What Are Some Examples of Regrettable Substitution?
Several well-documented cases exemplify regrettable substitution:
BPA Replacement: Bisphenol A (BPA) was replaced with bisphenol S (BPS) and bisphenol F (BPF) in many products. However, subsequent studies revealed that BPS and BPF might have similar or even worse endocrine-disrupting effects. Flame Retardants: The removal of polybrominated diphenyl ethers (PBDEs) led to the use of alternative flame retardants, such as organophosphates, which also pose health risks. PFAS Substitution: Long-chain per- and polyfluoroalkyl substances (PFAS) were replaced with shorter-chain versions. These were later found to be similarly persistent and potentially toxic.
