- •
PAHs mainly accumulated in deeper soils and were dominant in 3-ring PAHs.
- •
Low molecular weight PAHs in almost all soils exceeded the Threshold Effects Level.
- •
Urbanization led to higher toxicity of PAHs in soil compared to reclamation.
- •
SOM exhibited different relationships with PAHs in soil under five land uses.
- •
Large aggregates benefit high molecular weight PAHs accumulation in soil cores.
