Written question asked by Countess of Mar (Crossbench), in the House of Lords. It was answered by Earl Attlee (Conservative) on Tuesday, 7 June 2011.

Aviation: Air Quality

Question: To ask Her Majesty’s Government what are the individual concentrations of the toxic isomers MOCP, DOCP and TOCP (mono-ortho-cresyl phosphate, di- and tri-) present in the tricresyl phosphate preparation specifically used in synthetic jet engine oils.

Answer: I refer the noble Countess to the Written Statement made on 10 May 2011 (Official Report, col. WS 37). The information available has been published in the Cranfield University report. The next step is for the research studies, which the Department for Transport has commissioned, to be referred to the Committee on Toxicity. This will be done once the final study—swab test research—has been completed by the Institute of Occupational Medicine in Edinburgh.
