There is no question in my mind that fumes have affected my health.
Aside form the continuous flwo of the stuff in some airplanes, we are also getting the occasional major fumes event when the fumes pour onto the flight deck . Sometimes it's even detectable as a moist mist, especially after startup.
Organo phosphates aren't good for you, no doubt about it, but that's only one ingredient amongst dozens in this stuff which is bad for you.
