Standard Test Method for Identification of Polymer Type and Quantity of Microplastic Particles and Fibers in Waters with High to Low Suspended Solids Using Pyrolysis-Gas Chromatography/Mass Spectrometry

Importancia y uso:

5.1 Preliminary studies have identified polymeric organic compounds as contaminants in treated drinking water, wastewater, surface water, ground water, and marine waters. These polymers may be harmful to the environment and adversely affect human health, and in these circumstances, mass estimation is commonly required. A universal, analytical method will help to normalize data from around the world and better understand which polymers are most frequently found in various climatic and geological locations (5-7). Pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) has many advantages in that both polymer identification and mass quantification can be easily accomplished by chromatographic separation in combination with mass spectral analysis.
