  • Description: Because of concerns about their persistence and potential toxicity, certain per- and polyfluoroalkyl substances (PFAS) have been targeted for regulation or removal from commerce.1,2 Yet experts worry that regulations aimed at specific PFAS will lead to problems with “regrettable substitutions” in which a regulated chemical is replaced with an unregulated one that may be equally or even more toxic.1 In a commentary published in Environmental Health Perspectives, members of the Safer Consumer Products Program at the California Department of Toxic Substances Control (DTSC) elucidated the scientific rationale for a novel regulatory approach—regulating PFAS chemicals as a class.3 PFAS are a group of manmade chemicals that have been used widely over the past several decades in industrial applications, commercial household products, and food packaging.4 Numerous studies suggest that exposure to certain PFAS may be harmful to human health and the health of other organisms, although much remains to be learned.5 “There are six thousand or so PFAS chemicals,6 and the majority have not been thoroughly evaluated for ecological and human toxicity,” says André Algazi, senior study author and chief of the DTSC Chemical-Product Evaluation Section. Cousins and other environmental scientists have advocated for a persistence-sufficient, or “P-sufficient,” approach to regulating PFAS.7 The idea behind the P-sufficient approach is that the persistence of PFAS is a sufficient basis to warrant regulation regardless of, say, the chemicals’ bioaccumulation potential or toxicity.7 That is different from most chemical regulatory approaches, which tend to focus on hazard traits, such as whether a chemical is suspected or known to cause adverse health effects, Cousins explains. [...]the authors wrote that other chemical classes may lend themselves to the P-sufficient approach, including nonylphenol ethoxylates in laundry detergents and microplastics.3 Although many environmental scientists believe a P-sufficient approach is a step in the right direction when it comes to PFAS,7 it does not completely solve the problem of regrettable substitutions.
