Description of key information
The ready biodegradability of 4-methylthiosemicarbazide was evaluated in a study performed in accordance with OECD testing guideline 301 B and GLP requirements. According to the results obtained, 4-methylthiosemicarbazide is not considered as readily biodegradable (0% at day 28).
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
The ready biodegradability of 4-methylthiosemicarbazide was evaluated in a study performed in accordance with OECD testing guideline 301 B and GLP requirements.
The maximum level of biodegradation was 0 % in 28 days. Therefore, according to these results, 4-methylthiosemicarbazide is not considered as readily biodegradable.
In the test conditions, no inhibitory effect of 4-methylthiosemicarbazide on the micro-organisms of the inoculum was observed.
Validity criteria were fulfilled
