Inherent mineralization of 2,6-dichlorobenzamide (BAM) in unsaturated zone and aquifers - Effect of initial concentrations and adaptation

► BAM mineralized in BAM-contaminated aerobic aquifer sediments. ► In subsurface, fastest BAM mineralization in pre-exposed sandy sediments. ► Increased mineralization (adaptation) only observed in contaminated sandy sediment. ► In pristine sediments mineralization ratio increased with decreasing concentrations.
