Additional information

The study performed by Nichetti (2013), is considered not realistic as the substance was founded to be volatile in several ecotoxicological and toxicological study report.


The VP value from the Bromos study (1980), the value reported in the NTP TR 594 and the calculated data from EPISuite 4.1 (based on Antoine & Grain methods) are comparable instead. For this reason a vapour pressure value of 1000 Pa was set.
