Correction to Measuring Personal Exposure to Organophosphate Flame Retardants using Silicone Wristbands and Hand Wipes Stephanie C. Hammel, Kate Hoffman, Thomas F. Webster, Kim A. Anderson, and Heather M. Stapleton* Environ. Sci. Technol. 2016, 50 (8), 4483−4491; DOI:10.1021/acs.est.6b00030 The urine concentrations reported in the original paper1 were raw values but mistakenly reported as specific gravity-corrected. These do not change the overall results of the paper as the associations among specific gravity-corrected urine concentrations are very similar to those among the raw values. Page 4486, Section, Statistical Analysis. The last sentence should read, “Analysis results using each set of urine concentrations were essentially not differentiable, and the associations and graphs with raw urine concentrations are presented here.” Page 4487, Section, Specific-Gravity Corrected Urine. This section heading should be labeled, “Urine.” Page 4487, Table 2. The values in this table are correct; however, the section heading under “matrix and compound” should be “Raw Urine” rather than “SG-Corrected Urine.” Page 4488, Table 3 caption. The values in this table are correct, but the caption should read “Spearman Correlation Coefficients for PFR and PFR Metabolite Levels Measured in Paired Wristbands (n = 40), Hand Wipes (n = 38), and Urine (n = 40).” Page 4488, Figure 2. The values within this figure are correct, but the headings should exclude “sg” prior to BDCIPP and BCIPHIPP. Page 4488, Section, Comparing Wristbands and Hand Wipes to Urine. In the first paragraph, it should read, “TPHP and mono-ITP concentrations on the wristbands were not correlated with DPHP, but TPHP concentrations on the wristbands were correlated to specific-gravity-corrected DPHP concentrations.” Page 4489, Table 4 caption and headings. Again, the values in this table are correct for the raw urine concentrations. Therefore, the caption should read, “Results of Regression Analyses for Associations with Raw Urinary Metabolites Based on Parent Compounds on Wristbands and Hand Wipes Categorized as Tertiles.” The headings within the table should exclude “SG-corrected” before each of the PFR metabolitesBDCIPP, BCIPHIPP, and DPHP. Page 4489, Table 5 headings. The regression analyses utilized raw urine concentrations as the outcome; therefore, the headings should exclude “SG-corrected” before each of the metabolites.
