In the model of Csanady et al. (1996), the biochemical parameters for butadiene in rats and mice were obtained by fitting model simulations to in-vivo data of Bolt et al. (1984) and Kreiling et al. (1986). The biochemical parameters for epoxybutene were identical to those of Johanson and Filser (1993, 1996). This model accurately predicted experimental data on epoxybutene. The most advanced models are those of Csanady etal. (1996) and Sweeney et al. (1997), since they can simulate both epoxybutene and diepoxybutane as metabolites of butadiene. The tissue blood partition coefficients for diepoxybutane were estimated by Csanady et al. (1996) to have a value of 1 for all tissues. Sweeney et al. (1997) obtained tissue blood partition coefficients from in-vitro measurements (Table 23). Both models yielded good predictions for mice and rats for both metabolites. For humans, no measured data have been reported against which the predictions could be validated. In addition, the model of Csanady et al. (1996) predicted accurately the measured haemoglobin adduct levels (Osterman-Golkar etal., 1993 Albrecht et al., 1993) of epoxybutene in rodents following exposure to butadiene. None of the models published has included the fonnation and elimination of epoxybutanediol.

Table VII lists threadlocking anaerobics and gives a general description of popular grades it is not comprehensive. This product type represents the majority of anaerobic business. Once cured in a nut and bolt or screw assembly, anaerobics prevent loosening due to vibration or impact. Data demonstrating these properties are voluminous. Threadlocking products come in different strengths and viscosities, required because of the variety of bolt and screw sizes. Smaller screws, for instance, require a lower strength product to allow nondestructive removal. Viscosities vary to accomodate thread density and the need to wick into preassembled fasteners. Threadlocking performance is measured in terms of the torque required to loosen the fastener after cure (breakaway torque) and the torque required to turn the nut or screw after breakaway (prevailing-out torque).
