input. If the world input from military aircraft is triple this amount, then the world input is 3,000 tonnes. The sum total of aircraft dumping input is then estimated at 7,500 tonnes. It is estimated that 1/5 of these releases would take place over North American territorial waters on the basis of air traffic loading to and from North America, compared to the rest of the world. This again is subdivided by the approximate numbers of trans-ocean flights arriving/departing from airports in the designated regions (Tables 2-2 through 2-6).
