Sir John Beddington, the Chief Scientific Adviser to HM Government and Head of Government Office for Science, has rejected calls to change the classification of chrysotile asbestos.
Sir John was asked to consider “whether there is any evidence that would justify an imminent change to the ‘international scientific consensus on the classification of asbestos’”.
In his findings, Sir John wrote that “it is not possible to determine a threshold level below which exposure to ‘pure’ chrysotile could be deemed ‘safe’ for human health. The same applies for exposure to chrysotile from cement during removal and disposal activities… Therefore it is my opinion that on the evidence available there is no justification for an imminent change to the international scientific consensus on the classification of chrysotile as a Class 1 carcinogen.”
Chrysotile, or white asbestos, is the most commonly encountered form of asbestos. It is currently banned for use in the European Union but was used extensively in the past, including in common building materials such as asbestos cement and Artex.
I welcome Sir John’s findings and am pleased to see that he is backing the international consensus that chrysotile is an extremely hazardous substance.
