| 中文摘要: |
| 为了解国内外有关重金属生物可给性研究领域的主题演进、研究现状、研究进展及发展态势，本文通过检索2006—2018年共13年CNKI与Web of ScienceTM核心合集数据库中有关重金属生物可给性的文献，利用CiteSpace软件绘制关于重金属生物可给性研究的知识图谱，并进行文献可视化分析。结果表明：近13年来本研究领域中英文发文数量呈波动式增长态势，且在2011年和2016年的发文数量出现小高峰。国际重金属生物可给性研究可分为3个发展阶段，各个阶段研究热点不同，当前研究热点为“土壤性质、大气灰尘、食物链、PM2.5”；国内重金属生物可给性研究主题集聚成2个阶段及2条演化路径，其中2006—2014年为第一阶段，主要研究路径为“重金属-化学形态/体外消化法-生物有效性/生物可给性-健康风险评价”；2015—2018年为第二阶段，主要研究路径为“农田土壤-钝化剂（羟基磷灰石、过磷酸钙、腐植酸钾等）-体外消化模型-健康风险评价”，且第二阶段已受到广泛关注。健康风险研究由单一环境介质、单一风险受体、小尺度的评价演化为多种风险源、食物链、大尺度的综合评价。欧美国家奠定了重金属生物可给性的研究基础，中国起步较晚但发展迅速。 |

| In order to understand the evolution, current status, and progress of research related to the bioaccessibility of heavy metals, in addition to the development of their trends in China and abroad, this study searched relevant literatures from the database of CNKI(China National Knowledge Infrastructure) and Web of ScienceTM Core Collection Database for the period of 2006-2018. CiteSpace software was used to draw a knowledge map of the bioaccessibility of heavy metals and to make a visual analysis of relevant literatures. The results showed the following. The number of Chinese and English publications on the topic experienced a fluctuating, increasing trend between 2006-2018, with a small peak in the number of publications occurring in 2011 and 2016. International research on the bioaccessibility of heavy metals could be divided into three development stages, whereby the research hotspots of each stage were different. The keywords soil properties, atmospheric dust, food chain, and PM2.5 were the current research hotspots. Domestic research was clustered into two stages and two core evolution routes. The first stage of the main research route during the period from 2006-2014 was:heavy metals; chemical speciation/in vitro digestion; bioavailability/bioaccessibility; health risk assessment. The second stage of the main research route during the period from 2015-2018 was:farmland soil; passivation agent(e.g., hydroxyapatite, superphosphate, and potassium humate); in vitro digestion model; health risk assessment. This second stage had received extensive attention. The evaluation of health risk research had evolved from single environmental media, single risk receptor, and small-scale assessment to multiple risk sources, food chain, and large-scale comprehensive assessment. European and American countries laid the foundation for research in this field. China started late but had developed rapidly. |
