Key value for chemical safety assessment

Additional information

No studies on the toxicity to birds are available for the substance. In Annex X Section 9.6.1 of Regulation (EC) No 1907/2006, it is laid down that any need for testing should be carefully considered taking into account the large mammalian dataset that is usually available at this tonnage level. In case of the reaction product of 2,4-Dinitrotoluene and 2,6-Dinitrotoluene and hydrogen (EC 939-489-9) a mammalian dataset is available. In addition, the hazard assessment of the substance reveals neither a need to classify the substance as hazardous according to Regulation EC 1272/2008 and its second adaptation 286/2011, nor is it a PBT or vPvB substance, nor are there any further indications that the substance may be hazardous to the environment. Direct exposure is not intended based on the exposure assessment as the substance is not applied directly to soil. Based on the low log Kow and the low estimated BCF values, bioaccumulation in organisms is not to be expected (see IUCLID Ch. 5.3.1). Hence, secondary poisoning is of no concern. In Annex XI Section 3, it is laid down that testing in accordance with sections 8.6 and 8.7 of Annex VIII and in accordance with Annex IX may be omitted, based on the exposure scenario(s) developed in the Chemical Safety Report (“Substance-Tailored Exposure-Driven Testing”). In accordance with Annex XI Section 3, it can be demonstrated in the risk assessment that the manufacture and the use of the substance do not pose an unacceptable risk for all environmental compartments as the risk characterization ratios (RCRs) of the chemical safety assessment are below 1 for all compartments (see Chemical Safety Report Ch. 10). Therefore, and for reasons of animal welfare, no tests on birds are performed.
