地下水资源作为一种最强大、最可靠的淡水资源,对维持饮用、保障工业和农业的供水安全具有重要意义。饮用水的安全关系到广大人民群众的身体健康、生命安全和社会的和谐稳定。然而,随着经济的迅猛发展,土地使用类型的改变以及人类活动的影响,地下水环境已经受到了污染和破坏。在当前水污染问题中,以有机物污染的矛盾最为突出,水中有机物对人体的影响也日益引起人们的关注。吹脱捕集-气质联用技术由于在方法前处理中不采用有机溶剂,属于绿色分析技术。它是一种动态顶空技术,减少了基体影响,增强了灵敏度,所以在测定挥发性有机物的过程中是首选方法。锦州市的典型区域涵盖了本市大部分的重点污染企业,沿着大小凌河扇地,在该区域进行地下水有机物污染方面的调查研究开展典型区域地下水有机物分析,对于保障饮水安全,是
As one of the most powerful and reliable freshwater resources, groundwater resources are of great importance to maintaining drinking water supply and ensuring the water supply security of industry and agriculture. The safety of drinking water has a bearing on the health and safety of the general public as well as the safety and social harmony and stability. However, with the rapid economic development, the change of land use types and the impact of human activities, the groundwater environment has been polluted and damaged. In the current water pollution problems, the contradiction between organic pollution is the most prominent, the impact of organic matter in water on the human body is also increasingly cause for concern. Stripping - GC-MS is a green analytical technique because no organic solvents are used in the pretreatment. It is a dynamic headspace technique that reduces matrix effects and enhances sensitivity, so it is the preferred method of determining volatile organic compounds. The typical area of Jinzhou covers most of the key polluting enterprises in this Municipality. The investigation of organic contaminants in groundwater along the small and medium-sized riverside spheres carries out the analysis of typical area groundwater organic matter. For the sake of ensuring drinking water safety,
