Results and discussion
Applicant's summary and conclusion
- Executive summary:
Inhalation experiments with increasing concentrations from 50-1000 ppm (2050 ppm in one case). Duration of exposure was up to 7 h at concentrations up to 250 ppm and up to 2 h at concentrations up to 2050 ppm. 10 ppm was the level at which the substance was noticeable. Above 100 ppm people had a temporarily smell-irritation, after 1-2 h exposure time the eyes were slightly irritated. At 300 ppm people had mild eye- and nose irritations within 5 minutes and after 1 h irritations were only hardly bearable. 750 ppm was scored as very strongly irritating. At 1000 ppm indications of a CNS-depression were recognized. Breath analysis data showed that PM was rapidly excreted via the lungs. The human volunteers all experienced a rapid development of odor tolerance. Hence, unless prompt action is taken when objectionable odor is experienced, it cannot be relied upon to prevent exposures that might be hazardous. However, because the odor is readily detected and is objectionable PM vapors are considered to have adequate warning properties, if needed. Neurologic, clinical, chemical and general medical studies didn't show any significant abnormalities.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
