含氟聚合物是全氟烷基和多氟烷基物质（PFAS）类别内的一组聚合物。本分析的目的是评价含氟聚合物在其整个生命周期中对环境和人类健康影响的证据。一些含氟聚合物的生产与传统和新型PFAS作为聚合物加工助剂的使用和排放密切相关。氟化加工助剂对人类和环境的毒性和不良影响令人严重关切。各种其他PFAS，包括单体和低聚物，在含氟聚合物的生产、加工、使用和报废处理过程中排放。人们还对含氟聚合物及其相关产品和物品在其生命周期结束时的安全处置表示关切。虽然对一些工业废物进行了含氟聚合物的回收和再利用，但从消费品中回收含氟聚合物的选择有限。本分析中审查的证据没有发现得出含氟聚合物对环境和人类健康影响较小的结论的科学依据。鉴于含氟聚合物具有极强的持久性，其生产、使用和处置过程中产生的排放以及人类接触全氟辛烷磺酸的可能性很高，因此，除必要用途外，应减少其生产和使用。
Fluoropolymers are a group of polymers within the class of per- and polyfluoroalkyl substances (PFAS). The objective of this analysis is to evaluate the evidence regarding the environmental and human health impacts of fluoropolymers throughout their life cycle(s). Production of some fluoropolymers is intimately linked to the use and emissions of legacy and novel PFAS as polymer processing aids. There are serious concerns regarding the toxicity and adverse effects of fluorinated processing aids on humans and the environment. A variety of other PFAS, including monomers and oligomers, are emitted during the production, processing, use and end-of-life treatment of fluoropolymers. There are further concerns regarding the safe disposal of fluoropolymers and their associated products and articles at the end of their life cycle. While recycling and reuse of fluoropolymers is performed on some industrial waste, there are only limited options for their recycling from consumer articles. The evidence reviewed in this analysis does not find a scientific rationale for concluding that fluoropolymers are of low concern for environmental and human health. Given fluoropolymers’ extreme persistence, emissions associated with their production, use, and disposal, and high likelihood for human exposure to PFAS, their production and uses should be curtailed except in cases of essential use.
