Table 2.

Predicted peak brain chlorpyrifos (CPF) concentrations for the rat using the three dosing conditions (once daily, oral gavage CPF) reported by Yan et al. (2012).

Dose (mg/kg)	Peak brain CPF ($\mathrm{\mu }\mathrm{M}$)
0	0
1	$9.13\times {10}^{-4}$
5	$4.62\times {10}^{-3}$
10	$1.02\times {10}^{-2}$

Note: Peak brain CPF represents the simulated peak concentration of CPF in the brain for each exposure using the Poet et al. (2014) physiologically based pharmacokinetic (PBPK) model.
