Pollution environment has important influence to soil physical property, however, the method and theory of pollution soil research are not mature. The paper states chemical reaction with pollution solution, inducing dissolve and deposit effect, which is the immanent cause of physical mechanic property of soil. The soil samples of Dalian region have been soaked in sulphuric acid solution and sodium...
The watershed Landscape characteristics are important variables that influence surface water quality. Freshwater research and management efforts could be greatly enhanced by a better understanding the relationship between these variables and surface water quality. The major focus of this paper involved modeling relationships between watershed characteristics variables and water quality indicators...
In order to study the geochemical characteristics and medical values of geothermal water in Xi'an, 78 water samples were collected and analyzed. Results show the main factor affecting the chemical composition of geothermal water in Xi'an is the depth of the geothermal reservoir. The temperature, TDS and the concentration of SiO2 of geothermal water generally increase with the depth of geothermal reservoir...
Asbestos minerals (Amosite, Crocidolite, Chrysotile, Tremolite, Anthophylite) were mined extensively in South Africa for more than ninety years. The mines were later closed because of the negative health and environmental impacts, thereafter commissioning the mine rehabilitation process in 1986. Since then, there has not been an effectively coordinated monitoring procedure to assess the progress of...
