Administration / exposure
- Route of administration:
- inhalation: dust
- Type of inhalation exposure:
- nose/head only
- Vehicle:
- other: melange of substance dust and air
- Details on inhalation exposure:
- GENERATION OF TEST ATMOSPHERE / CHAMBER DESCRIPTION
- Exposure apparatus: Head/Nose-Inhalation System INA 20 (Glas-Steel-Construction, BASF AG) (animals were sitting in a tube with the snout rising into the inhalation chamber.
- Exposure chamber volume: 55 L
- Source and rate of air: Compressed air (1500 L/h), air for dilution (1500 L/h)
- System of generating particulates/aerosols: A Dust-Air-mixture was generated with a rotating brush generator (TH - Karlsruhe/BASF). Adjustment of concentration was performed by means of variable rotation of the rotating brush generator and by variable piston setting.
- Method of particle size determination: At least 30 minutes after beginning of the study, an air sample of 30 L was taken and the particles sizes were analysed by means of a Stack Sampler Mark III (Andersen ) and gravimetrical determination.
- Temperature, humidity, pressure in air chamber: 19-25°C, excess pressure (outlet air was 10% less than inlet air)
TEST ATMOSPHERE
- Brief description of analytical method used: air sample was taken from the breathing zone with a vacuum pump and filtered (MN 85/90 8f; d = 4,7 cm). A sample of one liter air (1.25 m/s) was taken every hour. The amount of dust was determined by gravimetrical analysis of the filter weight before and after sample taking.
- Samples taken from breathing zone: yes
TEST ATMOSPHERE (if not tabulated)
- Particle size distribution:
- MMAD (Mass median aerodynamic diameter) / GSD (Geometric st. dev.): 5.7 µm/2.6
- Rationale for the selection of the starting concentration: The concentration was chosen based on the results of the acute oral toxicity study. - Analytical verification of test atmosphere concentrations:
- yes
- Duration of exposure:
- 4 h
- Concentrations:
- 2 mg/L
- No. of animals per sex per dose:
- 5
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Recording of signs and symptoms several times on the day of administration, at least once each workday. Check for moribund and dead animals at least once daily. Weighing was performed before study begin and after 7 and 14 days.
- Necropsy of survivors performed: yes - Statistics:
- Dose-response relationship:
On the basis of the binominal-test (Wittig, H.: Mathematische Statistik, 1974, page 32 -35), according to the tables of the BASF Rechenzentrums .
Calculation of particle size distribution was performed on the basis of mathematical methods for particle measurements (Silverman, L.: Particle Size Analysis in Industrial Hygiene, 1971, S. 235 - 259) in the Department of Toxicology (BASF AG).
Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LC50
- Effect level:
- > 2 mg/L air
- Exp. duration:
- 4 h
- Mortality:
- No mortality occurred
- Clinical signs:
- other: During exposition: nose discharge (reddish), salivation, accelerated respiration After exposition: fur smeared (bloody, near head), accelerated/irregular respiration, respiratory sounds, piloerection All symptoms were reversible within 5 (males) and 8 (fe
- Body weight:
- No difference between the weight gain of the test group and the historical control in the males. The weight gain of the females was delayed during the first week, but adjusted to a normal weigt gain during the second week post exposure (details see table 1 "Any other information")
- Gross pathology:
- No abnormalities observed.
