Agriculture is multi-functional, producing economic goods including food, feed, fibre, and fuel, as well as providing several intangible or non-tradable services to society free of cost. Non-tradable services, unlike economic goods, remain unpriced; as a result, farmers are not compensated monetarily for the benefits of the several non-tradable services they …
Athletes and officials staying at the 2010 Commonwealth Games Village may get to travel on vehicles that will run on a newage green fuel. Indian Oil Corporation (IOC) has asked the government for land at the Village site to set up a hydrogen-CNG (HCNG) filling station. The green fuel is …
Globally, commercial ships emit almost half as much particulate pollution into the air as the total amount released by cars, according to a new study. Ship pollutants affect the Earth
New Delhi: If you feel dizzier in summer, there is a good reason for it. As the mercury mounts, a little-known summer pollutant comes to play, jeopardising public health. Ozone
health sciences Mussels in surgery Natural adhesive proteins secreted by marine mussels may replace sutures in surgery. Sutures, made from sheep intestines, are used to repair tissues in a surgery. Sutures can cause infection and inflammation. Synthetic adhesives are also used to repair tissues but they are not biodegradable and …
As the action is still awaited even after one month of the delivery of Environmental Protection Orders (EPOs) to owners, the brick kilns in Islamabad's vicinity continue polluting the capital. According to officials at the Environment Ministry, the EPOs were served to owners on March 18, though the Brick Kiln …
The government has decided to do something important about vehicular emissions that have reached highly dangerous levels. Federal Ministry of Environment told the National Assembly on Monday that all petrol-run vehicles would be required to comply with Euro-II emission standards with effect from July. The deadline for diesel vehicles' compliance …
The US Environmental Protection Agency said Thursday it is seeking public comment on whether to allow a higher level of ethanol to be blended into gasoline. Growth Energy and more than 50 ethanol manufacturers petitioned the EPA last month to raise the maximum blend level for ethanol in gasoline from …
Many people consider the wider use of biofuels a promising way of reducing the amount of surplus carbon dioxide (CO2) being pumped into the air by the world
Nitrogen-based fertilisers have helped all but eradicate famine in large parts of the world. But reactive nitrogen in circulation has now doubled. Owen Gaffney asks, what effect is this having on the carbon cycle?
Diesel exhaust particulate (DEP) is a key arbiter of the adverse cardiovascular effects of air pollution. This study assessed the in vitro effects of DEP on vascular function, nitric oxide (NO) availability, and the generation of oxygen-centered free radicals.
The European Parliament agreed in December to a proposal that emissions of nitrogen oxides from new heavy duty vehicles shall be cut by 80 per cent and those of particulate matter by 66 per cent, as compared to existing standards.
Sixteen EU countries are likely to exceed national limits on emissions of at least one of four key air pollutants set for 2010, according to an analysis carried out by the European Environment Agency (EEA).
Tropical forests can capture carbon FORESTS hold the centrestage in climate change. They can reduce carbon emissions up to 10-20 per cent of what has been projected by 2050.
