摘要
介绍污染地块土壤铅风险评估工具,暴露吸收生物动力学模型(IEUBK模型)和成人血铅模型(ALM模型),概括叙述模型的结构、参数的定义与取值,介绍模型在国内的本土化应用案例,开展对模型涉及参数选取的探讨,最后针对模型的应用提出了存在问题与展望。目前,对于敏感人群暴露参数的研究存在数据积累不足,不确定性和偏差,国家层面上尚未发布污染地块土壤铅风险评估相关技术指导文件。研究可为污染地块土壤铅的风险评估工作提供参考。
This paper introduces the Integrated Exposure Uptake Biokinetic Model(IEUBK)and Adult Lead Model(ALM)for soil lead risk assessment tools in contaminated plots.The structure of the model,the meaning and value of the model parameters,the localized application cases of the model in China are described.The selection of parameters involved in the model is discussed.Finally,relevant problems and prospects for the application of the model are put forward.At present,there are insufficient data accumulation,uncertainty and bias in the research of exposure parameters of sensitive population.At the national level,the relevant technical guidance documents for the risk assessment of soil lead in contaminated plots have not been released,and this paper provides a reference for the risk assessment of soil lead in contaminated plots.
