Default (DNEL calculator)

AF for dose response relationship:
1
Justification:
Default (DNEL calculator)
AF for differences in duration of exposure:
2
Justification:
Acute effect during the first 3 days of gestation period therefore a default assessment factor of 2 is considered conservative enough.
