Any other information on results incl. tables

Deaths occurred at concentrations of 790 ppm (2/10 rats died), 834 ppm (5/10 rats died) and 896 ppm (8/10 rats died). Clinical signs at exposure included cyanosis, tremors and prostration up to 48 hours post-exposure, corneal clouding up to 14 days post-exposure, reddish brown nasal discharge and chromodachryorrhea. Clinical signs post exposure were pallor and rales, head and facial hair loss; after 4 hours exposure to 790 ppm mild to severe corneal damage was detected.
