Acute Toxicity: inhalation
Administrative data
- Endpoint:
- acute toxicity: inhalation
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1976
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Remarks:
- Non GLP, no details on test material other than batch and substance code. As pigments are very stable substances and the composition for this substance code is available elsewhere, this is considered acceptable. Some experimental details not described in the report. Overall sufficient details and adequate study design.

- GENERATION OF TEST ATMOSPHERE / CHAMBER DESCRIPTION
- Exposure apparatus: The dust was generated by injecting the test material with the help of a "Grafix Exaktomat Injector" into an air stream which was discharged into the exposure chamber through a nozzle under a pressure of 2 atm. at a rate of 20 L/min.
- Exposure chamber volume: not applicable, as nose-only exposure
- Method of holding animals in test chamber: Rats were kept on separate PVC tubes positioned radially around the exposure chamber such that snout and nostrils of the animals only were exposed to the dust.
- Source and rate of air: 17.5 L/min
- Method of conditioning air: not indicated
- System of generating particulates/aerosols: The dust was generated by injecting the test material with the help of a "Grafix Exaktomat Injector" into an air stream which was discharged into the exposure chamber through a nozzle under a pressure of 2 atm. at a rate of 20 L/min.
- Method of particle size determination: The concentration and the particle size distribution of the dust in the vicinity of the animals was monitored at 1 hour intervals throughout the dust exposure. The size distribution of the dust particles was measured with a Cascade Impactor with selectron filters of 25 mm diameter and with a pore size of 0.2micrometer (Schleicher and Schuell) at an air flow rate of 17.5 L/min.
- Treatment of exhaust air: not indicated
- Temperature, humidity, pressure in air chamber: not indicated
TEST ATMOSPHERE
- Brief description of analytical method used: The concentration was determined gravimetrically by sampling the test atmosphere through a selectron filter of 50 mm diameter and with a pore size of 0.2 micrometer (Schleicher and Schuell, Feldbach, Switzerland) at an air flow rate of 10 L/min.
- Samples taken from breathing zone: indicated as "in the vicinity of the animals"
TEST ATMOSPHERE (if not tabulated)
