概括

在法国11%的水资源中发现了2,6-dinitrotoluene (2,6-DNT) 和RDX等爆炸残留物,主要与历史军事遗址有关. 降解产品在饮用水中更常见,这表明持续存在的污染问题.

科学领域:

环境化学环境化学
分析化学分析化学
水资源管理水资源管理

背景情况:

历史上的军事活动对水质造成了持续的威胁.
了解爆炸物残留物的流行和来源对于公共卫生至关重要.
法国包括海外领土在内的水资源需要全面的污染评估.

研究的目的:

对法国水资源和饮用水中的爆炸物残留物及其降解产品进行全国性评估.
识别经常检测到的爆炸性化合物及其潜在来源.
评估与历史军事活动有关的这些污染物的存在.

主要方法:

使用高性能液体染色学-双重质谱法 (HPLC-MS/MS) 和气体染色学-双重质谱法 (GC-MS/MS) 分析了54种目标爆炸性化合物.
在2020年至2022年期间,从法国各地近300个地点采样样本,代表人口的20-25%,在2020年至2022年之间.
统计分析以确定污染物和潜在来源之间的相关性.

主要成果:

在797个水样中的11%中检测到爆炸物残留物,主要是在原始地下水中.
经常检测到的化合物包括2,6-丁二二烯 (2,6-DNT),二胺 (DPA) 和六-1,3,5-三-1,3,5-三 (RDX).
污染在很大程度上与历史战场和前弹药储存区有关,特别是在大东地区.

结论:

历史军事活动仍然是法国水污染的重要来源.
爆炸物的降解产品存在于饮用水中,这表明在处理过程中不完全去除.
持续监测水资源中的爆炸物残留物是必不可少的,特别是在具有军事历史的地区.

关键词:

Types of Toxins

Types of Toxins

Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.
Environmental pollutants like...

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...

Comparative Excretory Systems

Comparative Excretory Systems

Animals have evolved different strategies for excretion, the removal of waste from the body. Most waste must be dissolved in water to be excreted, so an animal’s excretory strategy directly affects its water balance.
