Question to the Department for Transport:

To ask the Secretary of State for Transport, with reference to the Answer of 5 March 2015 to Question 225928, what (a) recent discussions he has had and (b) discussions he plans to have with the Civil Aviation Authority on its work reviewing the evidence for the possibility of genetic factors which might influence individual susceptibility to environmental toxins.

The Department four published reports into cabin air were sent to the European Aviation Safety Agency (EASA) for their consideration. EASA are responsible for determining the requirement for and specification of any additional monitoring on board commercial aircraft.

I understand they have recently launched a Preliminary Cabin Air Measurement Campaign. This campaign will develop the methodology including equipment to be used, to perform cockpit and cabin air measurements. This will be followed by a large scale project of in-flight testing of cabin air quality.
