概括

在德国饮用水中检测到和多基物质 (PFAS),其总度低于监管限制. 然而,两个样本超过了特定PFAS的限值,表明了潜在的局部污染风险.

科学领域:

环境化学环境化学
分析水质分析水质
公共卫生公共卫生

背景情况:

和多基基物质 (PFAS) 是普遍存在的环境污染物,影响水循环.
关于德国饮用水源中PFAS的发生情况存在重大知识差距.
PFAS对饮用水质量和人类健康构成风险.

研究的目的:

评估26种PFAS在德国饮用水样本中的存在和度.
为了解决有关德国饮用水中PFAS污染的知识差距.
为了将检测到的PFAS水平与当前的监管限制进行比较.

主要方法:

收集了来自德国各个地区的89个饮用水样本.
使用高性能液体染色学与双重质谱学 (HPLC-MS/MS) 分析了26种PFAS.
对20个受监管的PFAS (PFAS20) 和6个额外的PFAS进行了有针对性的量化.

主要成果:

所有样本的PFAS20都低于0.1μg/L的极限,其度高达80.2 ng/L.
两个样本超过了四个关键 PFAS (PFHxS,PFOS,PFOA,PFNA) 的总和的20 ng/L限制.
perfluorooctanesulfonate (PFOS) 和 perfluorobutanesulfonate 是最常被检测到的单个 PFAS. 这些 PFAS 是最常被检测到的单个 PFAS.

结论:

虽然总体监管的PFAS水平低于限值,但局部超过特定的PFAS需要注意.
没有观察到明显的区域污染模式,但城市化地区的污染水平更高.
新型替代PFAS的度明显低于受监管PFAS的度.

Microbial Bioremediation of Pesticides

Pesticides often feature structurally complex chemical architectures, incorporating halogen groups and multiple aromatic rings. These characteristics confer high chemical stability, rendering many pesticides resistant to natural degradation processes. This resistance poses significant environmental concerns, as persistent pesticide residues can accumulate in ecosystems and affect non-target organisms.Despite the inherent stability of many pesticides, certain microorganisms possess the metabolic...
