新型全氟化合物——全氟烷基磷酸对环境影响的研究综述

全氟烷基磷酸是一种新型全氟化表面活性剂,被广泛应用于匀染剂、湿润剂和农药中的消泡添加剂等。在美国,基于对其潜在毒性的考虑,美国环境保护总署已禁止全氟烷基磷酸在粮食作物农药中使用。从全氟烷基磷酸的注册使用情况、结构与环境行为、环境介质中的浓度水平和生物暴露毒性等方面分别展开论述,旨在为中国开展该类物质的环境研究提供可借鉴依据。

Review on Perfluorinatedphosphonic Acids A New Kind of Perfluorinated Chemicals

Perfluorinatedphosphonic acids （PFPAs） are new commercial surfactants used as leveling and wetting agents for wa xes and coatings and inert defoaming additives to pesticide formulations. The lack of available toxicity data and potential concerns a- bout persistence were contributing factors for the U.S. EPA to decide to no longer permit to use of these chemicals in food-use pesti cides. PFPAs are discussed in aspects of the registration and use situation, structure and environmental behavior, environmental lev els and exposure toxicity of based on recent literatures. This work aimed to provide a comprehensive understanding to provide basic background and data for environmental risk assessment in China.
