CHINA saw a modest improvement in the levels of two common air pollutants in the first half of the year, environmental group Greenpeace East Asia said yesterday. Average levels of PM2.5 — the tiny particles that can penetrate deep into the lungs and are particularly hazardous to human health — …
In a report titled 'State of the Climate in 2014,' the American Meteorological Society has described 2014 as the warmest year on record. The World Meteorological Organization (WMO) has also reported that the January-June 2015 period was the hottest on record, citing figures provided by the National Atmospheric and Oceanic …
When Hamish Stewart bikes the streets of London, he clips a tiny digital device to his shirt collar or pants pocket. The wearable technology isn’t tracking the distance he travels or the calories he burns: Instead, it measures how many toxic pollutants from cars, buses and factories are sullying Stewart’s …
Cutting levels of soot and other short-lived pollutants delivers tangible benefits and helps governments to build confidence that collective action on climate change is feasible. After the Paris climate meeting this December, actually reducing these pollutants will be essential to the credibility of the diplomatic process. (Opinion)
Air pollution is a major concern of now days. It is caused by many gaseous as well as particulate pollutants. The ground level O3 and SPM (PM2.5) are the two essential sources which can fluctuates the quality of ambient air in the atmosphere. The diurnal average of O3 and PM2.5 …
This study aims to determine the variability and trends of tropical biomass burning, tropospheric ozone levels from 2005–2012 in Thailand and the ozone transport from the surrounding regions. Intense biomass burning and tropospheric ozone in this area have a seasonal variability with the maximum generally occurring during the dry season. …
This paper presents a summary of the work done within the European Union’s Seventh Framework Programme project ECLIPSE (Evaluating the Climate and Air Quality Impacts of Short-Lived Pollutants). ECLIPSE had a unique systematic concept for 5 designing a realistic and effective mitigation scenario for short-lived climate pollutants (SLCPs: methane, aerosols …
Gagandeep Singh Sapra and his wife Harpreet, both avid cyclists, used to cover 40km every day till about a year ago. Now they barely cycle 40km in a week—both have developed allergic asthma that makes it difficult to do any activity involving exposure to polluted air. When their passion takes …
During the months of June and July 2013, over the Euro–Mediterranean area, the ADRIMED (Aerosol Direct Radiative Impact on the regional climate in the Mediterranean region) project was dedicated to characterize the ozone and aerosol concentrations in the troposphere. It is first shown that this period was not highly polluted …
Lutyens’ Delhi and hospitals are high risk zones, says latest CSE analysis This is bad news for those suffering from asthma and respiratory problems. It is dangerous if ozone increases even for short duration Rising NOx levels and volatile gases in the air, primarily from vehicles, form the recipe for …
A federal appeals court on Tuesday upheld the Environmental Protection Agency’s process for determining whether states are complying with air-quality ozone limits, ruling against states, industry groups and environmental organizations that challenged the rules. Reports the Associated Press: The U.S. Court of Appeals for the District of Columbia Circuit rejected …
The sudden boom in diesel cars and trucks in Delhi and the National Capital Region (NCR) has escalated the level of ozone gas in the air. Ozone, which forms an ultraviolet (UV) protection layer in the upper reaches of the atmosphere, is extremely harmful when produced at surface level. The …
Since 2005, Istanbul has been pedestrianizing select areas on the city’s Historic Peninsula. According to Assessment of the Air Quality Effects of Pedestrianization on Istanbul’s Historic Peninsula by EMBARQ team in Turkey, these measures have significantly improved air quality in the region. Furthermore, the report notes how pedestrianization is producing …
While pollutant counts fall in Pearl River Delta, concentration of harmful gas increases: report Air quality over the Pearl River Delta region improved last year as levels of three major pollutants dipped - but one worrying pattern was a worsening of the harmful ozone pollutant, an official report showed. The …
Researchers at the University of Houston have determined that climate change -- in the form of a stronger sea breeze, the result of warmer soil temperatures -- contributed to the drop in high-ozone days in the Houston area. Robert Talbot, professor of atmospheric chemistry, said that also should be true …
We examined the past 23 years of ground-level O3 data and selected meteorological parameters in Houston, Texas, which historically has been one of the most polluted cities in the United States. Both 1-h and 8-h O3 exceedances have been reduced significantly down to single digit yearly occurrences. We also found …
More than 40percent of Americans live where the air contains unhealthy levels of pollution, according to a newly released study. The American Lung Association, in their yearly State of the Air report, ranked the cleanest and most polluted metropolitan areas, noting the ways in which some cities are trying to …
More than four in 10 Americans - nearly 138.5 million people - live in counties where ozone or particle pollution levels make the air unhealthy to breathe, according to the American Lung Association's "State of the Air 2015" report released. The 16th annual national report card shows that improvement in …
Since the US Clean Air Act’s passage in the 1970s, there have been a steady stream of reports correlating exposure to air pollutants with a variety of health impacts. But in the early days, much of that information was too rudimentary to be of much use. Monitoring technology has improved …
California is suffering from "second-hand smog" drifting in from Asia and other places, researchers said on Tuesday, even as the state's prolonged drought has made air quality worse. About 10 percent of ozone pollution, the main ingredient in smog, in the state's San Joaquin Valley farm region comes from other …
