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

Contaminant concentrations in the water phase were measured during both dry and wet weather conditions in three Swedish urban streams: Fyrisån in Uppsala, Ljurabäck in Norrköping, and Storån in Söderköping. Sediment samples were also collected from these three streams, along with an additional stream: Kättstabäcken, a stream near Stockholm Arlanda Airport that receives stormwater discharges through a pond system.The collected data included 34 targeted PFAS, 13 phthalates, 10 organotin compounds (OTCs), 16 polycyclic aromatic hydrocarbons (PAHs), and 9 phenols (i.e., nonylphenols, octylphenols and -ethoxylates) in water phase.

Bottom sediment data included analysis results for 35 targeted PFAS as well as 30 PFAS precursors (by using TOP assay), 13 phthalates, 10 OTCs, 16 PAHs, and 8 phenols (excluding BPA). For detailed information about the sampling sites and sampling occasions, please refer to "Data_description_v3.pdf"
