Schaper, Jonas L. published the artcileFate of Trace Organic Compounds in the Hyporheic Zone: Influence of Retardation, the Benthic Biolayer, and Organic Carbon, Recommanded Product: Diatrizoic Acid, the main research area is trace organic compound fate hyporheic zone lowland river Germany.
The fate of 28 trace organic compounds (TrOC) in the hyporheic zone (HZ) of an urban lowland river in Berlin, Germany, was assessed. Water was were collected hourly over 17-h from the river and at three HZ depths using mini-point samplers. Four relatively variable time series were subsequently used to calculate first-order removal rates and retardation coefficients with a one-dimensional reactive transport model. Reversible sorption processes led to substantial retardation of many TrOC along the studied hyporheic flow path. Some TrOC (e.g., dihydroxy-carbamazepine, O-desmethylvenlafaxine, venlafaxine) were stable in the HZ; others were readily removed with half-lives in the first 10-cm of the HZ of 0.1 ± 0.01 h (iopromide) to 3.3 ± 0.3 h (tetramadol). Others were readily removed with half-lives in the first 10-cm of the HZ from 0.1 ± 0.01 h for iopromide to 3.3 ± 0.3 h for tramadol. Removal rate constants of the majority of reactive TrOC were highest in the first 10-cm of the HZ, where removal of biodegradable dissolved organic matter was also highest. Since conditions were oxic along the top 30-cm of the studied flow path, the authors attributed this finding to high microbial activity typically associated with the shallow HZ. Hence frequent, short vertical hyporheic exchange flows could be more important for reach-scale TrOC removal than long, lateral hyporheic flow paths.
