Soil eco-toxicology provides a theoretical basis for ecological risk assessment of contaminated soils and soil pollution control. Research on eco-toxicological effects and molecular mechanisms of toxic substances in soil environment is the central content of the soil eco-toxicology. Eco-toxicological diagnosis not only gathers all the information of soil pollution, but also provides the overall toxic effects of soil. Therefore, research on the eco-toxicological diagnosis of soil pollution has important theoretical and practical significance. Based on the research of eco-toxicological diagnosis of soil pollution, this paper introduced some common toxicological methods and indicators, with the advantages and disadvantages of various methods discussed. However, conventional biomarkers can only indicate the class of stress, but fail to explain the molecular mechanism of damage or response happened. Biomarkers and molecular diagnostic techniques, which are used to evaluate toxicity of contaminated soil, can explore deeply detoxification mechanisms of organisms under exogenous stress. In this paper, these biomarkers and techniques were introduced systematically, and the future research trends were prospected.
土壤生态毒理学为污染土壤的生态风险评估和土壤污染控制提供了理论依据。土壤环境中有毒物质的生态毒理效应及分子机制研究是土壤生态毒理学的核心内容。生态毒理诊断不仅收集了土壤污染的所有信息，还提供了土壤的整体毒性效应。因此，开展土壤污染的生态毒理诊断研究具有重要的理论和现实意义。基于土壤污染生态毒理诊断的研究，本文介绍了一些常见的毒理学方法和指标，并讨论了各种方法的优缺点。然而，传统生物标志物只能指示胁迫类型，无法解释损伤或响应发生的分子机制。用于评估污染土壤毒性的生物标志物和分子诊断技术，可以深入探究生物体在外源胁迫下的解毒机制。本文系统介绍了这些生物标志物和技术，并展望了未来的研究趋势。
