| description | A reference exposure matrix representing MNP contamination in processed packaged meats — sausages, cold cuts, bacon, and similar products. High nano-particle content from mechanical processing (grinding, emulsification introduces fragments) and packaging materials (plastic wrap shedding PE/PS nanofragments, PVDC coatings). Skewed toward ultrafine and fine_nano fractions due to contamination from processing equipment and cling-film packaging. |

| geographic_region | Europe (general) |
| notes | Demonstration matrix for nano-heavy dietary exposure via processed meats. Not empirically validated — composition reflects known contamination pathways from processing and packaging. |
