The dataset consists of compilations of measured and calculated physicochemical property values for PCBs, PBDEs, PCDDs and PAHs. The properties included in this dataset are the octanol-water partition coefficient, melting point, vapor pressure and water solubility. The measured property values were obtained from a critical review of the scientific literature. The calculated values were obtained using the following applications: ACD/Percepta, ChemAxon Plugin Calculators, EPI Suite, NICEATM, Online Chemical Modeling Environment (OCHEM), OPERA, SPARC, and Toxicity Estimation Software Tool (T.E.S.T.). This dataset is associated with the following publication: Stevens, C., J. Patel, M. Koopmans, J. Olmstead, S. Hilal, N. Pope, E. Weber, and K. Wolfe. Demonstration of a consensus approach for the calculation of physicochemical properties required for environmental fate assessments. CHEMOSPHERE. Elsevier Science Ltd, New York, NY, USA, 194: 94-106, (2018).

These data were collected as part of a study that used a sediment fingerprinting model to better understand sources of PCB-contaminated suspended sediments within stormflow in the Back River watershed. This metadata record contains 4 tables of data used to model and assess the source of storm sediment collected within the Back River watershed in Maryland in 2023. Included in the dataset are analytical results from sediment samples collected from the landscape, in stream banks, during storms using passive samplers, and intact cores, and analyzed for (1) PCB, (2) elemental metals and carbon content, and (3) grain size. Also included are calculated PCB concentrations in porewater using sediment concentration from storm and core samples.

This metadata record contains 6 tables used to assess sources of Polychlorinated Biphenyls (PCB) in the Back River watershed, Baltimore City, Maryland. Included in the dataset are PCB concentrations of surface water and porewater passive samplers from Herring Run, Moores Run, tidal Back River, and Back River Wastewater Treatment Plant; PCB concentrations of bed sediments and other solids, Fat, Oil, and Grease (FOG) samples, and road sediments; dissolved organic carbon (DOC), total suspended solids (TSS), and particulate organic carbon (POC) concentrations of grab samples; and PCB concentrations of passive samplers from pump stations collected in 2018-2020.

Two types of passive samplers for polychlorinated biphenyl (PCB) analysis were deployed in the Clinton River Area of Concern in 2019: semipermeable membrane devices for water and in-stream sediment samplers. Samplers were deployed in July 2019 and retrieved in August 2019. Additionally, bank sediment samples for PCB analysis were collected by the U.S. Geological Survey (USGS) in August 2019 and catch basin bottom material samples for PCB analysis were collected by LimnoTech in November 2019 under contract with the U.S. Army Corps of Engineers. These data are a part of a larger study and associated USGS report (https://doi.org/10.3133/sir20235030).
