| 摘 要： | 东湖底泥中金属Pb、Cd、Cu、Fe平均含量分别为44mg/kg、2.63mg/kg、62mg/kg、5.9×104mg/kg.铅近年来有所下降,镉比土壤背景值高出近10倍.铁的垂直分布与沉积物间隙水的pH、Eh在0～28cm范围内有很好的相关性:当Eh升高时,pH下降,Fe含量增加;当Eh下降时,pH升高,Fe含量下降.

| Abstract: | Average contents of lead,cadmium,copper and iron in sediment are 44 mg/kg,2.63 mg/kg,62 mg/kg and 5.9×104mg/kg respectively.Vertical distribution of lead shows that its content has decreased in recent years.Cadmium is 10 times higher than soil background value.The vertical distribution of iron is related to pH and Eh of interstitial water in 0~28 cm range: iron in-creases with high Eh and low pH and decreases conversely. |
