Risk assessment method and system based on target organ classification, and storage medium

A risk assessment, target organ technology, applied in urinary function assessment, nervous system assessment, instruments, etc., can solve the problem of classification of pollutants that do not solve the non-carcinogenic effect, and the non-carcinogenic risk level of soil and soil and the main target organs can not be obtained. Groundwater risk control value and other issues, to achieve the effect of improving the efficiency of risk assessment and reducing the cost of restoration

Problems solved by technology

[0004] Although the existing domestic and foreign risk assessment methods have many application examples in our country, they have not solved the problem of classifying pollutants that produce non-carcinogenic effects according to the main target organs, nor have they drawn the non-carcinogenic effects specific to the main target organs. Carcinogenic risk levels and soil and groundwater risk control values ​​based on non-carcinogenic risks

Embodiment 1

[0030] Embodiment one, as figure 1 As shown, a risk assessment method based on target organ classification includes the following steps:

[0031] S1: Obtain the one-to-one corresponding pollutant concentration data of each pollutant in the site;

[0032] S2: Compare each pollutant concentration data with the preset concentration screening value of the corresponding pollutant. The pollutants corresponding to the pollutant concentration data exceeding the preset concentration screening value are determined as pollutants of concern, and S3 is executed; if all the pollutant concentration data do not exceed the corresponding preset concentration screening value, it is determined that the site is risk-free;

[0033] S3: Obtain the target organ set corresponding to the concerned pollutant according to the non-carcinogenic effect of the concerned pollutant on the human body, and obtain the target organ toxicity dose set corresponding to the concerned pollutant according to the target...

Embodiment 2

[0192] Embodiment two, such as Figure 5 As shown, a risk assessment system based on target organ classification, including a data acquisition module, an initial assessment module, a risk characterization module, a reassessment module and a control value calculation module;

[0193] The data acquisition module is used to acquire the pollutant concentration data corresponding to each pollutant in the site;

[0194] The initial evaluation module is used to compare each pollutant concentration data with the preset concentration screening value of the corresponding pollutant, if there is any pollutant concentration data in all the pollutant concentration data that exceeds the preset value of the corresponding pollutant. Concentration screening value, the pollutant corresponding to the pollutant concentration data exceeding the preset concentration screening value is determined as the pollutant of concern; if all pollutant concentration data do not exceed the corresponding preset c...

Embodiment 3

[0199] Embodiment 3. Based on Embodiment 1 and Embodiment 2, this embodiment also discloses a risk assessment system based on target organ classification, including a processor, a memory, and a system stored in the memory and operable on the processor. A computer program on the computer program, when the computer program runs, it realizes as figure 1 The specific steps from S1 to S6 are shown.

[0200] The risk assessment of the present invention is realized through the computer program stored in the memory and run on the processor. Based on the target organ classification, it not only evaluates the non-carcinogenic risk level of the concerned pollutants to the human body through different exposure routes, but also Focusing on the harmful effects of pollutants specific to target organs, it can reflect in more detail the impact of various pollutants on human health in polluted sites; at the same time, based on the toxic dose of target organs, the set of risk control values ​​is...

Abstract

The invention relates to a risk assessment method and system based on target organ classification, and a storage medium. The method comprises the steps of obtaining pollutant concentration data of each pollutant; comparing each pollutant concentration data with a corresponding preset concentration screening value, and if the pollutant concentration data does not exceed the preset concentration screening value, determining that the site has no risk; if the pollutant concentration data exceeds the corresponding preset concentration screening value, determining the pollutant as a concerned pollutant, screening all concerned pollutants, and calculating a hazard index set corresponding to each concerned pollutant; performing risk assessment on the site according to the hazard index set of all the concerned pollutants, and if the assessment is passed, determining that the site has no risk; and if the evaluation is not passed, calculating a risk control value set of all the concerned pollutants according to the target organ toxicity dose set of all the concerned pollutants. The method is based on target organ classification, and reflects the harm condition of each pollutant to human health and the risk control value for repairing action in more detail.

Description

technical field [0001] The invention relates to the technical field of risk assessment of contaminated sites and environmental governance, in particular to a risk assessment method, system and storage medium based on target organ classification. Background technique [0002] Soil and groundwater are indispensable resources for economic and social development and people's life. With the development of economy and the acceleration of urbanization, the nature of land use is changing more and more frequently. In order to optimize the urban industrial structure and spatial layout, a large number of polluting enterprises have moved out of the city center, leaving behind a large number of polluted sites, and risk assessment is an important link in the process of site redevelopment and utilization after relocation. [0003] The risk assessment of contaminated sites mainly includes the following steps: hazard identification, exposure assessment, toxicity assessment, risk characteriza...
