Natural radioactivity due to the presence of 40K, 238U and 232Th was measured in fly ash samples collected from economizer, aerator and electrostatic precipitator (EP) of the Chandrapur Super Thermal Power Station (CSTPS) using a NaI (Tl)-based gamma ray spectrometer. The study indicates an elevated concentration of these radionuclides, especially in the finer ash samples from EP, which may provide an exposure pathway through inhalation of airborne ashes and could probably cause severe environmental and human health problems.
The Odisha government on Saturday decided to close down the sponge iron plants failing to install electro-static precipitators (ESP) to stop pollution by end of June, said forest and environment minister Debi Prasad Mishra.
He said of the 107 sponge iron plants in the state, so far thirty percent of the units are creating pollution and have failed to replace their existing gas cleaning plants to
Ash from an erupting Icelandic volcano could reach northern Scotland by Tuesday and parts of Britain, France and Spain by Thursday or Friday if the eruption continues at the same intensity, airlines were warned Sunday.
The warning is based on the latest 5-day weather forecasts, but is being treated cautiously because of uncertainties over the way the volcano will behave and interact with the we
Bioremediation is an invaluable tool box for wider application in the realm of environmental protection. Bioremediation approach is currently applied
to contain contaminants in soil, groundwater, surface water, and sediments including air. These technologies have become attractive alternatives to
BHUBANESWAR: If all the power plants proposed in Orissa materialise, the huge capacity addition in energy generation would have brought about a bigger problem of ash.
With the State leaving no power generation option unexplored, it could well find itself in a tricky situation.
LUCKNOW: The two units of Parichha thermal power project, which are under the scanner of the Central Pollution Control Board (CPCB) for snuffing out fly-ash, thereby causing health hazard to thousands of villagers living around, have been waiting for almost five years for a mandatory renovation exercise, top sources in UP Rajya Vidyut Utpadan Nigam have revealed.
BHAWANIPATNA: Fly ash, red mud and lime grit are some of the wastes generated by alumina refineries and if not properly disposed of, these may cause health hazards. But the enterprising have the Midas touch. Many ancillary units have come up in the district which are thriving on these wastes. They use the wastes as material.
In India huge amount of flyash is generated from coal-fired thermal power plants, causing several disposal-related problems. The disposal of coal ash is a matter of great concern nowadays as it requires huge area of land at the disposal site but also adversely affects surface, sub surface environment. The present paper discusses the several environmental aspects of coal ash disposal.

Jorhat: A project sponsored by the central department of science and technology at Assam Agricultural University (AAU) to explore the use of flyash in the agricultural sector has shown
The present laboratory study reports the results of various engineering properties, such as compressive strength, tensile strength, flexural strength and impact strength of fibre reinforced concrete produced from waste plastic fibres and flyash which are the two environmental pollutants.
