From: A round robin approach to the analysis of bisphenol a (BPA) in human blood samples

Figure 6

Analysis of uBPA and BPA-G in environmental samples. uBPA concentrations were analyzed in five environmental serum samples in Phase 2 (A) and six environmental serum samples in Phase 3 (B). BPA-G concentrations were analyzed for the same five environmental serum samples in Phase 2 (C) and six environmental serum samples in Phase 3 (D). Sample 5 in Phase 2 had high concentrations of BPA-G reported by all four laboratories, requiring this data to be presented with a different scale. See inset for better resolution of Samples 1–4. In all panels, graphs represent mean ± standard deviations reported from each laboratory.
