Abstract

Abstract:

To illustrate the role of Artemisia argyi in remediation of arsenic and other heavy metal contaminated soil, A. argyi collected from the vicinity of abandoned arsenic smelters in a non-ferrous metal mining area of Guangxi Province was used as the research object, the dominant populations of A. argyi and their root soil samples were collected from different sampling sites, and some physical and chemical indexes of the root soil and the heavy metal contents in the roots, stems and leaves of A. argyi were determined. The heavy metal accumulation and transport coefficients in different parts of A. argyi were compared and analyzed, and the correlation between the heavy metal content in root soil and different parts of A. argyi was analyzed, the pollution status of A. argyi root soil was evaluated by single factor pollution index, Nemerow comprehensive pollution index and geo-accumulation index, respectively. The results showed that: (1) the heavy metal pollution in the soil of the sampling sites was extremely serious. Compared with the background value of the soil in the county, the maximum exceeding multiples of heavy metal elements measured in the root soil of A. argyi were As 1582.6, Mn 11.4, Zn 44.3, Cu 32.6, Pb 12.2 and Cd 285.7, and the average exceeding multiples were As 545.37, Mn 2.60, Zn 7.56, Cu 4.77, Pb 5.50 and Cd 80.83, respectively. Among them, arsenic and cadmium pollution was the most severe, zinc pollution was more severe, lead pollution was the third, copper pollution was relatively light, and manganese pollution was the least. (2) The single pollution index and geo-accumulation index calculation results of the root soil of A. argyi were basically consistent. The Nemero comprehensive pollution index of the root soil of A. argyi at each sampling point was above severe, and the order of pollution degree of different heavy metal elements was: As>Cd>Zn>Pb>Cu. (3) A. argyi could tolerate the combined stress of multiple heavy metals in the soil, but it was not a hyperaccumulator for the measured heavy metal elements. (4) A. argyi had a relatively strong ability to enrich and transfer Mn, Zn, and Cu, and could transport them to the aboveground parts. However, the enrichment and transport ability of Pb, As, and Cd were weak, and they could be mainly accumulated in the roots. Due to its large biomass and low habitat requirements, A. argyi could be used for both stabilization and plant extraction of some heavy metals in the soil. Therefore, it could be used for phytoremediation of heavy metal contaminated soil.

Key words: Artemisia argyi, arsenic, heavy metal, combined pollution, soil remediation
