BIODEGRADATION IN WATER: SCREENING TEST

The registration substance is not readily and not inherently biodegradable (see IUCLID Chapter 5.2.1).

BIODEGRADATION IN WATER: SIMULATION TESTS

The registration substance is not readily and not inherently biodegradable in screening tests. In addition the estimated Koc (EUSES 2.1, organic acids) is 162 L/kg which means sorption to solids is low. In addition the registration substance has a low volatiliy. Based on these facts an elimination in an OECD 303A STP simulation test caused by biodegradation, sorption or volatilisation is not expected and therefore the test is not warranted. Due to the fact that the registration substance is not inherently biodegradable, is it not expected that rapid biodegradation occurs in freshwater.Therefore biodegradation simulations test using river water is not warranted. Due to the low sorption of the registration substance to solids, sediment is not a traget compartment. Based on the facts mentioned before a sediment biodegradation test is not warranted.

BIODEGRADATION IN SOIL

Due to the fact that the registration substance is not readily and not inherently biodegradable in screening test, it is not expected that rapid biodegradation would occur in soil. In addition the estimated Koc (EUSES 2.1, organic acids) is 162 L/kg which means sorption to solids is low. This means transfer of the registration substance from sewage sludge to agricultural soil is limited and therefore soil is not the target compartment. Based on these facts mentioned before a soil biodegradation test is not warranted.
