Thermal desorption and extraction coupled with gas chromatography and mass spectrometry for the quantification of polystyrene nanoplastic in pak choi
Summary
This study developed a thermal desorption and extraction method coupled with gas chromatography–mass spectrometry to identify and quantify plastic additives and polymer-associated chemicals in environmental samples. The approach enables sensitive detection of plastic-derived contaminants in complex matrices.
Rationale It has been demonstrated that micro- and nanoplastics (MNPs) can be found in soil, and that MNPs can be taken up by plants. In order to conduct a risk assessment for human consumption, it is necessary to have an estimate of the mass concentr
