In the Region of Po-yang Lake,the range of mercury contents of environmental media were that in the sediments 0.038-0.055mg/kg,the fishes 0.017-0.029mg/kg(wet),and the water body of thelake≤0.00003mg/1 etc.
The time response for the concentration variation of 134'137Cs in the environmental media and dose evaluation in Suzhou city after Chernobyl nuclear accident is presented.
The time response for the concentration variation of 134,137Cs in the environmental media and dose evaluation in Suzhou city after Chernobyl nuclear accident is presented.
Since traditional environmental laws that center on the protection of environmental media fail to solve complicated environmental problems,a change must inaugurated in the research methodology and regimes of environmental law.
This text innovates and clicks lying in : Is it put in media studying in the ecology with media ecological environment relation to contain news by oneself, regard environmental media as a subsystem of the social information system, study its operation law and people and its interreaction.
The generation of OH radicals on UV-illuminated TiO2 surface is mainly responsible for the photocatalytic oxidation of pollutants in various contaminated environmental media.
Lead levels in different environmental media (soil, grass leaves, water, ceramics, pencil, paint, crayons and cosmetics) were determined to assess the major sources of lead exposure in Thohoyandou, South Africa.
Some differences were observed in the response of CF and normal cells to environmental (media) changes.
Speciation analyses in different environmental media suggested that Zn is a metal of future potential concern.
Quantitative assessments of potential human-health consequences from contaminants in environmental media routinely involve conservative deterministic, screening-level calculations of exposure and risk.
In the Region of Po-yang Lake,the range of mercury contents of environmental media were that in the sediments 0.038-0.055mg/kg,the fishes 0.017-0.029mg/kg(wet),and the water body of thelake≤0.00003mg/1 etc.The enrichment factors of fishes and shellfisheswere 10~3 and 10~5,respectively. The sources,accumulations and migrations of mercury of environ-mental media are discussed.
Environmental effects from the radioactive substancereleased from the Chernobyl accident in April 1986 are reviewed. Someaspects of these effects are introduced,including radiological monitoringcarried in the surrounding and distant area,the transfer of the plumesubstance in the environment,radioactivity level of radionuclides inthe environmental media,the burdens in human body and the pathwaycontributions to the dose equivalents,the dose estimation and projection,the applications of the emergency intervention...
