CAS 74-83-9 -

CAS Number:  74-83-9

Chemical Name:  Methyl bromide, as a structural fumigant

Type of Toxicity:  developmental

Listing Mechanism:  Formally Required to be labeled or identified (FR)

Date Listed:  1-Jan-93

NSRL (No Significant Risk Level) or MADL (Maximum Allowable Dose Level):  810 (inhalation) µg/day

Where a source or product results in exposures by multiple routes, the total exposure must be considered. For example, the MADL for benzene is exceeded when the absorbed dose exceeds 24 µg/day. If only inhalation and oral exposure occurs, the benzene MADL is exceeded when: (oral dose ÷ 24 µg/day) + (inhalation dose ÷ 49 µg/day) > 1.0.
