Soil metal toxicity prediction method and device, electronic equipment and storage medium

Abstract

The invention provides a soil metal toxicity prediction method and device, electronic equipment and a storage medium. The method comprises the steps of: firstly determining the dosage of each metal element in to-be-predicted soil according to the obtained physicochemical property parameters of the to-be-predicted soil and the total concentration of the metal elements; and then determining characteristic parameters of to-be-detected metal ions in the to-be-predicted soil, and predicting the metal toxicity effect of the to-be-predicted soil through a soil metal toxicity prediction model. Due to the adoption of the soil metal toxicity prediction model, the metal toxicity effects under different soil environment conditions can be accurately predicted while geometric number-level ecological toxicology tests are avoided. Meanwhile, due to the fact that establishment of the ecological risk and the restoration standard of the metal elements is relatively slow, the soil metal toxicity prediction model can predict unknown metal toxicity data, is suitable for soil environment conditions with a wide range, provides a basis for metal ecological risk evaluation and corresponding standard formulation, and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of ecological metal toxicity assessment, in particular to a soil metal toxicity prediction method, device, electronic equipment and storage medium. Background technique [0002] At present, heavy metal pollution is becoming more and more serious. Excessive heavy metals entering the soil environment not only destroy the physical and chemical properties of the soil, affect the production of plants, pollute crops, but also enter the human body through the food chain, and eventually endanger human health. Therefore, it is necessary to predict the toxicity of soil metals and then control the environment. Metal risk is critical. [0003] At present, when predicting soil metal toxicity, a biological ligand model (Biotic Ligand Model, BLM) is introduced. Although BLM can effectively predict the toxicity of soil metals, the types of elements it contains are very limited, and the relevant toxicity threshold has not y...

AI Technical Summary

Problems solved by technology

Although BLM can effectively predict the toxicity of soil metals, the types of elements it contains are very limited, and the relevant toxicity threshold has not yet been determined, so there is a large deviation when it is applied to the real soil environment, and it cannot be fully applied to the real soil environment.
