de Ree was only looking at TOCP, an isomer of TCP - TOCP is virtually not present in current synethetic jet engine oil formulations so mostly irrelvant to the debate. de Ree is not able to say levels present
'were below those that could cause the symptoms' as no other TCP isomer has an exposure standard. Also exposure standards when they do exist, do not apply to passengers - only workers, only relate to one compound, not a mixture (contaminated air exposure is an exposure to a complex mixture of chemicals) and they do not apply at altitude etc.. This was clarifed at the 2005 BALPA conference. The new blood test is not just proof of exposure to TCP but also looks at how much protein decoration has occurred.
