摘要
测定了波斯湾东北部Arvand河表层沉积物中重金属铜(Cu)、镍(Ni)、镉(Cd)、钴(Co)、铅(Pb)和汞(Hg)的分布和季节变化。重金属浓度随季节和采样地点的不同而变化。沉积物中重金属的浓度顺序为Ni > Cu > Co > Pb > Cd > Hg, p有机质>易交换性>酸还原性。Cu(4.5)和Ni(3.6)的Igeo值在河流上游7月高于其他季节。Ni的BAFs显著高于其他金属,其次是Cu、Co、Pb、Cd和Hg。这些结果表明,Ni和Cu比其他元素更容易获得。所分析的重金属在沉积物样品中的浓度均符合NOAA和ROPME提出的沉积物质量指南中的平均浓度,但在某些情况下镍的浓度除外。
Distribution and Seasonal Variation of Heavy Metal in Surface Sediments from Arvand River, Persian Gulf
Distribution and seasonal variation of heavy metals copper (Cu), nickel (Ni), cadmium (Cd), cobalt (Co), lead (Pb) and mercury (Hg) were measured in the surface sediments samples taken from Arvand river in the northeast Persian Gulf. Concentration of heavy metals varied depending on different season and sampling sites. The concentration order of heavy metals in sediment were Ni > Cu > Co > Pb > Cd > Hg. There was significant difference (p organic matter > easily and exchangeable > acid reduction. Igeo values calculated for Cu (4.5) and Ni (3.6) showed higher values in the July month in the upstream region of the river than in the other seasons. BAFs of Ni were extremely higher than other metals followed by Cu, Co, Pb, Cd and Hg, respectively. These results indicate that Ni and Cu are more easily available than other elements. The analysed heavy metals were found in sediment samples at mean concentration in the sediment quality guideline proposed by NOAA and ROPME, except for Ni concentration in some cases.
