- Vehicle:
- other: unchanged (no vehicle)
- Details on inhalation exposure:
- GENERATION OF TEST ATMOSPHERE / CHAMBER DESCRIPTION
- Exposure apparatus: cylindric inhalation chamber "INBIFO-MAKROLON-Tierrohre Typ 1" with stainless steel head cones, according to KIMMERLE apparatus with 20 animal tubes
- Exposure chamber volume: 40 L
- Method of holding animals in test chamber: cylindric tube
- Source and rate of air: 7.11 L air flow/min
- Method of conditioning air: 0.2 mL of test substance per min was pumped using a dosing pump (BRAUN, Melsungen, Germany)
- System of generating particulates/aerosols: aerosol nozzle, nozzle orifice 0.15 mm (BUNDSCHUH, Griesheim, Germany)
- Measured test substance concentration in inhalation chamber: 28.1 µL/ L air
"Zyklon" (BCRIA sampler) was used to sample precipitated particles with a particle size > 5 µm
A cambridge filter was used to sample respirable particles.
Gravimetric analyses were performed to determine the respirable test substance concentration.
TEST ATMOSPHERE
- Brief description of analytical method used: during exposure every hour the aerosol concentration was measured in the inhalation chamber directly in the area of animals noses (head cones)
- Samples taken from breathing zone: yes
TEST ATMOSPHERE (if not tabulated)
- MMAD (Mass median aerodynamic diameter) / GSD (Geometric st. dev.): 1.97 µL test substance / L air was < 5 µm diameter - Analytical verification of test atmosphere concentrations:
- yes
- Remarks:
- Gravimetric analyses were performed to determine the respirable test substance concentration.
- Duration of exposure:
- 6 h
- Concentrations:
- 28.1 µL/L air (calculated concentration)
measured respirable test substance concentration: 1.97 µL/ L air (< 5 and < 10 µm diameter particle size) - No. of animals per sex per dose:
- 10
- Control animals:
- other: yes, sham-exposed
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations: during exposure, after exposure and thereafter daily
