Concept information
PREFERRED TERM
deposition heptafluorobutyric 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 heptafluorobutyric acid is C4HF7O2. It belongs to the group of persitent organic pollutants (POPs) known as polyfluoroalkyl substances (PFAS). The IUPAC name is 2,2,3,3,4,4,4-heptafluorobutanoic acid
