Quote: Researchers are to travel on passenger and cargo flights to see if cabin air contamination is making travellers and pilots ill.
On most aircraft, pressurised air is pumped from the engines, before the combustion process, into the cabin. This is known as "bleed air" and, because it passes through the engine, the concern is that it is picking up substances such as engine oil.
There are particular concerns about two aircraft, the BAE 146 and the Boeing 757.
At the risk of sounding like a hypochondriac, I used to fly on the 146 / RJ100 on EDI-LCY a lot for work and on a few occasions we noticed the smell of jet fuel strongly in the cabin.
So, is there anything in this or is their media hype? Cough.

The Department for Transport is being heavily lobbied by a group of MPs that support a campaign from a group of ex airline pilots that claim their health has been severely damaged by fume events. The DfT have to show that they are investigating this 'percieved' problem.
Studies such as the European CabinAir project have shown that normally the levels of chemical and biological contaminants in aircraft are less than in many work environments such as office buildings.
There are however occasional bad smells or 'fume events' during flights, and these have been reported particularly on the Boeing 757, Airbus 319 and BAe 146.
The independent Committee on Toxicity has estimated that fume events occur on roughly 0.05% of flights overall (1 in 2000).
The most recent figures show that in 2007 there were 116 contaminated air events reported to the CAA mandatory reporting scheme (MORS) out of 1.3 million passenger and cargo flights by UK carriers. (Not all fume events are reported, but even if the number was doubled or tripled this would still be a very small proportion.)
Some pilots who have experienced these events report a variety of short or long term symptoms or ill health. But it is not certain that these symptoms are work related.
The independent Committee on Toxicity completed a substantial review of evidence in September 2007 and concluded that the evidence available did not establish a link between cabin air and pilot ill health, but nor did it rule one out.
