| 摘 要： | 分别于1989年，1992年，1991年8月，1991年5月对大辽河口、鸭绿江口、滦河口、东村河口水体中总汞进行了取样和分析，其中又对大辽河口和东村河口进行了溶解态汞的分析。大辽河口和东村河口溶解态汞的含量分别为85～460ng/L和180～500ng/L，平均值分别为210和324ng/L；总汞含量分别为95～550和400～1000ng/L，平均值分别为310和640ng/L。大辽河河流段和河口段溶解态汞和颗粒态汞是主要存在形式。河口溶解态汞和颗粒态汞随氯度变化趋势相似。东村河口溶解态汞约占50%。鸭绿江口和滦河口总汞含量分别为30～2500和3700～6700ng/L，平均值分别为700和5700ng/L。鸭绿江口总汞随氯度变化趋势与随浊度变化趋势一致。而在滦河口总汞含量随两者变化趋势则不同。还讨论了滦河口、东村河口、鸭绿江口和大辽河口汞的污染程度。

| Abstract: | Dissolved(DM) and total (TM: dissolved and particulate)mercury were measured for surface water samples taken from the Daliaohe and Dongcunhe estuaries in 1989 and 1991 respectively. In the Yalujiang and Luanhe estuaries, only total mercury (TM) were measured in 1991 and 1992. DM was the main form in the river and PM was the main form in the Daliaohe estuary; 50% of TM was in DM in the Dongcunhe estuary. The DM and suspended particulate matter (SPM) had similar trends with the chlorinity in the Daliaohe estuary. In the Yalujiang, the total mercury varied with chlorinity, which coincided with the turbidity. But in the Luanhe, the relation of total mercury with the chlorinity was different from that for the SPM. Based on the data of this study, it can be concluded that the estuaries of Luanhe, Dongcunhe, Yalujiang and Daliaohe were all heavily polluted by mercury, especially the Luanhe estuary. |
