- •
Multiple methods were used to characterize the WEON in Lake Erhai sediment.
- •
Erhai sediment WEON comprised predominantly high molecular weight WEON species.
- •
Abundant humic substances aliphatic compounds, stable to biodegradation.
- •
PIII + V,n/PI + II + IV,n was taken as an indicator for WEON content in Erhai sediments.
- •
The composition and structure of the WEON affect the sediment properties.
