基于植物重金属毒性的陆地生物配体模型(t-BLM)研究进展

陆地生物配体模型(t-BLM)是生物配体模型(BLM)理论在陆地生态系统中的应用,目的是通过量化土壤重金属形态、土壤基本性质以及生态毒理剂量-效应三者之间的关系,评价重金属对陆生生物的毒性。BLM已经成功地预测重金属对水生生物的毒性,但t-BLM的发展相对较为缓慢。基于植物重金属毒性综述了t-BLM近年来国内外的研究进展,介绍了t-BLM的原理、基于t-BLM的重金属(Cu、Ni、Zn、Cd等)的植物毒性及其影响因素,并且提出基于植物重金属毒性的t-BLM研究面临的主要挑战。

Review of the Terrestrial Biotic Ligand Model in Predicting Phytotoxicity of Heavy Metals in Soil

Terrestrial biotic ligand model (t-BLM) is the application of biotic ligand model (BLM) theory in terrestrial ecosystem, through the quantization of relationship between heavy metal speciation in soil, soil properties and ecological toxicology dose-response. It aims to evaluate the heavy metal toxicity effect to terrestrial organisms. BLM is successful in predicting the toxicity of heavy metals to aquatic organisms, however, the development of t-BLM is relatively slow. Based on the studies of the toxicity of heavy metal to plants, this paper reviewed the recent research progresses in t-BLM, and introduced the principles of t-BLM, the phytotoxicity of heavy metals (Cu, Ni, Zn, Cd, etc.) based on t-BLM and their influences. At the end of the paper, it presented the key challenges of this study.
