Acute toxicity study in the earthworm Eisenia fetida fetida with SETAFIX Z1077.

The study procedures described in this report were based on OECD guideline for Testing of Chemicals No. 207 (adopted April 4, 1984). In addition, the procedure was designed to meet the test methods prescribed by Council regulation (EC) No 440/2008 of 30 May 2008, Part C: Methods for the determination of ecotoxicity, Publication No. L142, C.8. "Toxicity for earthworms".

A limit test was performed exposing forty earthworms (10 per replicate, 4 replicates) to an untreated control and 1000 mg SETAFIX Z1077/kg d.s. In addition, ten earthworms (1 replicate) per group were exposed to 1.0, 10 and 100 mg/kg d.s. in a range-finding test. Test duration was 14 days.

SETAFIX Z1077 did not cause mortality of Eisenia fetida fetida at 1000 mg/kg d.s. after 14 days of exposure (NOEC).

The 14-day LC50was beyond the range tested; i.e. exceeded a concentration of 1000 mg/kg d.s.

The 14-day EC50for body weight reduction was beyond the range tested; i.e. exceeded a concentration of 1000 mg/kg d.s.

As part of the information requirements as laid down in Section 9.4.2 Annex IX of the REACH Regulation the registrant proposes to investigate effects on soil microorganisms of the test substance, 1,6-Bis(methoxybenzoyloxy)hexane, with respect to the nitrogen transformation by soil microorganisms (EU Method C.21., Nitrogen transformation test). Moreover, a potential effect on the transformation of nitrogen by soil micro-organisms was indicated as a concern in the EU-Risk Assessment Report in 2001 and the test proposed addresses this concern.

As the information on this endpoint is not available for the registered substance but is needed in the technical dossier to meet the information requirements and, thus necessary to generate the data and to perform the test.
