- GENERATION OF TEST ATMOSPHERE / CHAMBER DESCRIPTION- Exposure apparatus: samples were dosed by WDFU (Wright Dust Feed Unit MK2, GA 4170, L. Adams, LTD., London) diredtly into an inhalation chamber, where they were dispersed through the spray; the atmosphere inside the inhalation chamber was homogeneous.- Method of holding animals in test chamber: animals were fixed in a glass tube of diameter 60 mm so that the face of the glass cylinder to interfere with the vertical axis - 250 mm in diameter- in which there was a linear dynamic atmosphere exchange at 8 l/min.- Source and rate of air: compressed air was taken from the central distribution Synthesia. Air flow was measured continuously throughout the exposure.TEST CONDITIONS- The average air flow apparatus: 0.360 m3/h- The temperature inside the apparatus: 22°C- Relative humidity inside the apparatus: 45-48 %- Actual concentration: 5.044 mg/L airTEST SUBSTANCE- Particle size of the test substance: : diameter 1-4: 409.7 ± 11.86 (85.55 %); diameter 4-10: 53.6 ± 3.72 (11.19 %); diameter 10-20: 13.6 ± 1.42 (2.84 %); diameter >20: 2.0 ± 0.5 (0.42 %)

- Effect level:
- > 5 mg/L air
- Based on:
- test mat.
- Exp. duration:
- 4 h
- Mortality:
- During the test and during the observation period (14 days) there was no mortality of the tested animals.
- Clinical signs:
- other:
- Body weight:
- The increase of body weight of animals tested was in according to the trend of increase of control animals.
- Gross pathology:
- Immediately thereafter after the 14-day observation period the animals were killed . After an autopsy was performed, focusing on the overall examination of the body surface and orifices, and macroscopic examination of the thoracic, abdominal and selected organs - trachea, lungs, heart, thymus, liver, spleen and kidneys.In one male was present a diffuse pulmonary congestion. In females were observed different effect: - Female 1: numerous punctate hemorrhages on the right lung. No other pathological anatomical findings. - Female 2: No pathological anatomical findings. - Female 3: sharply defined deposits a small pea size founded in the right lung. In the left lung were observed edema. - Female 4: grey-blue sharply defined deposits with size from pinehead to pea were observed in both lungs.- Female 5: Similar findings has been identified as female 4.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- A sample of Direct Red 80 were tested for limit test for acute inhalation toxicity. During the exposure or during the 14-day observation period there was no death of animals tested. Immediately after the application fault tracing (discharge from the eyes and nose, swelling of the eyelids, conjunctival hyperemia, and irregular breathing) can be considered reversible, nonspecific irritant highly concentrated aerosol dust on the exposed upper respiratory tract mucosa, and conjunctivitis.Symptoms of these changes within 2 days subsided and the course of the 14-day observation period revealed no fault condition in test animals. They were recorded also no differences according to sex of the animals. The reaction of males and females were the same.Autopsy revealed no overall or bearing, macroscopically detectable pathological-anatomical changes.The results of the limit test revealed no adverse effects of test substances on the health of experimental animals.
- Executive summary:
- Direct Red 80 was tested for acute inhalation toxicity. During exposure and during the 14-day observation period there was no mortality of experimental animals. Based on the results, the tested substance could be considered not toxic for acute toxicity for inhalation.
