Quternary ammonium compounds in floodplain soils of the Lahn river (Hesse, Germany)

This dataset contains all raw data from the investigation of quaternary ammonium compound (QAC) concentrations in floodplain soils of the river Lahn (Hesse, Germany). This includes (1) the QAC concentrations and element contents (C, N, H, S) for each 2 cm depth segment, (2) averaged QAC concentrations over 10-25 cm segments and (3) sedimentation rates. Information on the sampling sites can be found in Weber et al. (2022): https://doi.org/10.1016/j.scitotenv.2021.152039.
