Administrative data
Link to relevant study record(s)
Description of key information
The parent substance is fully eliminated with molybdenum turning to molybdic acid and water soluble structurally modified substances were produced in addition.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
Key study:
In a biodegradation study conducted according to Japanese Guideline study on microbial degradation of chemical substances (MHLW/PFSB Notification No. 1121002 Nov 21, 2003, METI/MIB Notification No. 2 Nov 13 2003, and MOE/EPB Notification No. 031121002 last revised Nov 20, 2006) under GLP conditions, degradation of Molyvan 855 averaged 57% (based on BOD) and elimination was 98% (based on residual test substance) after 28 days in sludge. The parent substance is fully eliminated with molybdenum turning to molybdic acid. Structurally modified, water soluble substances also were produced. (Mitsubishi Chemical Medience Corporation, 2009).
Supporting study:
In a study conducted according to Japanese Guideline,Degree of Decomposition of Chemical Substances by Microorganisms, etc. in Test Methods for New Chemicals based on Kanhogyo No. 5, Yakuhatsu No. 615 and kikyoku No. 392 (1984), similar degradation rates were observed. Decomposition averaged 61% (based on BOD) after 28 days in sludge, although overall decomposition of two primary substance constituents averaged 92% (based on TOC) and 97% (based on HPLC). (Kagakuhin Kensa Kyokai Foundation, 1987).
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.
