Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

General Population - Hazard via oral route

Systemic effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
0.13 mg/kg bw/day
Most sensitive endpoint:
repeated dose toxicity
Route of original study:
Oral
DNEL related information
DNEL derivation method:
ECHA REACH Guidance
Overall assessment factor (AF):
37.5
Modified dose descriptor starting point:
LOAEL
Value:
9.75 mg/kg bw/day
Explanation for the modification of the dose descriptor starting point:

no route to route extrapolation performed

AF for dose response relationship:
3
Justification:
Although the observed effects were minimal, a 3 fold factor was included to be protective.
AF for differences in duration of exposure:
1
Justification:
chronic
AF for interspecies differences (allometric scaling):
1
Justification:
Factor for allometric scaling: any metabolism of inorganic substances can be excluded. Therefore, it is considered justified to deviate from default assessment factors accounting for a correction for differences in metabolic rate by assigning a factor of “1” instead of using the default factor of 4.
AF for other interspecies differences:
2.5
AF for intraspecies differences:
5
Justification:
The assessment factor is introduced since it is expected that a greater variability in response from the most to least sensitive human would be seen, relative to an experimental animal population. ECETOC (2003) has reviewed scientific literature on the distribution of human data for various toxicokinetic and toxicodynamic parameters to assess intraspecies variability within the human population, specifically by Renwick and Lazarus (1998) and Hattis et al. (1999). Considering that the data analysed by these authors include both sexes, a variety of disease states and ages, the use of the 95th percentile of the distribution of the variability for these datasets is considered sufficiently conservative to account for intra-species variability for the general population. Based on this, a default assessment factor of 5 is recommended by ECETOC (2003) for the general population.
AF for the quality of the whole database:
1
Justification:
several supportive studies exist
AF for remaining uncertainties:
1
