- Executive summary:
The half-life period of 2 -bromoethanaminium bromide (CAS No. 2576 -47 -8) in soil was estimated using Level III Fugacity Model by EPI Suite version 4.1 estimation database (EPI suite, 2017). If released into the environment, 77.5% of the chemical will partition into soil according to the Mackay fugacity model level III. The half-life period of 2-bromoethanaminium bromide in soil is estimated to be 30 days (720 hrs). Based on this half-life value of 2-bromoethanaminium bromide , it is concluded that the chemical is not persistent in the soil environment and the exposure risk to soil dwelling animals is moderate to low.
