Dataset containing concentrations of stormwater-driven substances in three urban streams under dry and wet weather conditions and in bottom sediments in Sweden

This dataset presents the concentrations of a wide range of substances in three urban streams in Sweden. Data set involves concentrations in stream water collected under dry and wet weather conditions on several occasions as well as a one-time collection of bottom sediment. The collected data included 34 targeted PFAS compounds in water and 35 targeted PFAS in sediment as well as 30 precursors analyzed by total oxidizable precursors assay (TOP-Assay).
For detailed information about the sampling sites and sampling occasions, please refer to "Data_description.pdf."
The file "PFAS_in_water_34_targeted_PFAS.xlsx" contains PFAS concentrations measured in urban streams under dry and wet weather conditions. The file "PFAS_in_sediment_35_targeted_PFAS.xlsx" contains PFAS concentrations in the bottom sediment. The file "PFAS_in_sediment_30PFAS_TOP_Assay.xlsx" includes concentrations of 30 precursor compounds in bottom sediment, analyzed using the TOP Assay method. Units for the data are ng/L for measurements for water and μg/kg dry weight for sediment. All files are also available in CSV format with the same filenames.
