Embodiment Construction

[0115] The present invention will be further described below in conjunction with the accompanying drawings.

[0116] see figure 1 , soil heavy metal pollution risk assessment system for human health, including storage module, input module, heavy metal pollution risk assessment module, alarm module;

[0117] The storage module is managed by Microsoft SQL Server 2005 database, which is used to store the physical and chemical property parameters and toxicological data of various soil heavy metal pollutants, including CAS of chromium, cadmium, zinc, lead, mercury, arsenic, nickel and their compounds Number (Chemical Abstracts Service American Chemical Abstracts Service - registration number for chemical substances), molecular weight, density, vapor pressure, solubility, Henry constant, diffusion coefficient;

[0118] The input module is used to input the types of soil heavy metal pollutants, environmental concentrations and human health risk assessment parameters in the area to b...

Abstract

The invention relates to the technical field of environmental pollution evaluation, in particular to a risk assessment system of soil heavy metal pollution on human health, which can automatically assess the risk of the soil heavy metal pollution on the human health, save assessment time and improve assessment precision, and comprises a storage module, an input module and a heavy metal pollution risk evaluation module, wherein the storage module is used for storing parameters of physical and chemical properties and toxicological information of various soil heavy metal pollutants; the input module is used for inputting the types of the soil heavy metal pollutants of a region to be assessed, the ambient concentration and human health risk assessment parameters; and the heavy metal pollution risk evaluation module comprises a carcinogenic risk evaluation module, a non-carcinogenic risk evaluation module and a pollution risk level evaluation module, and is used for evaluating carcinogenic risk, non-carcinogenic risk and pollution risk level according to the types of the soil heavy metal pollutants, the ambient concentration and the human health risk assessment parameters.

Description

technical field [0001] The invention relates to the technical field of environmental pollution evaluation, in particular to a system for evaluating the risk of soil heavy metal pollution to human health. Background technique [0002] Soil is one of the main natural resources that human beings rely on for survival, and it is also an important part of the human ecological environment. With the intensification of industrial and urban pollution and the increase in the types and quantities of agricultural chemicals, soil heavy metal pollution is becoming more and more serious. Soil heavy metal pollution has the characteristics of poor mobility of pollutants in the soil, long residence time, and inability to be degraded by microorganisms, and can eventually affect human health through water, plants and other media. [0003] Soil heavy metal pollutants are mainly chromium, cadmium, zinc, lead, mercury, arsenic, nickel and their compounds. Soil heavy metal pollutants can enter the ...
