概括

一种新的超分子溶剂 (SUPRAS) 提取方法在全球范围内确定了自来水中的33种新出现的污染物 (EC). 这种广泛的查突出了人类潜在的暴露风险,尽管初步评估显示健康风险较低.

科学领域:

环境化学环境化学
分析化学分析化学
公共卫生公共卫生

背景情况:

新出现的污染物 (ECs) 越来越多地出现在饮用水中,这是由于传统处理方法的不完全去除.
目前的监测方法范围有限,可能缺少未知的或不受监管的EC.
长期暴露于ECs对人类健康构成潜在风险,需要全面监测.

研究的目的:

开发和验证一种全面的方法,用于识别自来水中广泛的EC.
评估来自不同国际地点的饮用水样本中ECs的流行率.
评估与检测到的EC相关的潜在人类健康风险.

主要方法:

基于利用的超分子溶剂 (SUPRAS) 的全合一提取用于样品制备.
采用液体染色学高分辨率质谱法 (LC-HRMS) 进行疑似查分析.
分析了来自12个国家的53个饮用水样本.

主要成果:

暂时确定了33个EC,其信任级别为1-3,跨越广泛的极性范围 (日志P -1.3至16.2).
许多已识别的EC,包括个人护理产品,表面活性剂和塑化剂,首次在饮用水中报告.
初步风险评估表明,人类健康风险估计 (HQ和HI) 低于令人担忧的值.

结论:

基于SUPRAS的提取对于水中的各种EC的广泛选是有效的.
扩大超出目标污染物的监测对于全面了解水质至关重要.
龙头水可能是人类暴露于各种EC的来源,因此需要继续评估.

Precipitation and Co-precipitation

Precipitation and Co-precipitation

Precipitation and coprecipitation methods can be used to separate a mixture of ions in a solution. In qualitative inorganic analysis, ions that form sparingly soluble precipitates with the same reagent are separated based on the differences in solubility products. For example, consider the separation of Cu(II) and Fe(II) ions by precipitation as insoluble sulfides. First, copper(II) sulfide is precipitated by the addition of acidic H2S, where the dissociation of H2S is suppressed. Adding H2S...
