Quantitative evaluation method for peanut aflatoxin B1 pollution on human health risk

Abstract

The invention relates to a quantitative evaluation method for peanut aflatoxin B1 pollution on human health risk. The quantitative evaluation method comprises the following steps of: 1, sorting to obtain a peanut aflatoxin B1 pollution data distribution set which accords with sample data distribution characteristics; 2, dividing area populations to be evaluated according to corresponding population characteristics according to the evaluation needs, and integrating the corresponding data of the divided population for later use, wherein the data are used for subsequent evaluation; 3, establishing an evaluation model of the peanut aflatoxin B1 pollution exposed quantity of the population and an evaluation model of primary liver cancer excess case numbers caused by intake of peanut aflatoxin B1; and 4, integrating to obtain an evaluation result of the peanut aflatoxin B1 pollution on the human health risk, wherein the evaluation result comprises a variable evaluation result and an uncertain evaluation result. The evaluation method is used for quantitatively evaluating the peanut aflatoxin B1 pollution on the human health risk, is scientific and accurate in evaluation result and can provide key technology and data support for risk management implementation of the government, enterprises and the like.

Description

technical field [0001] The invention relates to the technical field of agricultural product and food quality safety evaluation, in particular to peanut aflatoxin B in the agricultural product and food quality safety risk evaluation technology 1 Methods for the quantitative assessment of pollution risks to human health. Background technique [0002] Peanut is an oil and economic crop widely cultivated in the world, and it is one of the four most important oil crops in the world. At the same time, it is also my country's main oil crop and agricultural product with pure export advantages. Its total output ranks first in China's oil crops. Therefore, peanuts occupy an important position in my country's agricultural development and export earnings. [0003] Aflatoxins are mainly biologically active secondary metabolites produced by fungi such as Aspergillus flavus, Aspergillus parasiticus and Aspergillus tererus, mainly including aflatoxin B 1 , Aflatoxin B 2 , Aflatoxin G 1...

AI Technical Summary

Problems solved by technology

Although this method is relatively simple and easy to operate, and the economic cost is low, the evaluation results are too rough and conservative, and the uncertainty and variability of the evaluation model cannot be analyzed, and it cannot reflect the differences in the distribution of chemical pollutants in the population and food.

And because the point assessment method assumes a single exposure scenario, it cannot provide sufficient information for decision makers to make reasonable and realistic judgments, resulting in the inability to achieve low-cost, high-efficiency, and highly operable emergency response to chemical pollutants. effectively avoid or reduce human health risks
