| 摘 要： | 用石墨炉原子吸收分光光度法测定了渤海潮间带沉积物中Zn,Cu,Pb,Cd,Cr和Ni。研究结果表明,渤海西南部潮间带沉积物中重金属含量基本正常,但Zn的污染较为明显,可能与油田排污有关。黄河口重金属含量从高潮带向低潮带逐渐降低。本区沉积物具有相似的地球化学特性。沉积物中重金属含量与有机质含量密切相关,它们易与有机质结合,而沉降至底质。

| Abstract: | Contens of Zn, Cu, Pb, Cd, Cr, Ni in sediments of high, middle, and low tidal zone was determined by graphite furnace atomic absorption spectrometry. It is indicated that contents of heavy metals are in normal values, but concentrction of Zn is much higher, which is probably due to oil field pollution. Heavy metal concentration in Huanghe River Estuary progressively decreases from high tidal zone to low tidal zone. Sediments of this area have similar geochemical characters. And heavy metal contents are closely related to organic matter contents. |
