Worldwide, 2012 was among the 10 warmest years on record according to the 2012 State of the Climate report released by the American Meteorological Society (AMS). The peer-reviewed report, with scientists from NOAA’s National Climatic Data Center in Asheville, NC serving as lead editors, was compiled by 384 scientists from …
The Department of Motor Traffic (DMT) will soon obtain the much-needed permanent Ambient Air Quality Monitoring Units which they plan to set up in Colombo and Kandy to monitor poisonous gases like Sulphur dioxide, Nitrogen oxide, Carbon monoxide, Ozone, Hydro carbon and other particulate matter in the air. Vehicle Emission …
The Motor Traffic Department granted a Mobile Ambient Air Quality Monitoring Unit to the Central Environmental Authority (CEA) last Thursday to keep a tab on atmospheric pollution. The financial provisions for the mobile unit was provided under the Vehicular Emission Test Trust Fund, and it was received by CEA Chairman …
The U.S. Environmental Protection Agency’s 2008 standards for ozone pollution, challenged by both industry and environmentalists, were upheld by a federal appeals court that ruled the agency properly weighed science and policy. More than a dozen states sued the regulator in 2008 during the administration of President George W. Bush, …
Human-caused outdoor air pollution may be responsible for over two million deaths worldwide - a large number of them in South Asia and East Asia - each year, US researchers have said. A study, published in the journal Environmental Research Letters, has estimated that around 470,000 people die each year …
Increased concentrations of ozone and fine particulate matter (PM2.5) since preindustrial times reflect increased emissions, but also contributions of past climate change. Here we use modeled concentrations from an ensemble of chemistry–climate models to estimate the global burden of anthropogenic outdoor air pollution on present-day premature human mortality, and the …
Poor air quality linked to premature deaths, with London one of the worst cities in Europe for some pollutants The health effects of air pollution have been underestimated and Europe should review its laws to tackle the problem, UN scientists have concluded after a major review of new evidence. Sixty …

New Delhi: The prolonged heatwave in Delhi since May 18 not only saw extremely high temperatures ranging between 44 and 46 degrees but also led to the development of a dangerous pollutant that has become an annual feature in the capital lately. In the last week of May, levels of …
Coal is the primary fuel for electricity generation in India and its usage is continuously increasing to meet the energy demands of the country. This paper presents emissions from thermal power plants in India and contribution of power plant emissions in the formation of ground level ozone which shows considerable …
The WMO’s Statement on the Status of the Global Climate says that 2012 joined the ten previous years as one of the warmest — at ninth place — on record despite the cooling influence of a La Niña episode early in the year. The 2012 global land and ocean surface …
Los Angeles may boast some of the best weather among U.S. cities while scoring high in celebrity sightings, but the Southern California metropolis remains unable to shake off its more notorious No. 1 rankings for worst smog and heaviest traffic. Los Angeles, the nation's second-largest city, again topped the charts …
Fraction of exhaled nitric oxide (FENO) is a promising non-invasive index of airway inflammation that may be used to assess respiratory effects of air pollution. We evaluated FENO as a measure of airway inflammation after controlled exposure to diesel exhaust or ozone. Healthy volunteers were exposed to either diesel exhaust …
Air pollution exposure is associated with hospital admissions and emergency room visits for cardiopulmonary disease and stroke. Iceland's capital area, Reykjavik, has generally low air pollution levels, but traffic and natural sources contribute to pollution levels. The objective of this study was to investigate temporal associations between emergency hospital visits …
Recent crop harvesting practices use mechanical harvesters in the rice and wheat farm system in India. These practices leave behind large quantities of crop residue in the field. However, there is no suitable method available for managing the crop residues. Crop residues / biomass burning are cheap and easiest method …
The State of the Air 2013 report looks at levels of ozone and particle pollution found in official monitoring sites across the United States in 2009, 2010, and 2011. The report uses the most current quality-assured nationwide data available for these analyses. The report examines particle pollution (PM2.5) in two …
A daily health advisory in Delhi to warn people about the noxious air quality may be on its way. The advisory intends to inform the public about the levels of carbon monoxide, ozone and other hazardous particles in the air, helping warn those with vulnerable lungs and also encouraging the …
Fewer European countries could face fines for breaching air pollution limits after recession slowed industrial activity and limits on sulfur emissions kicked in. Eight EU states, including France and Germany, are likely to have failed to meet EU emission standards in 2011, down from 12 countries in 2010, according to …
The city has joined the list of the country's most polluted cities, with high level of particulate matter being detected in downtown Pune. A sure shot indication of how polluted its air is evident in the latest data of the System of Air Quality Forecasting and Research (SAFAR) that shows …
In an effort to prove that pollution affects the rich and the powerful as much as the common man and the homeless, a court-appointed body is working to put up an air monitoring device on Chief Minister Sheila Dikshit's house. The monitor would specifically detect levels of ground-level ozone, which …
