概括

和多基基物质 (PFAS) 是悉尼发现的持久污染物.

科学领域:

环境化学环境化学
分析水质分析水质
污染物监测污染物监测

背景情况:

和多醇基物质 (PFAS) 是广泛存在的持久性有机污染物.
全球饮用水供应日益受到PFAS污染的影响.
澳大利亚饮用水受到PFAS污染的研究仍然不足.

研究的目的:

调查悉尼饮用水中的PFAS的发生情况和概况.
在澳大利亚饮用水中识别以前未报告的PFAS化合物.
将PFAS水平与既定和拟议的饮用水准则进行比较.

主要方法:

从悉尼收集了32个自来水和12个瓶装水样本.
使用StrataX-AW弹进行固体相提取 (SPE) 进行样品预缩.
分析50个PFAS化合物,使用液体染色学-双重质谱法 (LC-MS/MS) 具有超微量检测极限.

主要成果:

在50个监测的PFAS化合物中,在悉尼饮用水中检测到31种.
在任何饮用水中首次检测到3:3 FTCA,在自来水中检测到6:2 diPAP.
在悉尼的自来水中检测到的21种PFAS以前没有在澳大利亚报告过;PFAS的配置文件从来源到自来水变化.
一些样本中的最大PFOS度达到或超过美国EPA指南,但仍低于澳大利亚2025指南.

结论:

这项研究显著扩大了对澳大利亚饮用水中PFAS存在的理解.
悉尼饮用水中的PFAS污染比以前知道的要多样化.
需要进一步的研究来评估澳大利亚环境中的PFAS来源,分布和持久性.

Quality of Water

Quality of Water

In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...
