TI  - Multi-Analytical Approach to Characterize the Degradation of Different Types of 
      Microplastics: Identification and Quantification of Released Organic Compounds.

AB  - Microplastics and nanoplastics represent one of the major environmental issues 
      nowadays due to their ubiquitous presence on Earth, and their high potential 
      danger for living systems, ecosystems, and human life. The formation of both 
      microplastics and nanoplastics strongly depends on both the type of pristine 
      materials and the degradation processes related to biological and/or abiotic 
      conditions. The aim of this study is to investigate the effect of two of the most 
      relevant abiotic parameters, namely temperature and light, taken under direct 
      control by using a Solar box, on five types of reference polymers: high density 
      polyethylene (HDPE), low density polyethylene (LDPE), polypropylene (PP), 
      polystyrene (PS), and polyethylene terephthalate (PET). A multi-analytical 
      approach was adopted to investigate in detail the first steps of plastics 
      degradation. Samples of plastic materials at different degradation times were 
      analyzed by means of (1)H NMR spectroscopy and thermal desorption gas 
      chromatography mass spectrometry (TD-GC-MS) technique. Several minor molecular 
      species released during degradation were consistently identified by both 
      techniques thus providing a comprehensive view of the various degradation 
      products of these five types of microplastics.
