Description of key information

Alkenes C20-24 are not inhibitory to microrganisms

Key value for chemical safety assessment

Additional information

Two tests are available which investigated the inhibitory effect of alkenes C20 - 24 on activated sewage sludge. Both Mead (1998) and Clarke (2008) tested the toxicity of alkenes C20 - 24 in an OECD 209 test. No inhibition was observed at the single loading rate of 1000 mg/l in either test. Therefore the NOEC is 1000 mg/l.
