文摘
- •
The concentration, composition, bioavailability, and NDMA FP of PON and DON in wastewater effluents are compared.
- •
PON is enriched in protein and nucleic acids.
- •
PON is more bioavailable and shows higher NDMA yields compared to DON.
- •
PON contributes12–42% of total bioavailable org-N and 22–38% of total NDMA precursors.
- •
Awareness of possible adverse effects of PON on wastewater discharge and reuse applications is critical.
