Additional information - workers

1. Identification of relevant dose descriptor

In an in-utero and life time study performed on a astructural analogue in rat , the substance did not cause mortalities, toxicity to reproduction and development or any adverse effects. The NOAEL is considered to be 30 mg/kg bw/d.

2. Mode of action

No non-threshold mode of action is associated with the test substance. In particular, the test substance has no genotoxic potential.

3. Application of assessment factors

Allometric scaling: rat to human = 4

Intraspecies factor: worker = 5, general population = 10

Exposure duration chronic to chronic: 1

Quality of data base: 1

Dose response: 1

4. Daily exposure

Worker: exposed for 8h

General population: exposed for 24h

Calculation of DNEL bases upon Guidance Document on Dermal Absorption, European Commission, 2004 and Guidance on information requirements and chemical safety assessment Chapter R.8: Characterisation of dose [concentration]-response for human health, may 2008
