Do you think these chemicals are being transported next to most of us on the highway?

I can't tell you how many unmarked tanker trucks I see daily and wonder wtf is in there. Especially when they are marked as hazardous.

Would a spill of said chemicals on a roadway cause a serious problem?

Do they not bother using fluoride since it's already in the water?

If you had to guess. What is the tonnage a year that is sprayed?

Do you think passenger planes spray or is it strictly contracted out to others?
