Targeting the Monetary Base: The Swiss Caseranking cities in economic development in southeastern China, Shanghai and Nanjing, based on exploration and a lot of laboratory work. In these cases, the studies are carried out mainly on urban water systems, urban rivers and urban lake. The cases on the pollution of trace metals from the urban wat

Transmuting Profits into Interestviors of the trace metals from soil, mineral, or rock are carried out in these experiments. The behaviors and factors of the trace metals to be adsorbed and desorbed in media are discussed based on experiments and the speciation concentration features of the trace metals. A mathematical model on tra

The “three-step procedure” for trace metal speciation analysis is raised, based on the ease and usefulness in environmental research and protection practices for trace metal speciation analysis with comparison within current main procedures of the

,The Metropolis Pollution of Trace Metals—Shanghai and Nanjing, China,em crises of Zn, Hg, and Cd with the feature of obvious higher levels of Zn, Hg, and Cd in the water system of the Suzhou Creek than that in similar systems in other nations are pointed. In addition, it is proved in this study that the trend of the level change in different depth of the sediment is

The Experimental Research on the Behaviors of Trace Metals,t the ratio of the concentration change of the trace metals released from the carriers is generally constant, which may be the property of the element releasing in solution under usual conditions. It reveals a positive correlation between the acid stage of the system, the degree of the temperature o
