People exposed to fine particle (PM2.5) and ozone pollution are at increased risk of suffering out-of-hospital cardiac arrests, according to a recent Finnish study. Cardiac arrest is more likely within 24 hours after exposure to PM2.5 and up to several days after exposure to ozone. Previous studies have already linked air pollution with sudden events causing cardiac (heart) arrest, when the heart ...
‘Critical levels’ of ozone exposure for plants, above which significant adverse effects may occur, are currently calculated by examining ozone’s impacts on only a small number of species. However, researchers have now compared this measure with a new approach which examines all species in a group, and defines the critical levels as the concentration at which 5% of species are ...
High summer temperatures combined with air pollution can cause ground-level ozone to form, which has serious effects on health, especially for older people or children, or those with asthma and other breathing problems. The European Environment Agency (EEA) presents some useful information on protecting your health from ground-level ozone this summer. To date, the highest concentrations ...
A recent study has calculated crop losses as a result of surface ozone pollution. The study suggests that future earnings will be significantly reduced by ozone damage to crops, especially for some developing and agriculture-dependent countries. Surface ozone is an air pollutant that forms as a result of chemical reactions between other pollutants, particularly emissions from motor vehicles and ...
A new study has estimated that nitrogen oxide (NOx) and harmful ozone levels will fall significantly in Europe, by 2030, if all current and planned air quality legislation is implemented. The co-beneficial effects of climate change policies could also reduce levels of these air pollutants by a further 40%. Conducted under the EU projects CityZen, PEGASOS and ECLAIRE1, the research set out ...
Unusually high temperatures this summer may be contributing to poor air quality in many European cities. Thresholds to protect health from ground-level ozone have been exceeded across Europe in recent weeks, according to preliminary data reported to the European Environment Agency (EEA). Ozone pollution has serious effects on health, especially for older people and children, or those with ...
Exposures of less than 24 hours to current levels of ground-level ozone in many areas are likely to contribute to premature deaths, finds a new US National Research Council report. Ozone, a key component of smog, can cause respiratory problems and other health effects. In addition, evidence of a relationship between exposures of less than 24 hours and mortality has been mounting, but ...
EMSL Analytical provides complete ozone testing services to shield people from unnecessary exposure and to help manufacturers test products and equipment. Ozone consisting of three oxygen atoms and is beneficial in the upper atmosphere due to its ability to protect the planet from harmful radiation. However, tropospheric ozone, also known as low level ozone, is recognized by the World ...
Bonded activated carbon filters from UltraViolet Devices (UVDI) provide solutions for ozone removal in California and cities nationwide. The American Lung Association recently released their annual report, State of the Air 2010. The report reveals ozone and particulate pollution levels found at monitoring sites across the country. The California cities of Los Angeles, Long Beach and ...
Summer heat is here, and that means it is more important than ever for people with asthma or other respiratory ailments to pay close attention to the air quality where they live. Like the weather, air quality can change from day to day or even hour to hour. During the summer when ozone levels rise, the number of people with asthma related symptoms admitted to hospitals and emergency rooms ...

For the millions of Americans with respiratory allergies, asthma or COPD, their home or office can sometimes be the source of allergens that can trigger or aggravate their condition. According to the American College of Allergy, Asthma & Immunology, nasal allergies are estimated to affect close to 50 million people in the United States. Allergic rhinitis alone results in more than ...
Working closely with states and tribes, the U.S. Environmental Protection Agency (EPA) is identifying areas that meet or do not meet the 2008 air quality standards for ground-level ozone, known as smog. The agency’s approach to implementing these standards will improve air quality, protect public health, increase certainty for states and tribes, maximize flexibilities and minimize the ...
WASHINGTON, DC (ENS) - Today, a federal appeals court struck down the Bush administration’s rules for ensuring public health is protected from ground level ozone, or smog. The panel of the U.S. Court of Appeals for the DC Circuit ruled that some of the U.S. Environmental Protection Agency's 2004 ozone requirements were too weak to conform with the Clean Air Act, and that the agency ...
The environmental consulting experts at EC2 provide indoor air quality (IAQ) testing services for ozone and other contaminants to minimize health risks. Tropospheric ozone, also known as low level ozone, is recognized by the World Health Organization (WHO) and the U.S. Environmental Protection Agency (EPA) as a pollutant. It can be generated in populated areas by sunlight reacting ...
Health and environmental advocates filed a lawsuit Tuesday challenging the U.S. Environmental Protection Agency's refusal to adopt stronger standards for ground-level ozone proposed by the agency's own scientists. The American Lung Association, Natural Resources Defense Council, Environmental Defense Fund, the National Parks Conservation Association, and the Appalachian Mountain Club are taking ...
Now that the summer heat is here it’s a good time to pay attention to your local air quality. Like the weather, air quality can change from day to day or even hour to hour and it can affect how you live and breathe. When the summer heat builds, ground-level ozone levels increase - - and ground-level ozone, often called smog, is a contributor to the onset or the exacerbation of an asthma ...
"A warming world with violent storms holds many unpleasant surprises" said Durwood Zaelke, President of the Institute for Governance and Sustainable Development (IGSD). "Recent research now suggests that this may include damage to the protective ozone shield, which protects us from harmful ultraviolet radiation that causes skin cancer, cataracts, suppresses the human immune system, and damages ...
The U.S. Environmental Protection Agency has announced that it is taking final action to approve the state of North Carolina’s request to redesignate the Charlotte area to attainment of the 1997 8-hour ozone standard. This action is based on air quality monitoring data for the three-year period of 2008, 2009, and 2010 that meets the standard. The area continues to attain this standard. On ...
As well as contributing to the greenhouse effect, aircraft emissions have an important impact on air quality and human health. This study, which quantified the effect of civil aviation emissions across the globe, suggests they could be responsible for 16 000 premature deaths every year, at an annual cost of over €18 billion. The air quality costs of aviation were similar to its climate ...
