Ecological protection

We will discuss the main features of the offered system. At the lower level the state of all potentially dangerous sites - both natural and technogenic will be controlled. The periodicity and the facilities for carrying out the control over these sites is the concern of special expert subsystems, established on the basis of technical documents (for technical sites) or of data from the Ministry for ecological protection (for natural objects). For example, the sites of the first category should be equipped with special checking for the reliability of the security systems located directly on the site and continuous supervision of the status.

The results of the pathway screening analysis are used to develop a conceptual model of the site identifying applicable source media, transport mechanisms, and receptors. The Conceptual Exposure Flowchart, shown on Figure 2, can be used to document site-specific exposure conditions in this manner. Upon completion of the pathway screening analysis, pathways determined to be potentially complete based on the various screening criteria, should be retained for site-specific evaluation. However, if the preliminary screening analysis shows no complete exposure pathways, no further action is required to achieve health/ecological protection. 

Because of different coastal conditions, needs of lands, requirements for economic development, and the viewpoints toward ecologic protection, the utilization of coastal area, the land, and the sea, are different from country to country. Combining the articles published in international jornnals in related fields, utilization of coastal area could be sorted into the following categories ... 

In a word, this power generation leaching not only can generate electricity, but also reduce the purified steps of the leaching solution and the reagents consumption as well as is able to adjust the reaction evolution by control of the power output. From the point of view of the economy and ecological protection, this is a worthy advocating method. 

A chemical substance that is above its critical temperature and critical pressure, resulting in properties between those of a liquid and a gas. Development that meets the needs of the present without compromising the ability of future generations to meet their own needs. The concept considers the impact of a process on ecological protection, society, and economic viability. 

Scholler s booklet on Flechten 640) deals with the history, biology, systematics, ecology, protection and cultural significance of hchens and contains numerous colourful photos. Two other popular articles on lichens have been pubhshed by Shamoff and Sharnoff 645) and by Ahmadjian (5) who also discussed the problems of lichen symbiosis ((5). Huneck 388) gave a review on the significance of hchens and their metabolites. 

The main technical requirement during realization of the second factor for ecological protection, namely, development of chemical analysis methods and equipment, is high sensitivity. The necessary level of sensitivity is determined by the maximum permissible concentrations of toxic chemicals.
