Final update on the human health assessment of long-chain chlorinated alkanes
On May 12, 2012 the Final Update on the Human Health Assessment of Long-Chain Chlorinated Alkanes was released and the related notice was published in the Canada Gazette, Part I: Vol. 146, No. 19 - May 12, 2012.
New information received after the publication of the 2008 final follow-up assessment report on chlorinated paraffins has led to a change in the conclusion previously published regarding chlorinated alkanes containing 18 carbon atoms or more.
The final update on the human health report concludes that chlorinated alkanes containing 18 or more carbon atoms are not entering the environment in a quantity or concentration or under conditions that may constitute a danger to human life or health as defined in the paragraph 64(c) of CEPA 1999.
Adding substances to Schedule 1
Chlorinated alkanes that have the molecular formula CnHxCl(2n+2–x) in which 10 ≤ n ≤ 20 have been added to Schedule 1.
Final order: Canada Gazette, Part II: Vol. 145, No. 21 – October 12, 2011.
Background
Chlorinated paraffins (CPs) were included on the first Priority Substances List (PSL1) under the 1988 CEPA for assessment of potential risks to the environment and human health.
