Surface sediments along the south of Caspian Sea were collected to evaluate the contamination of heavy metals. The result ranged (μg/g, Fe% dw): Pb(13.06-33.48); Ni(18.01-69.63); Cd(0.62-1.5); Zn(30.11-87.88); Cu(5.86-26.37) and Fe(1.8-4%) respectively. Cadmium showed higher EF when compared to other sites. Geoaccumulation Index value for Cd in most stations was classified as moderately contaminated and moderately to strongly contaminated, as well as the average of I(geo) of Cd (1.77 ± 0.35) suggested that surface sediments of Caspian coast were moderately polluted by this metal. The result of the Pearson correlation showed that there were significant positive associations between Ni, Cd and Zn (r = 0.44-0.76; p < 0.01).
沿里海南部的表层沉积物被采集来评估重金属的污染情况。结果显示(μg/g,Fe% dw):Pb(13.06-33.48);Ni(18.01-69.63);Cd(0.62-1.5);Zn(30.11-87.88);Cu(5.86-26.37)和 Fe(1.8-4%)。与其他地点相比,Cd 表现出更高的 EF。大多数站点的 Cd 地积累指数值被归类为中度污染和中度到强污染,以及 Cd 的平均 I(geo)(1.77 ± 0.35)表明里海海岸的表层沉积物受到该金属的中度污染。Pearson 相关性的结果表明 Ni、Cd 和 Zn 之间存在显著的正相关关系(r = 0.44-0.76;p < 0.01)。
