Fluoroether distribution and spread from a fluorochemical manufacturer. Map of southeastern North Carolina with averaged PFECA and PFESA ToxPi profiles of pine needles collected from 14 locations in 2017–2018 (red outer circles) and 2019–2020 (blue outer circles). The factory icon signifies the location of the fluorochemical manufacturer, and the airplane icon points to the Fayetteville airport. 1 and 2 denote the sampling sites located approximately 1 and 2 miles from the fluorochemical manufacturing plant. The slices correspond to the labeled pie chart legend in both color and position.
