重金属

The results showed that PSAC had many excellent properties such as high hardness , large adsorption range , good adsorbing ability to typical toxic molecules in blood ,low content of heavy metalions , low hemolysis ratio , few released particles and no pyrexic source and germs . Satisfactory results have been obtained in clinical experiments for blood purification , which show that PSAC can be used as an adsorbent for a man-made kidney.

结果表明：沥青基球状活性炭球形度好，强度高，具有良好的广谱吸附性能，对血液中典型的中、小毒性分子吸附能力强，重金属含量低，溶血率低，微粒释放量少，无热源、无菌，血液灌流临床试验效果满意，可以作为人工炭肾的吸附剂。

The lower the partition coefficient existed, the more easily the remobilization of heavy metals from sediment particles occurred.

分布平衡系数kD愈小，代表重金属愈易释出，锌及镍比铅及铬更易於释出到孔隙水中，而铜最不易释出到孔隙水中。

This may indicate that a reprecipitation with phosphate happened during prolonging the extraction period.

The factor analysis showed that the resuspension of mud and sand and salinity caused by river runoff and the mixture of fresh and salt water was the main reason of the variation of heavy metal content in the Huanghe estuary water.

主成分分析表明，河水流量的大小和咸淡水的混合导致的泥沙的再悬浮和盐度影响到河海混合过程及河口重金属的浓度变化趋势。

The main reason for this was resuspension.

随后又有升高，主要原因为沉积物的再悬浮；在丰水期距离A03站点11.5～15km，重金属浓度有低谷河段，随后又有一峰值，该位置比枯水期推后了约1.3km。

As one of common pioneer plants growing on mine tailings in Yunnan Province, Rumex dentatus has generated metal tolerant ecotype and could therefore be treated as an ideal experimental material for stress ecology study.
