Comment on 'Comparative Assessment of the Global Fate and Transport Pathways of Long-Chain Perfluorocarboxylic Acids (PFCAs) and Perfluorocarboxylates (PFCs) Emitted from Direct Sources'

摘要

In their article, Armitage et al. apply the BETR Global multispecies mass balance model toward the fate and transport of C_8 through C_(13) perfluorinated carboxylic acids (PFCAs) (1). The authors acknowledge that "[t]he fate of PFC(A)s in the environment is determined by their partitioning properties and speciation... [k]ey environmental partitioning properties include... K_(aw)...K_(ow)...Ko_(oa)."
