Air pollution has reportedly been linked to irregular heart beat and blood clots, and now new research suggests that it may lead to an increased risk of stroke and anxiety as well, especially in developing countries. Usually factors like obesity, smoking and high blood pressure put people at a great …
Outdoor air pollution is an important risk factor for cardiovascular disease throughout the world, with particulate air pollution alone responsible for over three million deaths each year. Increases in concentrations of daily air pollution are associated with acute myocardial infarction and admission to hospital or death from heart failure. These …
New findings presented at the 249th National Meeting & Exposition of the American Chemical Society (ACS) show that air pollutants may have something to do with the severity of our allergies during the transition from spring to winter. "Scientists have long suspected that air pollution and climate change are involved …
WMO has confirmed continuation of warming trend over the past few decades, with 14 of the 15 hottest years on record occurring this century. Record ocean heat, high land-surface temperatures and devastating flooding were some of the defining characteristics of the global climate in 2014, which was nominally the warmest …

The HadGEM2 earth system climate model was used to assess the impact of biomass burning on surface ozone concentrations over the Amazon forest and its impact on vegetation, under present-day climate conditions. Here the researchers consider biomass burning emissions from wildfires, deforestation fires, agricultural forest burning, and residential and commercial …
Some key pollutants fell, but government and environmentalists at odds over why The concentration of ozone in the city's air has increased by a third in the last 15 years, highlighting yet again the severity in regional air pollution, preliminary government data has shown. But despite the uptick, the Environmental …
Final report on air quality status in the National Capital Region as per Hon’ble National Green Tribunal order in the application No. 21 of 2014 (In the matter of Vardhman Kaushik Vs. Union of India). As per Order of Hon'ble National Green Tribunal (NGT) in its order on 04.12.2014 as …
While previous research helped to identify and prioritize the sources of error in air quality modeling due to anthropogenic emissions and spatial scale effects our knowledge is limited on how these uncertainties affect climate forced air-quality assessments. Using as reference a 10 yr model simulation over the greater Paris (France) …
At an EPA hearing, witnesses say the ozone standard needs to be tightened, despite businesses' opposition It is time to strengthen the nation's smog limits to improve the health of millions of people who suffer the ill effects of air pollution, dozens of environmentalists, doctors, asthmatic children and religious leaders …
Climate change and high rates of extinctions of animals and plants are pushing the Earth into a danger zone for humanity, said a scientific report card about mankind's impact on nature. An international team of 18 experts, expanding on a 2009 report about "planetary boundaries" for safe human use, also …
The variability of the levels of atmospheric particulate matter PM10 and its composition is assessed in the rural and urban zones of Mexicali during fall and winter 2008-2009, using a low level volume Minivol sampler, with quartz and Teflon filters. During fall the Mexican norm was exceeded (120 μg/m3 in …
Scientific Assessment of Ozone Depletion: 2014 is the quadrennial report of the Scientific Assessment Panel (SAP) of the Montreal Protocol on Substances that Deplete the Ozone Layer. The SAP assesses the state of the depletion of the ozone layer and relevant atmospheric science issues every four years and provides Parties …
The U.S. Environmental Protection Agency proposed tighter limits on emissions of smog-producing ozone, rules designed to reduce asthma and heart disease that critics said they may be among the costliest ever issued by the agency. The EPA published a proposal today for ground-level ozone, offering to tighten the levels to …
(Reuters) - The Environmental Protection Agency is expected to propose on Wednesday more stringent air quality standards for ground-level ozone, the main culprit in smog, sources said. Under a court-ordered deadline of next Monday to release its proposal, the agency could propose a National Ambient Air Quality Standard between 65 …
India, China, the Gulf and other large developing economies form the fastest-growing market for the refrigeration industry Despite India changing its stance and keeping quiet, select developing countries were able to delay the launch of formal talks on the phasing out of climate change-causing refrigerant gases under the Montreal Protocol, …
The effects of urbanization on ozone levels have been widely investigated over cities primarily located in temperate and/or humid regions. In this study, nested WRF-Chem simulations with a finest grid resolution of 1 km are conducted to investigate ozone concentrations [O3] due to urbanization within cities in arid/semi-arid environments. First, …
