Description of key information
In a study conducted according to the standard BOD technique (APHA (1980) and using three different inoculum sources (ground water, river water, and harbour water), acetophenone biodegradation and the corresponding half-lives were in the range between ca. 40 and 82% and 4 (harbor water), 8 d in river water, and 32 d (ground water), respectively. The authors assumed, that the observed high biodegradation rate of acetophenone using harbour water as inoculum may be due to the fertility and/or the presence of microorganisms that were pre-exposed to the test chemical or similar chemicals. In another study, the biodegradation of acetophenone was investigated using Ohio River water as inoculum. The biodegradability was followed by determination of carbon dioxide production. The test was conducted at pH 7.2+/-0.1 and temperatures in the range of 22-25°C. After 10 d samples were redosed to check possible acclimation. Initially, a lag phase of about three days was observed. Thereafter acetophenone was biodegraded relative quickly: ca. 50% degradation after 6 days based on CO2 production due to oxidation of test item and ThCO2 production. Redosing after 10 days resulted in rapid degradation: ca. 50% were degraded after 3 days.
Key value for chemical safety assessment
Additional information
Reliable results are available obtained from a study conducted according to national standard method and a study that meets generally accepted scientific principles and which are documented in sufficient details.
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.
