| Fuel dumping is apparently reported to the Civil Aviation Authority (and is supposed to be done over the sea whenever possible) but apparently we can't be given the information about it ! https://www.whatdotheyknow.com/request/570355/response/1363831/attach/html/3/20190510Reply.pdf.html I'd agree with Raymond that it is rare - but on occasions I do find a pervasive "Heathrow odour" of kerosene when I open my front door in Isleworth and find it hard to believe that it is all coming from Heathrow , blown on the wind. In Holland, the people around Schiphol airport are increasingly concerned about the tonnage of carcinogenic benzene that is discharged to the atmosphere and query that industrial plants doing it would be heavily regulated. Jet engines are apparently pretty bad at complete combustion of the fuel when ticking over at low thrust levels when taxiing and the unburnt kerosene contains a small percentage of benzene. But a lot of planes and a lot of kerosene adds up to an appreciable discharge. |
