Toxicity to soil macroorganisms except arthropods
Administrative data
- Endpoint:
- toxicity to soil macroorganisms except arthropods: long-term
- Type of information:
- experimental study planned
- Justification for type of information:
- TESTING PROPOSAL ON TERRESTRIAL INVERTEBRATES OECD 222
NON-CONFIDENTIAL NAME OF SUBSTANCE:
- Name of the substance on which testing is proposed to be carried out: ’Reaction mass of benzyl 2-ethylhexyl adipate and bis(2-ethylhexyl) adipate and dibenzyl adipate’ (EC No. 905-983-8).
CONSIDERATIONS THAT THE GENERAL ADAPTATION POSSIBILITIES OF ANNEX XI OF THE REACH REGULATION ARE NOT ADEQUATE TO GENERATE THE NECESSARY INFORMATION:
- Available GLP studies: For ’Reaction mass of benzyl 2-ethylhexyl adipate and bis(2-ethylhexyl) adipate and dibenzyl adipate’ (EC No. 905-983-8) no studies assessing the toxicity on terrestrial invertebrates are available yet.
- Available non-GLP studies: No further studies on terrestrial toxicity on invertebrates are available for ’Reaction mass of benzyl 2- ethylhexyl adipate and bis(2-ethylhexyl) adipate and dibenzyl adipate’(EC No. 905-983-8).
- (Q)SAR: There are no QSAR models available for this higher tier ecotoxicological endpoint that are sufficiently validated and acceptable (according to OECD Q/SAR validation criteria).
- Weight of evidence & Grouping and read-across: ’Reaction mass of benzyl 2- ethylhexyl adipate and bis(2-ethylhexyl) adipate and dibenzyl adipate’ (EC No. 905-983-8) is not part of a category and no data on terrestrial toxicity on invertebrates for ’Reaction mass of benzyl 2- ethylhexyl adipate and bis(2-ethylhexyl) adipate and dibenzyl adipate’ (EC No. 905-983-8) or related substances is available. There is thus no data supporting a weight of evidence or read-across approach and further testing is deemed necessary.
CONSIDERATIONS THAT THE SPECIFIC ADAPTATION POSSIBILITIES OF ANNEXES VI TO X (AND COLUMN 2 THEREOF) OF THE REACH REGULATION ARE NOT ADEQUATE TO GENERATE THE NECESSARY INFORMATION:
Recent experimental results from a chronic daphnia study (2021, according to OECD Guideline for the Testing of Chemicals, No. 211, "Daphnia magna, Reproduction Test) indicate chronic toxicity of ‘Reaction mass of benzyl 2-ethylhexyl adipate and bis(2-ethylhexyl) adipate and dibenzyl adipate’ (EC No. 905-983-8) towards aquatic invertebrates. Based on the determined NOEC (4.34 µg/L), the T criterion is fulfilled (NOEC ≤ 0.01 mg/L for marine/freshwater organisms) and there is indication that the registered substance is very toxic to aquatic organisms. In addition, the range of the calculated partition coefficient (logKOW between 4.80 and 8.12, individually calculated for the components) and the range of the adsorption coefficient (logKOC between 3.45 and 5.29, individually calculated for the components) are both indicative for a high adsorptive potential. Thus, based on the indications to be very toxic to aquatic organism and to be highly adsorptive, the registered substance is assigned to soil hazard category 4 as described in REACH Guidance document R7.c, Version 3.0 (June 2017). According to Table R.7.11-2 the screening assessment based on EPM is not recommended for substances assigned to hazard category 4. In order to derive the PNECsoil, and to assess the toxicity towards the terrestrial compartment, experimental studies are required. According to REACh Regulation (EC) No. 1907/2006, Annex IX, 9.4, column 2 and ECHA Guidance R.7c (2017), long-term studies are recommended for compounds with high potential for adsorption to soil. The registrant has carefully considered the available adaptation possibilities applicable for the discussed endpoint. Based on the lack of data on toxicity testing on terrestrial invertebrates and the recommendations in ECHA Guidance R.7c (2017), it is deemed necessary to further investigate the long-term toxicity potential of the substance.
FURTHER INFORMATION ON TESTING PROPOSAL IN ADDITION TO INFORMATION PROVIDED IN THE MATERIALS AND METHODS SECTION:
- The registrant intends to perform the long-term toxicity to terrestrial invertebrates according OECD TG 222 Earthworm Reproduction Test (Eisenia fetida/ Eisenia andrei). According the guideline, the study design of this study will fit to the physico-chemical properties of the test substance, as this study can deal with substances with low water solubility. With respect to the ready biodegradability of the test substance, concentrations need to be analysed before, during and at the end of the test (cf. OECD TG 222).
