Figure 2.

Figure 2A is a set of eight tree maps titled active concentration at 50 percent- uppercase l, Expo uppercase l, point-of-departure uppercase l, regulatory oral noncancer reference doses uppercase l, active concentration at 50 percent- uppercase h, Expo uppercase h, point-of-departure uppercase h, and regulatory oral noncancer reference doses uppercase h plotting chemical proportions contained in each of the designed mixtures for inorganic substances, other industrial chemicals, polycyclic aromatic hydrocarbons, pesticides, and phthalates. Figure 2B is a horizontal bar graph plotting active concentration at 50 percent- uppercase l, active concentration at 50 percent- uppercase h, Expo uppercase l, Expo uppercase h, point-of-departure uppercase l, point-of-departure uppercase h, regulatory oral noncancer reference doses uppercase l, and regulatory oral noncancer reference doses uppercase l (y-axis) across effective concentration at 10 percent (Total concentration in microMolar), ranging from 10 begin superscript 1 end superscript to 10 begin superscript 4 end superscript in unit increments (x-axis).

Summary of the properties of the designed mixtures used in this study. (A) Treemap of the chemical proportions contained in each of the designed mixtures. The color represents the classes of environmental contaminants that were selected in the study. (B) Cumulative (maximum) concentration of the chemicals in each designed mixture. See acronym explanations and description of the designed mixtures in Table 1.
