Additional information

There are no data describing the long-term toxicity of the registered substance to terrestrial arthropods.

However, an earthworm reproduction test (OECD 222) and a soil microorganism test (OECD 216) have been conducted with the registration substance, D6.

No effects were observed in the tests and the test substance showed analytical recoveries close to the nominal concentrations during the earthworm study, therefore the test organisms are expected to have been exposed to significant concentrations of test substance.

As no effects were observed, no PNECsoil was derived.


The earthworm is the standard organism for soil macroorganisms and there is no indication that arthropods would be any more susceptible, therefore the data generated from the earthworm reproduction test and soil microorganism test are considered to be suitable to derive hazard and risk assessment under REACH for D6 and the requirement for further tests with terrestrial arthropods is waived.
