This file presents physicochemical properties of soils, house dusts, PCBs, and the bioaccessibility values calculated from the analysis of PCBs in the soils, house dusts, and synthetic digestive fluids. Bioaccessibility values were calculated using the ratio of the analyte in the sediment relative to that in the digestive fluids. The first tab in the excel spreadsheet is the data dictionary and contains the meta data (column headings and fields). The second tab contains the soil/dust/PCB physicochemical properties and the associated bioaccessibility values. This dataset is associated with the following publication: Shen, H., W. Li, S. Graham, and J. Starr. The role of soil and house dust physicochemical properties in determining the post ingestion bioaccessibility of sorbed polychlorinated biphenyls. CHEMOSPHERE. Elsevier Science Ltd, New York, NY, USA, 217: 1-8, (2019).
