Correction to Mutagenic Azo Dyes, Rather than Flame Retardants, are the Predominant Brominated Compounds in House Dust Hui Peng, David M.V. Saunders, Jianxian Sun,* Paul D. Jones, Chris K. C. Wong, Hongling Liu, and John P. Giesy* Environ. Sci. Technol. 2016, 50, 12669−12677; DOI:10.1021/acs.est.6b03954. In Table 1 (page 12 673) of the published paper, the information should be replaced with correct compound Table 1. m/z values, retention times and predicted formulas of the 10 most-abundant brominated compounds in house dust identified by DIPIC-Frag m/z 532.0719 478.9585 478.0603 478.9592 482.5869 532.0694 715.2162 715.2162 458.0694 500.0808

formulas and monoisotopic m/z values, whereas this information was correctly shown in the supporting informationa. For example, the m/z for the first compound ([M+1]) should be replaced by 532.0719 [M]. A corrected Table 1 is included above. In addition, the compound formula of the first compound could not be exclusively determined between C23H23BrN3O7 and C21H21BrN6O6 with similar m/z values and potential fragments, and C21H21BrN6O6 should be the formula of the first compound, as validated by chemical standard (Disperse Blue 373). Accordantly, the compound formula of Figure 3D should be corrected from C20H18BrN3O7 to C18H16BrN6O6, and from C23H23BrN3O7 to C21H21BrN6O6.
