The researchers detected up to 300,000 UFPs per cubic centimeter of air. This is more than 10 times the normal background level at the airport at night when no aircraft are operating. In cities, typical UFP measurements range from about 5,000 to 40,000 particles per cubic centimeter of air, significantly lower than the values measured at the airport. I think that’s the important bit, just how much more there is compared to “normal” pollution. Well, I just crossposted because I immediately thought of chemtrail memes.
