AB  - Standard reference materials (SRMs) have been commonly used to perform quality 
      assurance and quality control (QA/QC) in soil total metal concentration analyses 
      or bioaccessibility assessment. In this study, 10 experimenters from 4 
      laboratories determined bioaccessibility of lead (Pb) in 4 widely-used SRMs (NIST 
      2710a, NIST 2587, BGS 102, and GBW 07405). Based on the gastric phase (GP) of the 
      unified BARGE bioaccessibility method (UBM) and the Solubility Bioavailability 
      Research Consortium procedure (SBRC), Pb bioaccessibility in SRMs was compared 
      within and between laboratories to assess their intra-laboratory repeatability 
      and inter-laboratory reproducibility. Lead bioaccessibility was 
      14.1 +/- 2.44%-101 +/- 2.48% in the 4 SRMs. The values were in vivo validated based 
      on a mouse model in previous studies (R(2) = 0.97-0.98), suggesting the 
      reliability of Pb bioaccessibility data. Strong correlations were observed for Pb 
      bioaccessibility among 7 experimenters (R(2) = 0.94-0.99) at the Nanjing 
      University (NJU) laboratory and similar strong correlations were also found 
      between each two of the 4 laboratories (R(2) = 0.94-0.98), illustrating 
      consistency in intra- and inter-laboratory performance. The intra-laboratory 
      repeatability and inter-laboratory reproducibility were generally acceptable with 
      relative standard deviations (RSDs) of Pb bioaccessibility being </=10% within 
      laboratory and </=20% between laboratories, except in a soil with low bioaccessible 
      Pb (BSG 102). Our study suggested that measurements of Pb bioaccessibility in 
      SRMs based on the two in vivo validated methods were repeatable and reproducible 
      within and between laboratories, further verified their reliability being used as 
      QA/QC samples during Pb bioaccessibility assessment.
