The concentrations below LOD were imputed at LOD/.
Other analytes measured with all results below the LOD were α-, β-, γ-HBCD, in which α-, β-, γ-HBCD which was measured in carpet installation, electronic scrap, and gymnastic workers.
The abbreviations in the Multiple Comparisons of Industries are: Carpet Installation (CI), Chemical Manufacturing (CM), Electronic Scrap (ES), Foam Manufacturing (FM), Gymnastics (G), Nail Salon (NS), Rigid Board Installation (RB), Roofing (R), and Spray Polyurethane (SP). If the means of log-concentrations for two industries were significantly different, the comparison of the two industries would be presented in the table. For example, “CM-ES” means that the mean of log-concentrations for chemical manufacturing was significantly different from electronic scrap.
Samples above LOD were less than 50%.
