摘要
分析了厦门西港潮间带表层沉积物中10种重金属元素的空间分布特征及其赋存形态。各元素平均含量(mg/kg)顺序为:Fe(32420)>Mn(688)>Zn(263)>Cr(76.7)>V(54.1)>Cu(53.9)>Ni(42.4)>Pb(37.9)>Sr(37.5)>Co(21.1),其中Cu、Ni、Zn、Co和Cr含量分别是厦门土壤元素背景值的6.6、6.4、5.4、4.6和3.3倍。形态分析结果表明,Fe、V、Co、Ni、Cr、Pb主要以残渣态形式存在,而Sr、Mn、Cu、Zn以非残渣态占优势;从湾内向海湾两端,Cu、Zn、Co、Ni、Cr、Pb的非残渣态所占比例呈下降趋势,沿岸排入的各种污水是厦门西港重金属污染的主要来源。地质累积指数结果表明,Cu、Zn、Co、Ni总体表现为偏中度污染,Cr为轻度污染,Mn、V、Fe、Sr、Pb为无污染。次生相与原生相分布比值结果表明,Fe、Co、V、Ni、Pb为无污染,Zn、Cr、Cu为轻度污染。
Distribution and speciation of 10 heavy metals in the intertidal surface sediments collected from Xiamen Western Bay were analyzed. The average concentrations(mg/kg) of the studied heavy metals showed the order of Fe(32420)>Mn(688)>Zn(263)>Cr(76.7)>V(54.1)>Cu(53.9)>Ni(42.4)>Pb(37.9)>Sr(37.5)>Co(21.1), wherein the concentrations of Cu, Ni, Zn, Co and Cr were 6.6, 6.4, 5.4, 4.6 and 3.3 times of Xiamen soil background values. The results of speciation analysis showed that Fe, V, Co, Ni, Cr and Pb mainly existed in residual fractions while Sr, Mn, Cu and Zn mainly existed in non-residual fractions. The proportion of non-residual Cu, Zn, Co, Ni, Cr and Pb showed decreasing trends from inner bay to both ends. The discharge of various wastewater along the coast was the main pollution source of heavy metals. Results of geo-accumulation index showed that Cu, Zn, Co and Ni presented moderate pollution, Cr presented slight pollution, while Mn, V, Fe, Sr and Pb presented non-pollution on the whole. According to the ratios of secondary phase to primary phase, Fe, Co, V, Ni and Pb showed non-pollution, while Zn, Cr and Cu showed slight pollution.
