摘要

环三磷腈作为阻燃电解质添加剂在锂离子电池(LIBs)生产中得到了广泛应用。然而,它们的环境发生、行为和毒性作用尚未得到很好的探讨。本研究分析了在LIB制造园区周围收集的地表水和沉积物样本中的六种ctp。在地表水样品中检测到所有目标ctp,检测频率为10−90%。Phosphonitrilicchloridetrimer (HCCTP;55 ng/L)的平均水浓度最高,其次是乙氧基(五氟)环三磷腈(EPFCTP);29 ng/L)和六氟环三磷腈(hftp;24 ng / L)。沉积物中ctp的检测频率在19 ~ 95%之间。EPFCTP(平均24 ng/g dw)和六苯氧环三磷腈(HPCTP;20 ng/g dw)是沉积物中主要的ctp。平均log Koc值最高的是HPCTP(3.5±0.61),其次是磷腈氯三聚体(HCCTP;(3.2±0.69),EPFCTP(2.8±0.60),hftp(2.6±0.43)。此外,采用高通量表型筛选法评估ctp对秀丽隐杆线虫的毒性作用。靶CTP对秀丽隐杆线虫的4个表型参数(长度、运动、存活和繁殖力)均有不同的影响,在50 ~ 500 μM的暴露水平下,HCCTP是毒性最大的CTP。本研究为ctp的环境行为和毒性作用提供了第一个证据。这些发现对于制定策略以减轻锂离子电池制造过程中产生的ctp的释放和毒性影响至关重要。

Presence, partitioning, and toxicity of lithium-ion battery-derived cyclotriphosphazenes in aquatic environment

Presence, partitioning, and toxicity of lithium-ion battery-derived cyclotriphosphazenes in aquatic environment

Presence, partitioning, and toxicity of lithium-ion battery-derived cyclotriphosphazenes in aquatic environment
Cyclotriphosphazenes (CTPs) have been widely used as flame retardant electrolyte additives in the manufacturing of lithium-ion batteries (LIBs). However, their environmental occurrence, behaviors, and toxic effects have not been well explored. This study analyzed six CTPs in surface water and sediment samples collected surrounding a LIB manufacturing park. All target CTPs were detected in surface water samples, displaying the detection frequencies of 10–90 %. Phosphonitrilicchloridetrimer (HCCTP; 55 ng/L) exhibited the highest mean water concentration, followed by ethoxy(pentafluoro)cyclotriphosphazene (EPFCTP; 29 ng/L) and hexafluorocyclotriphosphazene (HFCTP; 24 ng/L). Detection frequencies of CTPs in sediment were in the range of 19–95 %. EPFCTP (mean 24 ng/g dw) and hexaphenoxycyclotriphosphazene (HPCTP; 20 ng/g dw) were the predominant CTPs in sediment. HPCTP (3.5 ± 0.61) displayed the highest mean log Koc value, which was followed by phosphonitrilicchloridetrimer (HCCTP; 3.2 ± 0.69), EPFCTP (2.8 ± 0.60), and HFCTP (2.6 ± 0.43). In addition, a high-throughput phenotypic screening assay was used to evaluate the toxic effects of CTPs on Caenorhabditis elegans. Target CTPs showed different effects on the four phenotypic parameters (i.e., length, movement, survival, and fecundity) of Caenorhabditis elegans, and HCCTP was the most toxic CTP at the exposure levels of 50–500 μM. To our awareness, this study provides the first evidence on the environmental behaviors and toxic effects of CTPs. These findings are critical for the development of strategies to mitigate the release and toxic impact of CTPs derived from the LIB manufacturing.

期刊介绍: Environmental Pollution is an international peer-reviewed journal that publishes high-quality research papers and review articles covering all aspects of environmental pollution and its impacts on ecosystems and human health. Subject areas include, but are not limited to: • Sources and occurrences of pollutants that are clearly defined and measured in environmental compartments, food and food-related items, and human bodies; • Interlinks between contaminant exposure and biological, ecological, and human health effects, including those of climate change; • Contaminants of emerging concerns (including but not limited to antibiotic resistant microorganisms or genes, microplastics/nanoplastics, electronic wastes, light, and noise) and/or their biological, ecological, or human health effects; • Laboratory and field studies on the remediation/mitigation of environmental pollution via new techniques and with clear links to biological, ecological, or human health effects; • Modeling of pollution processes, patterns, or trends that is of clear environmental and/or human health interest; • New techniques that measure and examine environmental occurrences, transport, behavior, and effects of pollutants within the environment or the laboratory, provided that they can be clearly used to address problems within regional or global environmental compartments.
