OECD SIDS N-(1,3-DIMETHYLBUTYL)-N´-PHENYL-1,4-PHENYLENEDIAMINE 3. ENVIRONMENTAL FATE AND PATHWAYS ID: 793-24-8 DATE: 11.05.2005 H3BO3 0.185 MnCl2 x 4H2O 0.415 ZnCl2 0.003 CoCl2 x 6H2O 0.0015 CuCl2 x 2H2O 0.00001 Na2MoO4 x 2H2O 0.007 The test solution (nutrient medium) and the head space were air saturated. Reliability : (2) valid with restrictions Comparable to guideline study with acceptable restrictions Flag : Critical study for SIDS endpoint 03.11.2004 (39) Type : Abiotic t1/2 pH4 : at °C t1/2 pH7 : = 3 - 4 hour(s) at 24 °C t1/2 pH9 : at °C Deg. product : Method : other: Monsanto Laboratory protocol; see test conditions Year : 1993 GLP : Yes Test substance : Remark : 6PPD is an antiozonant and as such necessarily reacts very quickly with oxygen. Therefore, fast oxidation in dilute solutions, where oxygen is readily available, is to be expected. The initial oxidation product is believed to be quinondiimine, which itself is a very reactive species. The quinondiimine can hydrolyze or form a polymer by further oxidation giving very complicated mixtures of products usually involving loss of the alkyl group. Test condition : Degradation in pH 7 buffered deionized water Reliability : (4) not assignable Original reference not available 10.08.2003 (40) 3.1.3 STABILITY IN SOIL 3.2.1 MONITORING DATA Type of measurement : concentration at contaminated site Media : Air Concentration : Method : GC/FID Method : The release of volatile rubber components from tyres during use was examined by GC/FID Result : During tyre use no emissions of volatile rubber components (including 6PPD) could be detected (Dannis 1975, cited according to BUA 1996) Reliability : (2) valid with restrictions Reliable source Flag : Critical study for SIDS endpoint 08.11.2004 (5) 3.2.2 FIELD STUDIES 64 UNEP PUBLICATIONS
