Additional information
The biodegradability of the substance is tested in a CO2 Evolution Test according to OECD TG 301B and in compliance with GLP (Harlan, 2014). Test substance at a concentration of 5 mg/L (based on carbon) is inoculated 28 days with activated sewage sludge from an STP treating predominantly domestic sewage. During the 28 -day incubation period, carbon dioxide production is measured and biodegradation determined as % of ThCO2. After the 28-d incubation period, biodegradation is 0%. The reference substance sodium benzoate attained 84% biodegradation after 14 days and 90% biodegradation after 28 days thereby confirming the suitability of the inoculum and test conditions. The toxicity control attained 47% biodegradation after 14 days and 66% biodegradation after 28 days thereby confirming that the test item did not exhibit an inhibitory effect on the inoculum. Therefore, the substance is not readily biodegradable.
In a supporting study, the biodegradability of the substance was examined in a Manometric Respirometry Test according to OECD TG 301F and in compliance with GLP (Sinochem, 2013). The substance was added directly to the test vessels at a concentration of 36.6 mg/L (equivalent to 98.3 mg ThOD/L), and inoculated for 28 days with activated sludge from a domestic sewage. During inoculation the oxygen consumption was recorded and the biodegradation determined as % of the theoretical oxygen demand (ThOD).
The percentage biodegradation of test substance averaged 3.6% (n=2) after 28 days. Biodegradation of the reference substance attained 61.3% by Day 7, 78.3% by Day 14 and 87.1% by Day 28, thereby confirming the suitability of the inoculum and test conditions. In the toxicity control, 36.3% degradation occurred within 14 days. Since this value exceeded the 25% ThOD limit for (test item) toxicity, it was concluded that the test item was not inhibitory to sludge micro-organisms under the described conditions of this test. Therefore, the substance is not readily biodegradable.
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.
