Additional information

Soil stability studies using the source substances L2 and L3 under test conditions relevant to this endpoint have demonstrated that the test substance is likely to be too volatile to maintain adequate concentrations in the test system. This is demonstrated by recoveries of the related substance L2 <LOQ by day 3 of the OECD TG 216 test (please refer to Section 6.3.4) and also very poor recoveries in a stability / recovery pre-test with the related substance L3 under conditions of OECD TG 222 (please refer to Section 6.3.1).As discussed in Section 6.0, M3T has very similar physicochemical and partitioning properties to L3, therefore testing in accordance with OECD TG 208 or similar guidelines to fulfil this REACH endpoint can be expected to show similar volatilisation losses, meaning that test organisms cannot be exposed to test material for long enough or at high enough concentrations to assess its toxicity. Testing of this endpoint is therefore waived because the study is technically not feasible.
