Simultaneous
Trace Identification and Quantification
of Common Types of Microplastics in Environmental Samples by Pyrolysis-Gas
Chromatography–Mass Spectrometry
Posted on 2017-04-09 - 00:00
The content of microplastics (MP)
in the environment is constantly
growing. Since the environmental relevance, particularly bioavailability,
rises with decreasing particle size, the knowledge of the MP proportion
in habitats and organisms is of gaining importance. The reliable recognition
of MP particles is limited and underlies substantial uncertainties.
Therefore spectroscopic methods are necessary to ensure the plastic
nature of isolated particles, determine the polymer type and obtain
particle count related quantitative data. In this study Curie-Point
pyrolysis-gas chromatography–mass spectrometry combined with
thermochemolysis is shown to be an excellent analytical tool to simultaneously
identify and optionally quantify MP in environmental samples on a
polymer specific mass related trace level. The method is independent
of any mechanical preselection or particle appearance. For this purpose
polymer characteristic pyrolysis products and their indicative fragment
ions were used to analyze eight common types of plastics. Further
aspects of calibration, recoveries, and potential matrix effects are
discussed. The method is exemplarily applied on selected fish samples
after an enzymatic-chemically pretreatment. This new approach with
mass-related results is complementary to established FT-IR and Raman
methods providing particle counts of individual polymer particles.
