Any other information on results incl. tables
Reported effects at 200 ppm: 30% mortality; elevated heart, liver, kidney and lung / w ratios; decreased bw gain; microscopically, heart lesions were found in 11 of 15 rats.
Repeated exposure of rats to diallylamine (fifty 7-hour exposures to 200 ppm) caused changes in liver and kidney weights, a reduction in growth, and mortality. Chemical pneumonia and myocarditis were also present in some rats (rats not specified).
Applicant's summary and conclusion
- Conclusions:
- Repeated inhalation exposure to diallylamine resulted in deleterious effects on heart and vascular tissue of rats.
- Executive summary:
Male rats were exposed to 0, 25, 50, 100 or 200 ppm of diallylamine vapour for seven hours/day for 50 days in order to assess cardiac and other organ system toxicity.
The No Observed Effect Level (NOEL) was considered to be 25 ppm based on the absence of any effects at this level. The No Observed Adverse Effect level (NOAEL) was considered to be in the range of 50 -100 ppm based on the absence of cardiac lesions at these levels, but there was an elevated heart to bodyweight ratio.
