Description of key information
Additional information
The overall environmental fate profile indicates that the substance 2,6-dibromo-4-cyanophenyl octanoate will not persist in the environment.
The substance is hydrolytically degraded at 25 °C with a half-life of 1.7 days at pH 9, 11.5 days at pH 7 and 34.1 days at pH 5 (5.7, 38.3 and 113.5 days, recalculated to 12 °C).
Exposed to artificial sunlight, the substance is photolytically degraded in air with a half-life of 40 h, in aqueous solution with a half-life ranging from 5.2 hours to 16.7 days and in soil with a half-life of 2.2 2.6 days.
A study on the ready biodegradability found that the substance cannot be considered to be readily biodegradable according to OECD criteria.
Aerobic biodegradation of the substance was investigated in a simulation study with different water/sediment in aquatic model ecosystems at 20 °C. The formation of 14CO2 after 100 days accounted for 55.2 and 55.4%, respectively, of the applied radioactivity. The determined DT50 of the test compound ranged from <2 to 4 hours (4.2 to 8.5 hours, recalculated to 12 °C).
In three different soils, the target substance attained 29.4 – 55.1% degradation (elevation of 14CO2) after 35 days and 19.4 °C, and the half-life of the test substance in soil was found to range from 0.14 – 0.62 days (0.28 – 1.25 days, recalculated to 12 °C).
The log Koc was determined in five different soils and ranges from 3.94 – 4.51 which indicates a tendency to adsorb to soil. The log BCF for 2,6-dibromo-4-cyanophenyl octanoate was measured to be 2.26 (BCF= 180±40) for whole fish (Lepomis macrochirus), indicating a low potential for bioaccumulation.
The Henry’s Law Constant was calculated as 1.9E-1 Pa m³/mol (20 °C). The substance is thus not expected to evaporate from the water surface.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
