摘要:
采用电感耦合等离子体发射光谱(ICP-AES)法,分析泉州湾滩涂沉积物及互花米草成熟植株体内Cu,Zn,Ni,Mn,Co,Fe,V,Pb,Cr等金属的质量分数,研究互花米草的叶、茎、根对不同重金属的富集程度和富集能力,以及共存金属元素对金属富集的影响.研究表明,互花米草的叶、茎、根内含一定量的Cu,Zn,Ni,Mn,Co,Fe,V,Pb,Cr等金属元素,泉州湾滩涂沉积物存在Cu,Pb,Zn,Cr的污染,互花米草植株体内也有一定程度的重金属污染,不再具有原来的经济价值.互花米草植株的根对Mn,Cr,Cu,Fe,Ni的富集系数大于或接近1.重金属元素的共存能促进其他重金属的吸收,降低滩涂沉积物中重金属的质量分数.单株互花米草富集的重金属总量较大,互花米草的生物量大,通过收割富集重金属的互花米草地上部分,可以有效地降低互花米草生长环境中水体或沉积物的重金属质量分数.
Abstract:
The concentrations of heavy metals in the sediments and Spartina anglica developing in the Quanzhou Bay were analysed by using ICP-AES.The extent and ability to different heavy metals′ enrichment in the leaves,stems and roots were investigated.The effect of mutual metals on the enrichment of other metal was analyzed simultaneously. The result showed that metals such as Cu,Zn,Ni,Mn,Co,Fe,V,Pb,Cr were detected in the leaves,stems and roots.The beach of Quanzhou Bay was polluted by Cu,Pb,Zn,Cr to some extent,and the Spartina anglica plant was also contaminated by heavy metals,not worth of its original economic value. The enrichment coefficient were larger than or near to 1 for roots adsorbing metals such as Mn,Cr,Cu,Fe and Ni.The coexistence of some heavy metals could enhance the enrichment of other metals in the plant or sediments,and reduce the total quantity of metals in the environment.The quantity of heavy metal enrichment in an individual Spartina anglica was significant.Harvesting the over-ground part of Spartina anglica could decrease the total quantity of heavy metals in the Quanzhou Bay to a great extent.
