土壤—水稻镉生物有效性预测模型研究进展
Research Progresses on Prediction Models of Cadmium Bioavailability in Soil-Rice System
摘要
Abstract
The migration and transformation process of heavy metal cadmium (Cd) in soil-rice system is extremely complex and has many influencing factors.Accumulation of cadmium in rice may cause serious effects on human health, and the harm of cadmium in rice depends on the bioavailability of Cd.Therefore, using mathematical models to simulate and predict the bioavailability of cadmium in soil-rice system has become a hot topic of this field.The establishment of cadmium bioavailability prediction models in soil-rice system could provide an effective tool for environmental risk assessment, soil environmental quality standards and safety threshold of agricultural products, and also provide a reference for the production of safe rice.This paper reviewed the application range of three existing models including empirical (statistical) models, mechanism models and semi-mechanical models as well as their advantages and shortcomings, and also summarized the effects of soil types and properties on Cd accumulation of rice.At the same time, the limitations of the current mathematical models were discussed, suggesting that a more comprehensive and integrated mathematical models to simulate and predict the bioavailability of cadmium in soil-rice system with emphasis on interdisciplinary study will be the trend of the future development.关键词
