A seven day transformation/dissolution test according to the OECD
guideline 29 and the GHS (Annex 10) protocol was run on Co3O4 at a mass
loading of 10 and 100 mg/L, at a pH of 6.0 Also a 28 day
transformation/dissolution was run on Co3O4 at a mass loading of 1 mg/L
and at a pH of 6.0. Under the conditions of this test, the dissolution
of Co3O4 is 1.03 on a log10 -scale for the 28 -day endpoint (1 mg/L
loading), 1.41 on a log10 -scale for the 7 -day endpoint (10 mg/L
loading) and 2.12 on a log10 -scale for the 7 -day endpoint (100 mg/L
