This study is supported by the agriculture geochemical survey project in Dakang town, Jiangyou city. By analyzing the heavy metals and organic pollutants contained in the surface soil, a assessment of soil quality is made in the study area by introducing single-index and comprehensive-index evaluation analysis, as well as by using GIS .The evaluation shows that nearly 1/3 areas of the land in the...
Based on new portable instruments (mini-medium-volume sampler), intensive samplings on inhalable particulate matter (PM10) in Jiaozuo city have been conducted, the mass concentrations of PM10 was weighted, and the content of parts of heavy metals of PM10 was tested by ICP-MS in this paper. The relationship between the concentration of PM10 and the meteorological condition was discussed. The experiments...
Leachate from gangue is known as the main pollutants source to mining area soil and groundwater pollution. Long term leaching experiment are carried out to seek the long term effect on leachate chemistry of gangue under long term exposure to rainfall and atmosphere. Gangue from Xishan coal mine is used for long term dynamic leachate to analyze and compare the changes of the various metal ions in leachate...
Heavy metal accumulations in edible plants are commonly reported by scientist to alert the public on potential risks of toxicity effects. The study was conducted to determine the heavy metal accumulation in different part of the plant tissue namely Ipomoea reptans and Helianthus annuus. Spent batteries were utilized as the source of contamination with natural leaching process. Results indicated that...
This paper is a pilot study on the effect of grass- microorganism combined bioremediation of atrazine contaminated soil. Sorghum hybird sudangrass and ryegrass were selected as two repair grass, and immobilized degrading strain J2 was added into the soil under the indoor pot conditions. When the concentration of atrazine was 20 mg/kg in the soil, grass-microorganism combined bioremediation enjoyed...
