Embodiment

[0018] Taking Mingshan District as an example, a rural drinking water safety and health risk assessment and management method, such as figure 1 and figure 2 As shown, it mainly includes the following aspects:

[0019] (1) Clarify the connotation and extension of drinking water risk and drinking water risk management in the broad sense and narrow sense, improve the calculation method of drinking water health risk assessment, the evaluation results are closer to the actual situation, establish the drinking water health risk assessment index system, and further clarify The specific content of the health risk assessment;

[0020] (2) Based on the existing water quality standards and chemical toxicity standards, establish a screening method for drinking water health risk hazards, and divide the compounds detected in the water quality of drinking water sources in Mingshan District into three categories based on factors such as content and toxicity to the human body , screened out...

Abstract

The invention relates to a country drinking water health risk assessment and management method and belongs to intersection of disciplines including science of environmental health, hydrology, science of water resources and the like. According to the country drinking water health risk assessment and management method, based on the four-step health risk assessment method (harm identification, dosage-reaction relation assessment, exposure assessment and risk characterization) of the National Academy of Science (NAS), human health hazards which may be caused by hazardous materials in a country drinking water source are assessed, the time distribution condition and the space distribution condition of the human health risk degree are analyzed based on the GIS technology, a visual geographic information management platform for country drinking water health risk assessment and management is also established, and therefore a scientific decision basis can be effectively provided for drinking water health risk control.

Description

technical field [0001] The invention relates to a rural drinking water health risk assessment and management method, which belongs to the technical field of hydrology and water resources. Background technique [0002] In recent years, with the continuous development of social economy and population increase, problems such as water environment pollution and water resource shortage have become increasingly serious, and threats to drinking water safety have continued to increase. The safety of drinking water in rural areas has always been an important factor that plagues China's economic development, and it is also a livelihood issue that leaders at all levels have worked hard to solve since the founding of New China. The quality of drinking water in rural areas has seriously affected human health and rural stability. It is one of the most concerned and urgent issues that people need to solve. Although traditional drinking water quality evaluation methods and standards can obj...
