- No. of animals per sex per dose:

- Control animals:
- yes, concurrent no treatment
- Details on study design:
- Three experiments were conducted. Control groups were exposed to uncontaminated air (without test substance). The initial experiment, doses of 1, 2, 5 and 20 ppm did not produce any signs of gross toxicity and so a second experiment using doses of 40 and 60 ppm were used. A third experiment was conducted (using doses of 100 and 150 ppm).

- CLINICAL SIGNS AND MORTALITY
- Mortality: Four rats from the 150 ppm group died during the first exposure, a further 2 died the following morning and 2 died during the second exposure. The remaining 2 rats from the 150 ppm group died by the 10th exposure (end of the second week). There were 6 deaths in animals exposed to 100 ppm after 46 days and 1 death following 4 days exposure to 60 ppm allyl alcohol.
-Clinical signs: Clinical signs in the 150 ppm group included gasping, severe depression, nasal discharge, eye irritation and corneal opacity. Less intense clinical signs were present in animals exposed to 40-100 ppm. Clinical signs were absent in animals exposed to 20 ppm and below.
BODY WEIGHT AND WEIGHT GAIN
Mean percentage body weight gain was statistically significantly lower in animals exposed to 20 ppm (see table 1).
ORGAN WEIGHTS
Relative kidney weights increased by 8-10% in animals exposed to 40 ppm or 60 ppm allyl alcohol vapour for 12 weeks. Relative lung weight was increased after exposure to 40 ppm allyl alcohol vapour for 12 weeks. Relative liver weights for treated animals were indistinguishable from those of the controls. (see table 1).
GROSS PATHOLOGY
Livers from rats in the 150 ppm allyl alcohol group appeared haemorrhagic and lungs were pale and spotted. The kidneys appeared normal.
HISTOPATHOLOGY: NON-NEOPLASTIC
At the 150 ppm dose group microscopic examination revealed slight congestion of the lungs and liver. At the 100, 60 and 40 ppm groups, lesions and microscopic finding were similar to that of the 150 ppm dose group but less intense.

Applicant's summary and conclusion
- Conclusions:
- In this study the NOAEL and LOAEL for repeated dose toxicity via the inhalatory route in rats were 20 ppm (47.5 mg/m3) and 40 ppm (95.1 mg/m3) respectively.
- Executive summary:
In a subchronic inhalation toxicity study allyl alcohol was administered to 10 male rats (Long-Evans strain) per concentration group, by whole body exposure, at concentrations of 0, 1, 5, 20, 40, 60, 100 and 150 ppm for 7 hours per day, 5 days/week over 12 weeks. Treatment-related clinical signs were observed, beginning at 40 ppm, with treatment-related mortality observed at 60 ppm or higher.
The LOAEL was 40ppm, based on increased lung weight and clear retardation of weight gain. The NOAEL is 20 ppm .
