Test animals
- Species:
- rat
- Strain:
- Fischer 344
- Sex:
- male
- Details on test animals or test system and environmental conditions:
- Male Fischer 344 (F-344) rats, 6 - 8 weeks of age, were obtained from Charles River Breeding Laboratories, Inc., Kingston, NY. Selection of this species and strain was based on its hardiness, low incidence of respiratory disease and extensive historical data. Upon arrival at the laboratory, the rats were examined for health status by a qualified professional and acclimated to the laboratory for a minimum of two weeks prior to exposure. Animals were fed Purina Certified Rodent Chow #5002 (Ralston Purina Co., St. Louis, MO) and water ad libitum except during exposure. The rats were weighed, randomised by weight, and individually identified with a metal ear tag. Prior to and after exposure, the rats were placed in rooms designed to maintain adequate environmental conditions concerning temperature and humidity specific for the species. The animals were group-housed prior to exposure and singly housed during exposure and the two-week post-exposure period.
Administration / exposure
- Route of administration:
- inhalation: vapour
- Type of inhalation exposure:
- whole body
- Vehicle:
- air
- Details on inhalation exposure:
- Exposure Chambers.
Whole body exposures were conducted in 1 cubic meter stainless steel and glass Rochester-type chambers. Groups of six male rats were exposed to a targeted vapour concentration of 129 ppm, for six hours. This was the maximum practically attainable concentration of propylene diacetate in the air.
The relative humidity value as well as maximum and minimum temperature values were recorded at the end of the exposure period.
Test Atmosphere.
The test atmosphere was generated by metering the liquid test substance at a calculated rate into a J-tube assembly. Compressed air was heated with a flameless heat torch (Master FHT-4) to the minimum extent necessary to vaporise the test material. Air passing through the J-tube was diluted with the main chamber airstream prior to entering the chamber.
The concentration of test substance in the exposure chamber was measured at least three times per hour by infrared spectrophotometry using a MIRAN IA infrared gas analyser at a wavelength of 8.2 um. Standards of known concentrations were prepared by vaporising measured amounts of test substance in 100 L Saran bags filled with a measured volume of filtered, dry air.
Standardisation was checked prior to exposure with a standard of known concentration. The nominal concentration (ratio of the amount of test substance vaporised to the total amount of air through the chamber) was calculated for the 6 hour exposure period. - Analytical verification of test atmosphere concentrations:
- yes
- Duration of exposure:
- 6 h
- Concentrations:
- 129 ± 3 ppm
- No. of animals per sex per dose:
- 6 male rats
- Control animals:
- no
- Details on study design:
- Animal Observations.
All rats were weighed and observed prior to exposure. All animals were observed at least daily during the two-week post-exposure period for signs of exposure-related effects. Morning and week-end monitoring was limited to animal husbandry procedures required to ensure availability of feed and water. All rats were weighed on test day 1, 2, 5, 8, 12 and 15 and submitted for gross necropsy examination by a veterinary pathologist. - Statistics:
- Mean and standard deviations of animal body weights were calculated for descriptive purposes.

- Mortality:
- All of the rats survived the 6 h exposure period and the 14 days observation period.
- Clinical signs:
- other: During exposure, all rats appeared normal and no exposure-related effects were noted during the two-week post-exposure period.
- Gross pathology:
- Gross pathologic examination of the animals showed no abnormal findings.
- Other findings:
- Animals were exposed to a Time Weighted Average (TWA) concentration of 129 +/- 3 ppm test substance for six hours. This was a maximum practically attainable concentration of the test item in the air. The nominal concentration was 109 ppm. The reason for the difference between the nominal and analytical values is not known. Total chamber airflow was 202 l/min.
