Additional information

Alkenes C24 - 28 do not contain any hydrolysable functional groups, so will not undergo hydrolysis. A biodgradation screening study is available with alkenes C24 - 28 which did not demonstrate ready biodegradability. A study with alpha olefins C26 - 28 also did not demonstrate ready biodegradability.

Log BCFs have been calculated on the basis of the calculated log Kow using a QSAR that is appropriate for icosene and docosene. These values have been read across to alkenes C24-28. The calculated log BCFs are 1.6 - 2.1. This indicates that alkenes C24-28 is not expected to pose a risk of bioaccumulation or secondary poisoning. A log Koc of >6.56 has also been read across from hexadecene.
