Method for evaluating heavy metal pollution and potential ecological risks of agricultural land

Abstract

The invention relates to the technical field of agricultural land environment pollution evaluation, and particularly relates to a method for evaluating heavy metal pollution and potential ecological risks of agricultural land. The method comprises the following steps: firstly, performing sampling, then chemically measuring the content of heavy metals in soil, and on the basis of analyzing the pollution degree of agricultural land by adopting a land accumulation index method and an improved inner Meiluo comprehensive pollution index method, providing a set of new evaluation method for comprehensively considering the soil, the pollution space-time trend, the diagenetic effect, the influence of human activities on the environment and other aspects. According to the method, the limitation of atraditional potential ecological risk evaluation method is overcome; accuracy and scientificity of agricultural land heavy metal pollution risk evaluation are improved to a certain extent, ecologicalrisks of heavy metals in soil can be comprehensively and accurately evaluated, and substantial method guidance is provided for agricultural land heavy metal pollution monitoring, environmental management and ecological protection.

AI Technical Summary

Benefits of technology

This patented technical effect of our inventor's innovation relates to an effective way to estimate the amount of harmful materials (HAP) released from crops during their production process without being limited or subjected to external factors like weather conditions. By analyzing these indicators at specific time points within the crop field, we aim to identify those regions where HAP have higher concentration compared to others zones. These identified locations help us make informed decisions about managing future issues related to pesticides use. Overall, this technology helps prevent damage caused by excessive exposure to chemical fertilizers through monitoring its release rate and reducing associated economic losses.

Problems solved by technology

Technological Problem: Current Ground Heavy Metry (GHM) Index Method does not adequate address the issue of identifying specific areas with significant amounts of harmful elements present within large tractable regions due to their ability to affect both ground fertility and food supply. Existing assessment techniques have limitations in terms of precision and consistency across different locations where they were applied. Additionally, current EcoSense® Analysis Protocol provides technical indicators about the presence of certain substances at levels above threshold limits and potentially causes negative side reactions towards these contaminates.
