Any other information on results incl. tables

Sublethal observations / clinical signs:

All results are expressed in terms of mean measured concentration. Measured concentrations ranged from 86.6 to 94.4% of nominal at 0 hours, 85.8 to 98.3% of nominal at 24 hours, 85.7 to 93.0% of nominal at 72 hours and 81.3 to
89.8% of nominal at 96 hours. These results show that near nominal concentrations were achieved and maintained
throughout the exposure period.
