Concept information
PREFERRED TERM
deposition perfluorooctanesulfonic acid mass flux
DEFINITION
- Mass flux is defined as the amount of mass transported per unit time across a unit area that is perpendicular to the direction of mass transport. Deposition is the sum of dry deposition (uptake at the earth's surface) and wet deposition (absorption into droplets followed by droplet precipitation, e.g., rain, snow, sleet) or impaction on the earth's surface (e.g., fog droplets). The chmical formula for perfluorooctanesulfonic acid is C8HF17O3S. It belongs to the group of persitent organic pollutants (POPs) known as polyfluoroalkyl substances (PFAS). The IUPAC name is 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecafluorooctane-1-sulfonic acid
