The results of counts (MPN) show that dinitrifiers arc found to vary between several hundred and several million bacteria ml-1 in the waters of Jiulong River Estuary and along Xiamen coast.Denitrifying bacteria usually occur more in the coastal areas near city or town,side of the bank and also near the ezit of domestic sewage than other places.The quantity of bacteria occuring in the surface water and in the ground floor water shows two different phenomenon: One is that bacteria occur more in the ground floor...

The results of counts (MPN) show that dinitrifiers arc found to vary between several hundred and several million bacteria ml-1 in the waters of Jiulong River Estuary and along Xiamen coast.Denitrifying bacteria usually occur more in the coastal areas near city or town,side of the bank and also near the ezit of domestic sewage than other places.The quantity of bacteria occuring in the surface water and in the ground floor water shows two different phenomenon: One is that bacteria occur more in the ground floor water than in the surface water and another is just the opposite.The density of denitrifying bacteria is close relationship with the content of the domestic sewage drained into estuary and ressidual currents in the estuary.Through tests from generation to generation and tests by contrast,it is proved that most of the denitrifying bacteria under the examination of the present reserch belong to the freshwater population derived from domestic sewage.

应用MPN法检测了九龙江口和厦门市区沿岸水域中的反硝化细菌的数量为几百至几百万个/毫升;表层水的菌数,近市镇水区比远市镇水区多,“远岸”比岸边少,越往外海越少;表层水和底层水的菌数关系存在着两种相反的现象:一种是底层比表层高,另一种恰好相反;反硝化细菌的密度与生活污水在河口和港湾中的排出量及余流密度相关;通过传代和对比试验,验证了本工作所检测的反硝化细菌大部分是来自生活污沟水中的淡水种群。

The average concentrations in Bast China Sea water are Zn2+ 7.3 (5.5 in 1976), Cd2+ 0.12, Pb2+ 0.036, and...

The concentrations of Zn, Cd, Pb, Cu ions are shown to foe similar in natural waters of Tianshan and Qinghai-Xizang (Tibet) plateau as well as in the sea. The metal speciation showed no significant changes throughout the natural water cycle.The average and variability of concentrations of trace metal ions in fresh water are respectively Zn2+ 5.7 ±26%, .Cd2+ 0.092±41%, Pb2+ 0.048±23%, and Cu2+ 1.1±18% ppb. The average concentrations in Bast China Sea water are Zn2+ 7.3 (5.5 in 1976), Cd2+ 0.12, Pb2+ 0.036, and Cu2+ 0.94 ppb.The phenomenon of a homogeneous distribution of trace metal ions in natural waters shows that the metal ions are carried in the water cycle. The rain water derives mainly from the evaporation of sea water; thus, the evaporation must carry trace metal ions from the sea into the air. The river water derives mainly from ram. water and runs into the sea. No significant equilibration transfer takes place between trace metal ions and particulate phases at the pH of natural waters.In the natural water cycle the trace metal ions are carried with the water. The transfer is not determined by the energy of the metal ions and, consequently, the thermodynamics do not present a problem. "When an ion occurs at trace concentrations the influence of the environment (the medium) will be of great importance, and the ion will not observe the rates of thermodynamic equilibrium theory. It may be concluded that the thermodynamic theory does not apply directly to physico-chemical processes at trace levels. In this case the free energy, G, can not be used directly to predict the feasibility of physico-chemical processes.

痕量Zn,Cd,Pb,Cu离子的浓度在天山和青藏高原天然水中以及在东海海水中都是相似的。在淡水中的平均浓度分别为Zn 5.7,Cd 0.092,Pb 0.048,Cu 1.1 ppb。这证明天然水中痕量金属离子均匀分布规律是客观存在的。
