In this paper, a probe into the stabilization effects of ferrous sulfate (FeSO4) came from two aspects-stabilization efficiency and leachate content. Fe/As molar ratio, arsenic pollution intensity, soil pH, reacted time interval, competitive ions, such as sulfate(SO42-), phosphate(PO43-) and zinc ion(Zn2+), were studied in order to discuss their effects on the stabilization of arsenic. Results show...
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...
It is important to evaluate and monitor the environmental impacts by the activity in our hand with appropriate methods, and the geophysical techniques have often been using in the subsurface environmental monitoring and remediation processes. In the study an Electromagnetic survey (EM) is performed to delineate deeply the extent of contamination at an industrial abandoned site, to detect the spread...
Contamination of the shallow aquifer by elevated nitrate concentrations is a common problem in many rural regions of the world. An aquifer that has both aquifer intrinsic vulnerability and irrigated land uses is especially susceptible to this type of contamination. A study was carried out to evaluate an aquifer's intrinsic vulnerability and agricultural activity's impact on groundwater quality in...
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...
