Administrative data

acute toxicity: inhalation
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because exposure of humans via inhalation is not likely taking into account the vapour pressure of the substance and/or the possibility of exposure to aerosols, particles or droplets of an inhalable size
Justification for type of information:
The particle size distribution of the test item was determined as follows: D10 = 15.3 µm, D50, median particle size = 43.1 µm and D90 = 129.8 µm.
It needs to be considered that the substance is supplied with antidusting oil which reduce the production of fine powder during the exposure.
