Atmospheric histories and growth trends of C 4 F 10 , C 5 F 12 , C 6 F 14 , C 7 F 16 and C 8 F 18 *

Abstract

Atmospheric observations and trends are presented for the high molecular weight perfluorocarbons (PFCs): decafluorobutane (C4F10), dodecafluoropentane (C5F12), tetradecafluorohexane (C6F14), hexadecafluoroheptane (C7F16) and octadecafluorooctane (C8F18). Their atmospheric histories are based on measurements of 36 Northern Hemisphere and 46 Southern… (More)
