You could do a check for heavy metals. Here are some links to companies that do this. The tests aren't cheap.

I did some checking and didn't find much to warrant concern from airport pollution directly from overhead flying. There have been some famous farms near airports in California and Europe.
Also, strong soil with high organic matter and high biological activity can decompose chemicals like fuel residues etc. if by, chance they are there. That organic activity is what we gardeners treasure for so many rains.
Hope this helps. Feel free to follow up with any questions through the Ask Extension system or directly to me at <personal data hidden>. Chip Bubl OSU Extension Agent/Columbia County (recently retired).
