Polymer information for MPs detected in this study.
| Polymer Type | Monomer | Density (g/cm3) | Main Application | Fraction |
|---|---|---|---|---|
| PP | Propylene | 0.85–0.94 | Agricultural film, bottle, food packaging etc. | 1 |
| PA6 | Caprolactam | 1.13 | Bearings, automotive applications, etc. | 50 |
| PET | Terephthalic acid and ethylene glycol | 1.33–1.38 | Food and drug packaging film, packaging bottle, automobile application, etc. | - |
| PVC | Vinyl chloride | 1.41 | Pipe, cable insulation, etc. | 10,551 |
PET lacks ecological toxicity data, therefore its hazard score cannot be determined. The value for the score of each polymer is taken from Lithner [24].
