Effect levels
- Dose descriptor:
- other: 8 hr IOELV
- Effect level:
- 50 ppm (nominal)
- Based on:
- test mat.
- Sex:
- male/female
- Basis for effect level:
- other: SCOEL concluded there was a great deal of human data demonstrating no reliable evidence of neurological effects at or below 50 ppm (192 mg/m3), hence 50 ppm was an appropriate level for an 8 hr TWA

Applicant's summary and conclusion
- Executive summary:
SCOEL noted that toluene exposures in the range 90-150 ppm (345-575 mg/m3) for several hours lead to decrements in neurological test results although some of the findings were difficult to interpret due to uncertainties regarding the relationship between the effects monitored and contemporary / past levels of exposure. However the availability of a great deal of human data indicated no reliable evidence of effects at or below toluene concentrations of 50 ppm (192 mg/m3). SCOEL therefore concluded that 50 ppm (8 hour TWA) was an appropriate level for an IOELV.
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).
