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...
This paper investigated the spatial-temporal variations and pollution source of surface water quality by analyzing the data from 8 water quality monitoring stations along the middle and lower reaches of the Min River between 2003 and 2008. The results showed that surface water quality was worse in the middle reaches of the Min River than that in the lower reaches and its tributary. Seasonal and spatial...
The Distribution of shallow groundwater containing beryllium were summarized and the major factors influencing beryllium enrichment were discussed in this paper, based on chemical data of Be, aluminum and pH from more than 900 groundwater samples in the Pearl River Delta. The results show that Be concentration ranges from less than 0.02μg·L-1 to 40.3μg·L-1, with the majority less than 0.05μg·L-1 and...
Around 2300 tanneries in India produces 6000 tones of solid waste per annum, that includes 15000 tones of chromed leather shavings waste. This contain Chromium. Cr (VI) compounds used in leather processing which are highly water soluble, toxic, carcinogenic and a potential ground water contaminant. The MoEF have classified the chromium bearing solid wastes in the hazardous waste category that necessitates...
The efficiency of electrokinetic remediation of zinc contaminated soils and the influence of complex EDTA were researched by means of experiment for the complicated remediation of soil contaminated by typical heavy metal in this paper, and migration and variation characteristics of zinc were analyzed too. The experimental results indicated that the heavy metal pollutant could be enriched and removed...
This study aims to assess the groundwater pollution potential by Beheshte Zahra Cemetery, Tehran, Iran. Surly there is the penetration of decomposition products into seepage, during the fate of human corpses. This seepage contains bacteria, viruses and organic and inorganic chemical decomposition products. In this investigation, analyzing the data gathered about Beheshte Zahraha has been done; the...
Sewage irrigation is one of the methods to solve water shortage in north China Plain. The wastewater usually come from urban domestic and industrial sewage, inappropriate sewage irrigation can pollute soil and crops by heavy metal depositing. Thereby impact on health of humanbeing indirectly. This paper try to monitor the impact of heavy metal on wheat leaves by hyperspectral remote sensing. Results...
Heavy metals, such as cadmium, mercury etc, if not being properly disposed, may beget serious pollution to the environment, enter ecosystem sooner or later, and get into life chain and food chain, ultimately incur heavy threaten to humanpsilas health. Heavy metals enter the food chain via many ways, the first step pollutes the soil, after that pollutes plants which grow in the polluted soil; or directly...
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...
