Abstract

To investigate the inter relationship of metal elements in soil-medicinal plant systems, 51 pairs of soil and Chinese herbaceous peony samples were collected from Bozhou City, China. Our results revealed that the major and trace elements in soils and Chinese herbaceous peony samples were in a similar descent order as: Al > Fe > Mn > Cr > Zn > Cu > Pb > As > Cd for soil samples, and Al > Fe > Zn > Mn > Cu > Cr > Pb > As > Cd for peony samples. The pollution indices of Enrichment factor (EF) and Nemerow integrated pollution index (NIPI) both indicated that Cr was the priority pollutant in soils and the other elements (Mn, As, Fe, Cd, Pb, Cu, and Zn) were slightly elevated. In general, the pollution load index (PLI) indicated that the studied soils were slightly contaminated by the nine elements. Furthermore, there existed significant relationship between Cr content in peony samples and Cr content in soils and soil pH (P < 0.01), indicating that the main source of Cr in Chinese herbaceous peony was probably from soils. Additionally, Cr content in peony samples displayed the highest hazard quotient (HQ) value, followed by As, Cu, Al, Fe, Zn, Mn, Cd, and Pb. Although the hazard quotient (HQ) for all elements and hazard index (HI) were lower than 1, which indicated no adverse health effects for adults, it was necessary to strengthen the control of soil Cr content in the process of peony planting.

土壤-药用植物系统中主要和微量元素的积累与健康风险——以亳州芍药为例

为了研究土壤-药用植物系统中金属元素的相互关系，从中国亳州市采集了51对土壤和芍药样品。结果表明，土壤和芍药样品中的主要元素和微量元素的下降顺序相似：土壤样品为Al>Fe>Mn>Cr>Zn>Cu>Pb>as>Cd，牡丹样品为Al>Fe>Zn>Mn>Cu>Cr>Pb>as>Cd。富集因子（EF）和Nemerow综合污染指数（NIPI）的污染指数均表明，Cr是土壤中的首要污染物，其他元素（Mn、As、Fe、Cd、Pb、Cu和Zn）略有升高。总的来说，污染负荷指数（PLI）表明所研究的土壤受这九种元素的轻度污染。此外，牡丹样品中铬含量与土壤中铬含量和土壤pH值之间存在显著关系（P<0.01），表明牡丹中铬的主要来源可能是土壤。此外，牡丹样品中Cr含量的危害商（HQ）值最高，其次是As、Cu、Al、Fe、Zn、Mn、Cd和Pb。尽管所有元素的危害商（HQ）和危害指数（HI）均低于1，表明对成人健康没有不良影响，但在牡丹种植过程中有必要加强对土壤Cr含量的控制。专题收藏：本文是与开采、研磨或天然金属矿床相关的地球化学过程的一部分，可在以下网站获取：https://www.lyellcollection.org/topic/collections/geochemical-processes-related-to-mined-milled-or-natural-metal-deposits

期刊介绍： Geochemistry: Exploration, Environment, Analysis (GEEA) is a co-owned journal of the Geological Society of London and the Association of Applied Geochemists (AAG). GEEA focuses on mineral exploration using geochemistry; related fields also covered include geoanalysis, the development of methods and techniques used to analyse geochemical materials such as rocks, soils, sediments, waters and vegetation, and environmental issues associated with mining and source apportionment. GEEA is well-known for its thematic sets on hot topics and regularly publishes papers from the biennial International Applied Geochemistry Symposium (IAGS). Papers that seek to integrate geological, geochemical and geophysical methods of exploration are particularly welcome, as are those that concern geochemical mapping and those that comprise case histories. Given the many links between exploration and environmental geochemistry, the journal encourages the exchange of concepts and data; in particular, to differentiate various sources of elements. GEEA publishes research articles; discussion papers; book reviews; editorial content and thematic sets.
