Figure 1. Median concentrations of PFR metabolites displayed per country (ng/mL, SG-corrected). Metabolites detected in more than 50% of urine samples across all 5 countries are shown, with the parent compound in brackets. The y-axis is shown on a logarithmic scale. The box represents the median and IQR, with the whiskers representing the 5th and 95th percentiles. Data points outside the 5%-95% range are plotted as individual points. Metabolite concentrations arranged per metabolite rather than per country to show differences across countries for each metabolite are displayed in Figure 2. PFR: Organophosphate flame retardant; SG: specific gravity; IQR: interquartile range; DPHP: diphenyl phosphate; TPHP: triphenyl phosphate; BDCIPP: bis (1,3-dichloro-2-propyl) phosphate; TDCIPP: tris (1,3-dichloro-2-propyl) phosphate; BCIPHIPP: 1-hydroxy-2-propyl bis (1-chloro-2-propyl) phosphate; TCIPP: tris (1-chloro-2-propyl) phosphate; EHPHP: 2-ethylhexyl phenyl phosphate; EHDPHP: 2-ethylhexyldiphenyl phosphate; 5-HO-EHDPHP: 2-ethyl-5-hydroxyhexyl diphenyl phosphate.
