Driven by the global popularity of electric vehicles and the shortage of critical raw materials for batteries, the spent lithium-ion power battery (LIPB) recycling industry has exhibited explosive growth in both quantity and scale. However, relatively little information is known about the environmental risks posed by LIPB recycling, in particular with regards to perfluoroalkyl and polyfluoroalkyl substances (PFAS). In this work, suspect screening and nontarget analysis were carried out to characterize PFAS in soil, dust, water and sediment from a LIPB recycling area. Twenty-five PFAS from nine classes were identified at confidence level 3 or above, including 13 legacy and 12 emerging PFAS, as well as two ultrashort-chain PFAS. Based on the target analysis of 16 PFAS, at least nine were detected in each environmental sample, indicating their widespread presence in a LIPB recycling area. Perfluorodecanoic acid, perfluorooctanesulfonic acid and trifluoromethanesulfonamide showed significant differences in the four phenotypic parameters (growth, movement, survival and fecundity) of and were the most toxic substances in all target PFAS at an exposure concentration of 200 μM. Our project provides first-hand information on the existence and environmental risk of PFAS, facilitating the formulation of regulations and green development of the LIPB recycling industry.
受全球电动汽车普及和电池关键原材料短缺的推动，废旧锂离子动力电池（LIPB）回收行业在数量和规模上都呈现出爆发式增长。然而，对于 LIPB 回收所带来的环境风险，特别是全氟烷基和多氟烷基物质（PFAS）方面，人们知之甚少。在这项工作中，采用可疑筛选和非靶向分析方法，对 LIPB 回收区的土壤、灰尘、水和沉积物中的 PFAS 进行了特征描述。在置信水平 3 或以上，共鉴定出 25 种来自 9 类的 PFAS，包括 13 种传统 PFAS 和 12 种新兴 PFAS，以及 2 种超短链 PFAS。基于对 16 种 PFAS 的目标分析，每种环境样本中至少检测到 9 种 PFAS，表明它们在 LIPB 回收区广泛存在。全氟癸酸、全氟辛烷磺酸和三氟甲磺酰胺在 、的四个表型参数（生长、运动、存活和繁殖力）中表现出显著差异，并且在所有目标 PFAS 中，在 200 μM 的暴露浓度下，是毒性最大的物质。我们的项目提供了关于 PFAS 的存在和环境风险的第一手信息，有助于制定法规和促进 LIPB 回收行业的绿色发展。
