Environmental factors, etc. are the factors such as , etc. chemicals and infections that are in the environment around us . In the work environment exposed to benzene ( a type of chemical ) being the high amount of long term risk factors for AML to account comes . amount to much ( survivors of the atomic bomb or the events of nuclear reactors ) than others exposed to AML or ALL .
