Following repeated daily exposure of the
male and female rat to the vapour (7 hours a day for 31 days over a 44
day period), only reversible clinical signs were observed at 5000 ppm;
there were no effects on body weight, necropsy or pathology of major
organs. There were no effects at 3000 ppm. 5000 ppm
is therefore considered to be the LOEL. This
was a none standard experiment, but the results are in a similar region
as that reported by other investigators.
