The calculated half life for 1,4 diaminobutane is 0.162 days or 1.939 hours based on annually averaged daily 12 hr daylight hydroxyl concentration of 1.56E06 molecules (OH-radicals)/cm3 at 25 deg C. Source: QSAR program Atmospheric Oxidation Program (AOPWIN) v1.92 from the US-EPA (2000).Based on data of DSM (O. Poorter, 2002) the substance, when released into the air, reacts with carbondioxide to form a salt which is a solid substance. Since the substance is readily biodegradable, phototransformation in water is expected not to be a relevant mechanism.Since the substance is readily biodegradable, phototransformation in soil is expected not to be a relevant mechanism.
