Key Findings
- 01All tested nanoplastics contained detectable levels of metals and metalloids, varying in concentration and type depending on the original plastic product.
- 02Specific elemental ratios (e.g., Ti/Fe, Cr/Fe, Si/Al) differed significantly between nanoplastics from different plastic types and natural soil particles, allowing for source differentiation.
- 03Nanoplastics derived from aged ocean plastic fragments showed elemental ratios intermediate between new plastics and natural soil, suggesting a combined influence of manufacturing additives and environmental weathering.
