- GENERATION OF TEST ATMOSPHERE / CHAMBER DESCRIPTION
- Exposure apparatus: stainless steel and glass chamber
- Exposure chamber volume: 250 litres
- Total air flow: 2.2 cubic feet per minute
- Temperature, humidity, pressure in air chamber: test substance was introduced in a vertical counter column heated to approximately 50 degrees celsius
TEST ATMOSPHERE
- Brief description of analytical method used: the test atmosphere was analyzed by a Miran 980 infrared (IR) analyzer at intervals of five to fifteen minutes after testing commenced. The test atmosphere was analyzed gravimetrically and visually (via flashlight) for aerosols . Gravimetric measurements were generated by drawing a calibrated volume of the test atmosphere through a preweighted 25 mm Gelman Metricel filter and dividing the difference in filter weight by the sample volume. Components of the generation system and test container were weighed before and after the exposure to determined the quantity of test material consumed. The quality was divided by the total air flow through the chamber to determine the nominal exposure concentration
- Samples taken from breathing zone: yes
- Analytical verification of test atmosphere concentrations:
- yes
- Duration of exposure:
- <= 4 h
- Concentrations:
- mean analytical concentration of 5.28 mg/L petroleum derived hydrocarbon
- No. of animals per sex per dose:
- five animals per sex were exposed
- Control animals:
- not specified
- Details on study design:
- Five animals per sex were exposed to 5.28 mg/L of the test substance during a single 4 hour whole body inhalation exposure. Animals were introduced to the test substance in a 250 litre stainless steel and glass chamber. Total airflow through the chamber was 2.2 cubic feet per minute. API 83-09 was generated as a vapour and flowed into the chamber at a rate of 0.34 to 0.51 ml/minute from the top of a vertical counter current heated column. Prewarmed nitrogen was introduced from the bottom of the column at a rate of 7.0 L/minute. The nitrogen and test substances were mixed with air before introduction into the chamber. After 4 hours of exposure the test material generation system was turned off and residue cleared. Test animals were removed from the testing chamber and observed for fourteen days post exposure. Surviving animals were sacrificed and a gross post-mortem examinations were preformed.
- Statistics:
- The mean analytical exposure values were calculated, along with the nominal-to-analytical ratio.
Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LC50
- Effect level:
- > 5.28 mg/L air (analytical)
- 95% CL:
- 0.42
- Exp. duration:
- 4 h
- Remarks on result:
- other: Based on lack of mortality and systemic effects
- Mortality:
- No test animals died during exposure or the post-exposure observation period.
- Clinical signs:
- other: Rats were monitored for decreased activity, soft feces, coat consistency and colour, squinted eyes, and body weight. All animals exhibited decreased activity during the third and fourth hour of exposure and on the second and third days following exposure
- Body weight:
- On day eight of the study, one male rat's body weight was recorded as less than his pre-exposure body weight. By test day fifteen, it was back to normal. No significant changes in body weights were noticed, for any other test animal, throughout the study.
- Gross pathology:
- During gross pathology observations, four sections of the lung were examined. The pathology report indicated that no significant histological alternations were seen.
Any other information on results incl. tables
All animals survived the study. Physical examination, body weight observations, and gross post-mortem and histopathological results were considered insignificant.
Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Based on zero mortality and absence of significant toxicity, body weight observations, and gross post-mortem and histopathological results, in the lungs, it is concluded that straight run kerosine does not have acute toxic effects under the conditions of this study.
- Executive summary:
In an acute inhalation toxicity study, groups of Sprague-Dawley rats, five males and five females, were exposed by inhalation route to a petroleum derived hydrocarbon for 4 hours to their whole body at a single dose of 5.28 mg/L. Animals were then observed for 14 days afterwards.
All animals survived the study. Physical examination, gross port-mortem and histopathological results were considered insignificant. One male rat's body weight was recorded as less than his pre-exposure body weight during post-exposure examinations, but returned to normal before being sacrificed. No significant changes in body weights were noticed, for any other test animal, throughout the study. The analytical NOAEC for this study is >5.28 mg/L air. The test material is not classified according to EU criteria due to no upper limit of the NOAEC.
This study received a Klimisch score of 1 and is classified as reliable without restriction because it was carried out in a method similar/equivalent to OECD TG 403.
