Phase-specific behavior of PAHs and OPAHs across the sediment-water continuum in a nutrient-enriched agricultural river.
Agricultural rivers receive nutrients together with polycyclic aromatic hydrocarbons (PAHs) and oxygenated PAHs (OPAHs), yet whether their nitrogen-associated behavior differs across the sediment-water continuum remains unclear. Using paired surface-water and sediment samples from the Zhangshi River, China, we compared...
