NIR spectra and refractive index, of some common plastic materials and present a method and data to screen especially problematic transparent plastics with rough surface in aquatic environments. We also give an outlook of possible optical measurement methods that could be used for detection of micro- and nanoplastics.
自然水体中的塑料污染是一个亟待解决的新兴问题。最近，人们已经意识到微塑料和纳米塑料在污染和健康问题方面的作用，并开始认真对待。本文研究了一些常见塑料材料的光学性质，如近红外光谱和折射率，并提出了一种方法和数据，用于筛选水环境污染中具有粗糙表面的特别有问题的透明塑料。我们还展望了可能用于检测微塑料和纳米塑料的光学测量方法。
