Dataset containing concentrations of stormwater-driven substances in 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 urban streams 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).
