Cutting down tailpipe emissions with e-vehicles

At nearly 55%, electricity generation in India is primarily through coal. So like in the case of the U.S and China, net reduction in carbon emission will not be much even when if there is large-scale adoption of electric vehicles in India. Still, cities and towns using electric vehicles in large numbers will see a reduction … Continue reading Cutting down tailpipe emissions with e-vehicles

IIT Bombay’s bacteria preferentially degrade aromatic compounds

IIT Bombay researchers have used a unique strain of bacterium isolated from soil contaminated with petroleum products to selectively remove toxic aromatic pollutants from the environment. The bacteria devour aromatic compounds and organic acid even when glucose is available. The peculiar order of food preference comes from the suppression of glucose utilisation at a molecular … Continue reading IIT Bombay’s bacteria preferentially degrade aromatic compounds

Emissions from ships can impact monsoon activity over Bay of Bengal

Using surface and satellite data, a team led by scientist M.V. Ramana of the Hyderabad-based National Remote Sensing Centre has found that aerosol plumes from ships produced severe pollution along the international shipping route in the Bay of Bengal. According to a paper published on August 2 in the journal Scientific Reports, emissions from ships … Continue reading Emissions from ships can impact monsoon activity over Bay of Bengal

Outdoor air pollution killed 0.65 million Indians in 2010: study

These deaths were in adults older than 30 years and in children younger than five years. India has the second highest premature deaths caused by outdoor air pollution. With 1.35 million deaths annually, … Continue reading Outdoor air pollution killed 0.65 million Indians in 2010: study

The pollutants causing discolouration of Taj Mahal identified

Finally, the specific pollutants in the air that are responsible for the discolouration of the white marble of Taj Mahal have been identified. Particulate carbon and fine dust particles that are deposited on the marble are responsible for its browning. Carbon is of two types — black carbon and light absorbing organic carbon or brown … Continue reading The pollutants causing discolouration of Taj Mahal identified
