NCV – nerve conduction velocity, in m/sec; NCV data from: Table 4 in Calleman et al. (Calleman et al., 1994); ACM conc. – facility average exposure conc., mg/m³; XR – exposure response: XR= (NCV(Ref)-NCV(ACM)/ACM; XR in (m/sec)/(mg/m³) = m⁴/mg.sec; MCV – motor conduction velocity; SCV – sensory conduction velocity
