全氟烷基物质和多氟烷基物质(全氟烷基物质)因其非常高的持久性和对人类和环境健康的影响而受到关注。目前，许多不同的全氟辛烷磺酸(大约几千种)被广泛使用，没有关于许多单独物质及其在不同应用中的功能的全面信息来源。在这里，我们提供了对许多用途类别的广泛概述，其中使用了全氟化肥，以及用于哪些功能；我们还具体说明了使用了哪些全氟化肥，并讨论了用途的大小。我们的汇编并不详尽，但仍有可能证明，几乎所有的行业分支和许多消费产品都使用了全氟辛烷磺酸。总共为1400多个单独的全氟辛烷磺酸确定了200多个使用类别和子类别。确定的用途类别包括许多以前没有在科学文献中描述的类别，但也包括许多众所周知的类别，如纺织品浸渍、消防泡沫和电镀。除了对使用类别的详细说明外，本研究还包含按使用类别确定的全氟辛烷磺酸清单。在此基础上，提供了1400个全氟辛烷磺酸的准确质量数据库，以便于今后对更多的全氟辛烷磺酸进行分析检测。
Per- and polyfluoroalkyl substances (PFAS) are of concern because of their very high persistence and impacts on human and environmental health. Currently, many different PFAS (on the order of several thousands) are used in a wide range of applications and there is no comprehensive source of information on the many individual substances and their functions in different applications. Here we provide a broad overview of many use categories where PFAS have been employed and for which function; we also specify which PFAS have been used and discuss the magnitude of the uses. Our compilation is not exhaustive, but it was still possible to demonstrate that PFAS are used in almost all industry branches and many consumer products. In total, more than 200 use categories and subcategories were identified for more than 1400 individual PFAS. The identified use categories include many categories not previously described in the scientific literature but also a lot of well-known categories such as textile impregnation, fire-fighting foam, and electroplating. Besides a detailed description of use categories, the present study also contains a list of the identified PFAS per use category. On this basis, a database of exact masses of 1400 PFAS is provided that is intended to facilitate the analytical detection of many more individual PFAS in the future.
