Figure 4.

Figure 4 is a Bayesian curve titled iCell Neurons (Total Outgrowth) or active concentration at 50 percent uppercase h; effective concentration at 10 percent equals 0.29 [0.25 to 0.33] microMolar plotting Effect (Fraction of Vehicle), ranging from 0 to 1 in increments of 0.2 (y-axis) across Total concentration in microMolar, ranging from 1 to 10000 in increments of multiplication of 10 (x-axis). The curve depicts Bayesian curve-fitting examples of concentration–response profiles for individual chemicals (insets) and a representative designed mixture, namely, Benz (lowercase a) anthracene 137 [46 to 420], Naphthalene 108 [37 to 309], Fluoranthene 104 [42 to 259], lowercase p, p prime- uppercase d d t 5.5 [2.3 to 11.0], Dieldrin 6.2 [2.7 to 12.1], Aldrin 5.9 [2.1 to 9.6], Heptachlor 5.3 [2.5 to 8.4], Lindane 126 [39 to 367], Disulfoton 150 [36 to 413], Endrin 85 [27 to 307], Diazinon 64 [29 to 106], Heptochlor epoxide 15 [7.1 to 27], Pentachlorophenol 13 [8.3 to 21], Dibutyl phthalate 235 [87 to 505], Chlorpyrifos 5.1 [3.0 to 7.5], Di (2-ethylhexyl) phthalate 1.9 [0.42 to 3.9], 2;4;6-Trichlorophenol 61 [11 to 177], Ethion 45 [6.0 to 111], Azinphos-methyl 41 [6.2 to 90], 2,4,5-Trichlorophenol 3.6 [1.3 to 6.6], Parathion 118 [32 to 555], Benzo (lowercase b) fluoranthene 83 [27 to 234], Trifluralin 14 [5.8 to 34], Acenaphthene 207 [31 to 451], lowercase p, p prime- uppercase d d d 6.0 [2.8 to 12], Benzidine 116 [29 to 292], Endosulfan 5.2 [2.3 to 12], Methoxychlor 5.4 [2.8 to 11], 2;4-Dinotroluene 174 [51 to 504], Dicofol 5.4 [3.0 to 8.7], lowercase p cresol 204 [54 to 498], lowercase o, p prime- uppercase d d t 5.3 [3.0 to 8.4], 2-methyl-4,6-dinitrophenol 26 [10 to 58], 1;2;3-Trichlorobenzene 261 [70 to 660], Lead nitrate 60 [0.66 to 229], Cadmium Chloride 3.1 [2.1 to 4.6], Zinc chloride 94 [31 to 334], Mercuric chloride 0.02 [0.01 to 0.05], Potassium chromate (uppercase v i) 2.6 [1.5 to 4.8], Cobalt chloride 42 [10.7 to 85], and Nickel chloride 3.4 [2.3 to 4.9] by plotting Effect (Fraction of Vehicle; y-axis) across Total concentration in microMolar, ranging between 0.01 to 100 (x-axis).

Representative Bayesian curve-fitting examples of concentration–response profiles for individual chemicals (insets) and a representative designed mixture (AC50-H; see Table 1 for description) for total outgrowth in iCell neurons (results for all other phenotypes can be found in Supplemental Materials Figures S1–S94 and a Supplemental Excel file). See acronym explanations and description of the designed mixtures in Table 1. Dots represent experimental data points. Gray lines represent individual simulated curves from the last 100 iterations. The vertical dashed red lines represent the 90% credible interval on the point of departure (EC10).
