- GENERATION OF TEST ATMOSPHERE / CHAMBER DESCRIPTION
- Exposure apparatus: 1000 L stainless steel and glass exposure chambers; chambers contained catch pans between each of three leveles of cages.
- System of generating particulates/aerosols: The test material was aerosolized directly from the liquid by a modified Lakin nebulizer on each chamber. The test material was in a straight-walled glass flask and the barrels of the nebulizer were immersed under the level of the liquid in order to maximize the amount of material generated. The distance from the nebulizer to the walls of the flask was approx. 3 cm. After exiting the flask, the aerosol passed through a glass impactor to remove most of the larger particles. The remaining aerosol was mixed with the main air stream for each chamber before entering the chamber.
- Temperature and humidity in air chamber (by a Taylor wet/dry bulb hydrometer approx. every 30 min during each exposure): approx. 23 °C, 56 - 64%
- Air flow rate: approx. 300 L/min (mean chamber flow per group: 297, 308, 342, and 243 L/min, respectively)
TEST ATMOSPHERE
- Brief description of analytical method used: gravimetric sampling on glass fiber filters (3 times during each exposure); some filters were additionally analyzed by GC/MS
- Samples taken from breathing zone: yes
Nominal concentrations were determined as the loss of weight of fluid from the generator divided by total air flow through the chamber. - Analytical verification of doses or concentrations:
- yes
- Duration of treatment / exposure:
- 13 weeks
- Frequency of treatment:
- 6 hours/day
5 days/week

- No. of animals per sex per dose:
- 15
(Additional 10 male rats per group were included for examination of pulmonary function tests and analysis of pulmonary hydroxyproline following exposure.) - Control animals:
- yes, concurrent no treatment
- yes, sham-exposed
- Details on study design:
- - Dose selection rationale: The highest dose was expected to result in abnormal accumulation of test material in the lung and possible impairment of normal clearance mechanisms. The low dose is a factor of 10 above the TLV (treshold limit value) for mineral oil mistes, no untoward effects were expected at this level.

OTHER:
Lung function: The animals were anaesthetized and pulmonray function tests were performed (deflation quasistatic pressure-volume cureved, functional residual capactiy, and maximal forced exhalation maneuver). After the pulmonray function tests, the lungs were removed and all lobes were weighed. Lobes were frozen for analysis of hydroxyproline content and analysis of test material remaining in the lung. - Sacrifice and pathology:
- GROSS PATHOLOGY: Yes; organ weights (adrenals, kidney, spleen, brain, liver, testes, epididymides, ovaries, thymus, heart, prostate, uterus, right middle lung lobe
HISTOPATHOLOGY: Yes (untreated and high-dose): adrenals, ovaries, sternum, pancreas, brain, salivary gland, eye, spleen heart, stomach, colon, testes, duodenum, thymus, kidneys, thyroid, liver, tracheobronchial lymph nodes, lung, nasal turbinates, thigh muscle, urinary bladder, sciatic nerve, and any gross lesions. Only the lungs and tracheobronchial lymph nodes of the untreated controls were processed. 10 males of group 1, 2 and 5 (untreated, sham-exposed, and high-dose) were evaluated for morphology, number of sperm and number of testicular spermatids. - Statistics:

BODY WEIGHT AND WEIGHT GAIN
Increased body weights were observed in treated males. The difference compared to control was statistically significant, but as no clear dose-response was seen and the difference was lower than 7%, it was not considered to be of toxicological relevance.
HAEMATOLOGY
No treatment-related changes were observed.
CLINICAL CHEMISTRY
No treatment-related changes were observed.
ORGAN WEIGHTS
The lungs had a minimal increase in weight after exposure to 0.50 mg/L. Other organ weights were not affected by exposure to the test substance.
GROSS PATHOLOGY
The number of macrophages in the pulmonary alveoli increased slightly. This increase was small considering the high (500 mg/nr) aerosol concentration.
HISTOPATHOLOGY: NON-NEOPLASTIC
Microscopic examination of the lungs of animals in the high-dose group revealed one to two plump macrophages with sparse cytoplasmic vacuoles in less than 1.0% of the aveoli (in controls less than 0.1% would be expected).
OTHER FINDINGS
- Sperm morphology: No treatment-related effects were noted in sperm morophology or in sperm and spermatid counts.
- Lung function: There were no significant differences between any groups for any of the pulmonary function parameters. The only parameter affected by exposure was the total weight of the five lung lobes. Weight for the high-dose group was significantly greater than the other groups.
