The substance is not readily biodegradable. However, biodegradation
studied in a water-sediment simulation test (Dow, 1995) demonstrated
test substance mineralisation of 64% after 60 days of exposure,
indicating non persistence of the test item in water and sedimet.
Further, as the logKoc is below 3 even if the partly cationic character
of the molecule was considered, a low adsorption potential is indicated.
Therefore, binding to sewage sludge is unlikely and as a consequence a
transfer to the sediment is not expected. Therefore, no tests on
sediment dwelling organisms are provided.
In addition, the predicted no effect concentration (PNEC) for sediment
was derived from the PNEC for freshwater using the equilibrium
partitioning method. Using this PNECsediment, the risk characterization
shows that the PEC/PNECsediment ratio for the sediment environment is
clearly <1, indicating no need for further information and testing.
