Additional information

The pKa value of 9.34 (Sparc online calculation, v4.2, 2008) indicates that aziridine will predominantly exist as a cation in the environment, therefore the partition cofficient (logD) was calculated for the environmental relevant pH values. Based on these calculations (logD values at pH 4, 7, 9 are -1.16, -2.68 and -2.95) bioaccumulation is not to be expected.
