Results and discussion

Results:
Odour was unpleasant and recognised by all subjects at 2.5 ppm. Eye and nose irritation, pulmonary discomfort and CNS effects (slight headache, nausea) were also noted by some at this level.

At 14 ppm irritation of eyes, nose and throat, and pulmonary discomfort were considered intolerable, and exposure was terminated at once.

There was no icrease in CNS effects with increasing concentration, apparently.

Applicant's summary and conclusion

Conclusions:
In humans, allylamine is easily detected at 2.5 ppm, and is intolerable at 14 ppm.
Executive summary:

Volunteers exposed in whole body chambers to concentrations of 2.5, 5 and 10 ppm allylamine, and briefly to 14 ppm.

Odour was unpleasant and recognised by all subjects at 2.5 ppm. Eye and nose irritation, pulmonary discomfort and CNS effects (slight headache, nausea) were also noted by some at this level. At 14 ppm irritation of eyes, nose and throat, and pulmonary discomfort were considered intolerable, and exposure was terminated at once. There was no icrease in CNS effects with increasing concentration, apparently.
