Thumbs down CAA 2004 Cabin Air Quality paper

'Dolly with Brains' I agree, but its not just BRE than cannot be trusted, the CAA are as guilty as sin for their part in the cover up and failure to protect the crews and passengers.

The CAA in their 2004 Cabin Air Quality paper states in section 3.5.2 of their report...

“3.5.2 The occupational exposure limit for tricresylphosphate should be interpreted in the light of the ortho isomer of tricresyl phosphate (TOCP) being the most toxic and the meta and para isomers being listed as relatively non-toxic.”

Tricresylphosphate (TCP) is a generic name for 10 structurally similar isomers. TOCP is one of the isomers that makes up TCP but not the most toxic. MOCP and DOCP are more toxic isomers and present in engine oils at considerably higher levels than TOCP.

Amazingly the CAA paper fails to mention the existence of these more toxic isomers anywhere in their paper. Poor research or cover up?
