Data set resulting from a targeted literature review of PCB concentrations in environmental media, as well as of total PCB dietary intake. Table S1 shows all studies that underwent full-text review (Figure 1). Table S2 shows all included studies and resulting PCB exposure estimates (used to generate Figures 2-4). Table S3 provides the data and analysis used to examine the effect of congener number on diet studies.
