Simultaneous attenuation of trace organics and change in organic matter composition in the hyporheic zone of urban streams

Abstract Trace organic compounds (TrOCs) enter rivers with discharge of treated wastewater. These effluents can contain high loads of dissolved organic matter (DOM). In a 48 h field study, we investigated changes in molecular composition of seven DOM compound classes (FTICR-MS) and attenuation of 17...
