Description of key information

Additional information

According to ECHA (ECHA, 2008: Chapter R7.c; Endpoint specific Guidance) readily biodegradable substances which are not directly applied to soil, it is generally assumed that the substance will not enter the terrestrial environment and as such there is no need for testing of soil organisms is required. Both criteria are fulfilled for 1,4 diaminobutane.


There is no soil exposure because there is no sludge application to land from the STP of DSM. Aerial deposition is negligible due to the reaction of the substance with carbondioxide in the air. Exposure pathways such as irrigation and/or contact with contaminated waste is unlikely.
