Transmission Electron Microscopy

The presence of small plastic particles in the environment, reported for the first time in the 1970's, has only recently been recognized as a global issue. Although environmental awareness continues to grow, so does its consumption and associated risks. The number of studies reporting the presence of microplastics, has grown exponentially as did the concern over plastic degradation into smaller particles like nanoplastics, a potentially more pernicious form of plastic pollution.

Nanoplastic is an emerging topic of relevance in environmental science. The analytical methods for microplastic have a particle size limit of a few micrometers so that new methods have to be developed to cover the nanometer range. This contribution reviews the progress in environmental nanoplastic analysis and critically evaluates which techniques from nanomaterial analysis may potentially be adapted to close the methodological gap. A roadmap is brought forward for the whole analytical process from sample treatment to particle characterization.
