概括

和多醇基物质 (PFAS) 是离子电池 (LIB) 生产中的新出现的污染物. 这项研究发现,LIB和传统行业对中国长江流域的PFAS污染作出了重大贡献,造成了生态风险.

科学领域:

环境化学环境化学
生态毒理学生态毒理学
工业污染监测工业污染监测

背景情况:

新兴的离子电池 (LIB) 产业释放出和多基物质 (PFAS),这是关键的新兴污染物.
对于LIB产业集群中PFAS的发生和生态风险的了解有限,特别是在中国的Yichun.

研究的目的:

调查23种PFAS在废水处理厂 (WWTP) 和长江流域内的河流中的分布,来源和生态风险.
与其他来源相比,阐明LIB行业对PFAS污染的贡献.

主要方法:

使用自组织地图 (SOM),正矩阵分解 (PMF),冗余分析 (RDA) 和风险系数 (RQ) 评估.
在废水处理厂的废水和接收河流 (金江和元河) 中分析了PFAS度.

主要成果:

总PFAS度在河流中平均为29.05 ng/L,在WWTP中为44.54 ng/L,其中短链PFAS占主导地位 (57.2%).
造成PFAS污染的主要原因是城市生活污水 (37.3%),传统工业 (31.4%) 和LIB行业 (31.3%).
perfluorooctane sulfonate (PFOS) 存在潜在的生态风险,估计每年流量为416.93公斤/年到Poyang湖.

结论:

LIB行业的增长与短链PFAS的增加相关,突显了无替代品和改进的WWTP的需求.
由于废物管理不充分,传统行业仍然是重要的PFAS来源,需要综合监管方法.
迫切需要全面的监管,以解决 PFAS 对长期水生生态系统健康的新兴和传统风险.

Acid Mine Drainage

Acid Mine Drainage

Mining activities that disturb sulfide-rich rocks, particularly those containing pyrite (FeS₂), initiate a cascade of geochemical and microbiological processes with serious environmental implications. When exposed to air and water, pyrite undergoes oxidation, releasing sulfate, ultimately forming sulfuric acid and mobilizing heavy metals into surrounding water systems. This phenomenon, known as acid mine drainage (AMD), results in low pH waters laden with toxic elements that threaten aquatic...

Bioplastics

Bioplastics

Bioplastics derived from microbial processes present a sustainable alternative to conventional petroleum-based plastics. Among these, polyhydroxyalkanoates (PHAs), particularly polyhydroxybutyrates (PHBs), have emerged as prominent candidates due to their biodegradability and biocompatibility. These polymers are synthesized by a variety of bacteria, such as Cupriavidus necator and Pseudomonas putida, which naturally accumulate PHAs as intracellular carbon and energy reserves, especially under...
