B2 Emission profile The emission profile for the mechanically ventilated scenario shows that all the contaminants produced by the detonation are exhausted from the Site 5 in under 20 minutes. The emission profile for each contaminant from Site 5 are shown inAppendix B Figure 2to Appendix B Figure 4. The NOX profile was prepared assuming all emitted NO is instantaneously converted to NO2 upon release. The instantaneous concentration of each contaminant in parts per million as provided in the Gas Dispersal Study inAppendix A has been converted to milligrams per cubic meter using the molar mass of the contaminant and the volume of 1 mol at atmospheric pressure and 20°C.
