Prediction of heavy metal toxicity of terrestrial plants using biotic ligand model

Abstract

In the evaluation of soil contamination, the need for comprehensive hazard assessment by applying ecotoxicity tests has been recognized. The evaluation method of soil contamination by the terrestrial plant growth test was outlined. The terrestrial biotic ligand model used to predict the toxicity to the soil ecosystem was introduced in this manuscript, in addition to the introduction of soil contamination by conventional instrumental analysis. By combining a model that predicts the behavior of contaminants such as heavy metals in soil layers and groundwater with a model that can express combined toxicity caused by heavy metal mixture, it is expected that it will be possible to predict the state of the environment and the hazards to the ecosystem.
