Abstract
insight on microplastics. In this technique, the decomposition of polymeric material in an inert environment (pyrolysis) followed by the size and polarity based separation by gas chromatography (GC) was performed. Finally, the fragment by mass spectrometric (MS) detector at the outlet of GC was analysed. In comparison of the MS data throughout the chromatogram with that of a known reference library, the specific polymer of the plastic material is analysed. This method is very efficient to gather information on polymer types and additives and also finds its usefulness towards the comparison of polymer resulting from fresh water and marine water systems. The understanding of structural and functional groups, surface morphology with elemental composition and the stability of the polymeric microparticles based on instrumental techniques such as FTIR, SEM with EDAX and TGA deemed quite satisfactory. The present research is contributed for the identification of plastic microparticles in the marine water and sand samples procured from the natural urban beach called Marina which is located in the Chennai City of South India. The hazard classification based on Globally Harmonized System (GHS) revealed the presence of various pyrolyzates under Irritant, Health Hazard and STOT (Specific Target Organ Toxicity) categories.
