Workers - Hazard for the eyes
Additional information - workers
No additional DN(M)ELs for 2-MBA for workers, were/could be calculated for other human exposure pathways (listed below) because either the pathway(s) was not identified in the identified uses or there were no available/adequate data to use to calculate the DN(M)EL.
Dermal DN(M)EL for Acute/short-term exposure - systemic effects
Inhalation DN(M)EL for Acute/short-term exposure - systemic effects
Inhalation DN(M)EL for Acute/short-term exposure - local effects
Dermal DN(M)EL for Long-term exposure - systemic effects
Dermal DN(M)EL for Long-term exposure - local effects
Ocular DN(M)EL
General Population - Hazard via inhalation route
Systemic effects

Local effects
Acute/short term exposure
DNEL related information
General Population - Hazard via dermal route
Systemic effects
Acute/short term exposure
DNEL related information
General Population - Hazard via oral route
Systemic effects
Acute/short term exposure
DNEL related information
General Population - Hazard for the eyes
Additional information - General Population
No DN(M)ELs for 2-MBA for the general population were calculated because there were no identified exposure pathways.
