In Fig. 1, the bars represent the average mercury vapor concentrations (from Table 4) for 15 and 30 min and 1-h and averaged maximum mercury vapor concentrations from the Maine study scenario S1 (Stahler et al., 2008) at 1-ft and 5-ft heights from the floor. These are compared with relevant short-term toxicity benchmarks (from Table 6). Please note the use of a log scale for the yaxis in this and other figures.
