Assessing the overall environmental impacts of Vindhyachal super thermal power project at Singrauli

Environmental Impact Assessment (EIA) is concerned primarily with significant environmental impacts. Environmental Assessments (EA) describes the whole process by which information about the environmental effects of a project is collected and assessed by the development before deciding whether to grant planning permission. This study assesses the overal environmental impacts of …

Physico-chemical characteristics of flyash

It is well known that 50-60% of power generated in India is from thermal power stations. These thermal power plants use coal as a fuel. The high ash content of these coals pose a serious problem to the environment. The flyash production rate is about 25 million tonne for every …

High radioactive toxicity

Scientists have detected an overload of radioactive compounds in the flyash in villages surrounding the 1,260 megawatt Kolaghat Thermal Power Station in West Bengal's Midnapur district. In addition, the tube well water in these villages contain very high levels of toxic elements. While the flyash was found containing high levels …

Probabilistic modeling of sulfur and nitrogen pollution controls and their relations with income

The objective of this article is to evaluate (via modeling) the impact of different pollution control scenarios on the shape of the income-emissions relationship. The simulation of emissions and emission controls was conducted using the Climate Change Risk Assessment Framework, which projects SO2 and NOxemissions from energy consumption and conversion …
