Applicant's summary and conclusion

Executive summary:

The potential environmental distribution of 2,2’-azobis(2-methylpropionitrile) is obtained from a generic Mackay level III fugacity model. The results show that, if 2,2’-azobis(2-methylpropionitrile) is released into water, it is unlikely to be distributed into other compartment. If 2,2’-azobis(2-methylpropionitrile) is released into air or soil, it is likely to be distributed in water and soil.
