全氟化合物(PFCs) | 持久性有机污染物的"顽疾"

来源：广州佳途科技股份有限公司分类：选购指南 2024-03-29 09:29:47 13阅读次数

全氟化合物 (PFCs) 是一种持久性有机污染物，具有神经毒性、肝脏毒性、胚胎毒性和致癌性等危害，已被列入《重点管控新污染物清单 (2023年版)》。

在食品安全领域，PFCs可从接触性材料(如食品包装材料等)中潜移默化地转移并残留于食品中，通过食物链进入人体。一旦摄入，这些化合物会在人体内富集，并可能引发一系列健康风险，如发育毒性、生殖毒性、肝肾毒性等。此外，PFCs的生物累积性还可能导致沿食物链逐级富集放大，最终危害整个生态系统。

PFCs在环境中表现出极高的持久性和广泛分布性。由于它们对热、光、水解等理化作用均极为稳定，在自然环境中几乎无法降解。因此，PFCs残留已成为大气、水体、土壤等环境介质中的"常客"。这些难降解物质还具有远距离迁移和跨界传递的能力，导致区域性和全球性污染。

PFCs也广泛应用于众多工业产品和消费品中，如纺织品防污涂层、食品加工助剂、化妆品防水剂等。无论使用过程中的残留，还是产品废弃后的释放，均可能导致PFCs进入环境。特别是，部分PFCs可通过皮肤吸收进入人体，对消费者健康构成潜在风险。

针对PFCs对人体健康和环境生态的多重威胁，《斯德哥尔摩公约》将部分长链PFCs列为新控制持久性有机污染物。减少其生产使用、寻找替代途径，并加强污染防控和环境修复，已成为全球性挑战。

通过对全氟化合物的测定，政府和监管机构可以制定更严格的规定和标准，以限制这些有害物质的使用和排放。CATO提供全氟化合物类检测标准品，支持全氟化合物污染的防治工作，助力推动更安全的消费品和工业实践的发展。
