Differential kinetics and temperature dependence of abiotic and biotic processes controlling the environmental fate of TNT in simulated marine systems

► Biotic/abiotic removal kinetics of TNT was differently affected by temperature. ► Temperature sensitivity of sediment PBC for TNT linked to diffusion processes. ► Sediment sorption affinity for TNT not impacted by temperature. ► Higher TNT accumulation expected in sediments with decreasing temperature.
