Expert opinions on the essential use concept from the ZeroPM Prevention Workshop, Feb, 2023

Social science methods are not only useful to understand the public, they can also be used to better understand expert perspectives. We illustrate the views of 46 PFAS experts from recent a ZeroPM (Zero Pollution of Persistent, Mobile Substances; https://zeropm.eu) workshop on methods to prevent PFAS pollution[1]. Following a detailed literature review and discussion with key experts in the ZeroPM project we developed a short survey that experts could complete during the workshop. Workshop participants included members of the ZeroPM consortium, and individuals from the wider academic, political and industry fields.

[1] Average EUC ratings (SD) were collected from the ZeroPM Prevention Workshop held in Gothenburg, Sweden in February, 2023 (Male = 20; Female = 19; Prefer not to say = 7). The majority of these experts reported belonging to purely the Academic sector (N = 20), while the rest came from Regulation, the Water sector, the Chemical sector, NGOs or Other backgrounds.

社会科学方法不仅可用于洞悉公众认知，亦能助力更深入地把握专家视角。本研究展示了近期举办的ZeroPM（零持久性移动物质污染，Zero Pollution of Persistent, Mobile Substances；官网：https://zeropm.eu）研讨会中46位全氟/多氟烷基物质（PFAS，Per- and Polyfluoroalkyl Substances）专家的观点，该研讨会围绕PFAS污染防控方法展开[1]。本研究通过全面的文献综述，并与ZeroPM项目的核心专家开展研讨，最终设计了一份简短问卷，供参会专家在研讨会期间填写完成。本次研讨会的参会者涵盖ZeroPM联盟成员，以及来自更广泛的学术、政策与产业领域的人员。

[1] 本次收集的EUC平均分（标准差，Standard Deviation，SD）来自2023年2月于瑞典哥德堡举办的ZeroPM污染防控研讨会，参会者性别分布为男性20人、女性19人，另有7人不愿透露性别。其中多数专家仅隶属于学术领域（N=20），其余专家则来自监管、水务、化工、非政府组织或其他背景领域。
