Figure 3. Mean hazard quotients (HQs) simulated by MCS for OPE exposure via home dust: (A) HQ variation among cities; and (B) HQ variation by age group. MCS: Monte Carlo simulation; OPE: organophosphate ester; TCEP: tri(2-chloroethyl) phosphate; TCIPP: tris(chloroisopropyl) phosphate; TDCIPP: tris(1,3-dichloro-2-propyl) phosphate; TEHP: tris(2-ethylhexyl) phosphate; TMCP: tricresyl phosphate; TPPO: triphenylphosphine oxide.
