摘要:
2016年对浙江省长兴县仙山湖湿地11个树种的根茎叶及根际土壤进行采样,对样品中Cu,Cd,Zn,Pb,Hg含量及其在不同营养器官的积累特性进行测定并分析。结果表明,土壤总体上处于健康状态。不同树种及同一树种的不同器官中的重金属含量绝对值有很大差异,Cu含量在女贞Ligustrum lucidum根、旱柳Salix matsudana茎和乌桕Sapium sebiferum叶中最高(分别为49.267 mg?kg-1,25.302 mg?kg-1,26.308 mg?kg-1),Zn含量在乌桕根和旱柳茎、叶中最高(分别为212.105 mg?kg-1,262.030 mg?kg-1,89.804 mg?kg-1),Cd含量在日本三蕊柳Salix triandra var. nipponica(春)根和旱柳茎、叶中最高(分别为1.613 mg?kg-1,1.443 mg?kg-1,0.723 mg?kg-1),Hg含量在樟Cinnamomum camphora根、茎和水竹Phyllostachys heteroclada叶中最高(分别为0.070 mg?kg-1,0.045 mg?kg-1,0.025 mg?kg-1),Pb含量在日本三蕊柳(春)根、叶和小蜡Ligustrum sinense茎中最高(分别为12.113 mg?kg-1,11.050 mg?kg-1,5.930 mg?kg-1)。11种树种不同器官对重金属的富集系数(BCF)变化范围为0.06 ~ 22.50、转移系数(TF)变化范围为0.10 ~ 3.57。除樟、女贞和水竹根部的Cu含量略高于Zn外,其他树种不同营养器官中重金属含量基本表现出“N”字形变动趋势;重金属元素在不同植物不同器官中的含量一般呈现Zn>Cu>Pb>Cd>Hg的变化规律。
Abstract:
Field sampling of leaf, stem, root and rhizospheric soilwas implemented on 11 tree species in April, 2016 in Xianshan Lake wetlandin Changxing, Zhejiang province. Determination was carried out on content of Cu, Cd, Zn, Pb and Hg. The results showed that the soil was healthy, though the concentration of Zn, Cd, Pb and Hg wasslightly higher than the national standard for grade one. The content of Cu was the highest in root of Ligustrum lucidum, stem of Salix matsudanas and leaf ofSapium sebiferum, respectively 49.267, 25.302 and 26.308 mg?kg-1. The content of Zn was the highest in root of S. sebiferum, stem and leaf of S. matsudana, respectively 212.105, 262.030 and 89.804 mg?kg-1. The content of Cd was the highest in root of S. triandra var. nipponica roots, stem and leaf ofS. matsudana, respectively 1.613, 1.443 and 0.723 mg?kg-1. The content ofHg was the highest in both root and stem of Cinnamomum camphora and leafof Phyllostachys heteroclada, respectively 0.070, 0.045 and 0.025mg?kg-1. The content ofPb was the highest in both root and leafof S. triandra var. nipponica (in summer) and stem of L. sinense, respectively 12.113, 11.050 and 5.930 mg?kg-1. Bio-concentration factor of Cu, Cd, Zn, Pb and Hg in tested plans ranged from 0.06-22.50, and translocation factor from 0.10-3.57. The determination found that the content of heavy metals in different plant organs in different tree species was orderedby Zn>Cu>Pb>Cd >Hg, and that in rhizosphere soil showed similar curve.
