Results from a preliminary study, summarised in tabular form, indicate
that there was 33-67% mortality following 4 hr exposure to 2000 ppm PDC
(equivalent to 9.4 mg/l). There were 3/6 deaths in the definitive study
following an 8 hr exposure to this same concentration. Thus the same
extent of mortality was observed in rats exposed to PDC vapor for 4 hr
or 8 hr. Since the longer exposure was not more hazardous than the
shorter expsoure, it is concluded that these results most likely reflect
the 4 hr acute toxicity of 1,2-dichloropropane in the rat.
