Written question asked by Countess of Mar (Crossbench), in the House of Lords. It was answered by Earl Attlee (Conservative) on Thursday, 23 June 2011.

Aviation: Air Quality

Question: To ask Her Majesty’s Government what are the compositions of the triaryl phosphate additives used in the current fleets of commercial jet aircraft; which esterases, lipases, peptidases and other serine-active enzymes are inhibited by metabolites of triaryl phosphates; and which of these enzymes are important for neurological function and normal physiological health.

Answer: I refer the noble Countess to the Written Statement I made on 10 May 2011 (Official Report, cols. 37-38 WS). The information available has been published in the Cranfield University report. The next step is for the research studies which the department has commissioned to be referred to the Committee on Toxicity. This will be done once the last study—swab test research—has been completed by the Institute of Occupational Medicine in Edinburgh.
