Latest Tropospheric ozone Stories

GUELPH, ON, June 22 /PRNewswire-FirstCall/ - BIOREM Inc. ("Biorem" or "the Company") (TSX-V: BRM) today announced that it has received an order for its advanced biological-based volatile organic compounds (VOC) abatement system, totaling just over $500,000. VOCs are emitted primarily from solvents and fuels and react in the atmosphere to form ground-level ozone. This system will be used to remove VOC emissions from an EPA designated "ozone-non-attainment area" in the United States where...

The Berks/Lehigh region includes Berks, Lehigh and Northampton counties;...

A new study identifies cattle feed as a possible culprit in the long-standing mystery of why California's San Joaquin Valley "” a moderately-populated agricultural region "” has higher levels of ozone (one of the main ingredients in smog) than many densely-populated cities. The report, which explains how fermented cattle feed works with automotive exhausts in forming ozone, is in ACS' Environmental Science & Technology, a semi-monthly journal.Michael Kleeman and colleagues note that...

Warren Kindzierski, University of Alberta researcher in the School of Public Health, says people living in the communities of Fort McMurray, Fort Mckay and Fort Chipewyan should feel confident that the air they are breathing is safe.Kindzierski's research has found that, despite ongoing development, it's apparent that there is little or no pattern to the changes in concentrations of various air pollutants across the oil sands region over the past 10 years.This study came about when...

Surface ozone levels in the south west of the Iberian Peninsula usually exceed the protection threshold established by EU regulations for people and plants in spring and summer, according to data gathered between 2000 and 2005 by four measuring stations in Huelva, one of them next to the Doñana National Park.The limits established to protect human and plant health by the European Directive on ozone are usually exceeded from April onwards, especially during the summer, in the south west of...

WASHINGTON, March 26 /PRNewswire-USNewswire/ -- The American Public Health Association this week petitioned the U.S. Environmental Protection Agency to adopt stronger, more protective standards to safeguard the health of the public from ground-level ozone. In a letter to EPA Administrator Lisa Jackson, APHA and 17 other public health organizations applauded EPA's decision earlier this year to reconsider the standards it set in 2008. The groups urged EPA to go farther and set standards that...

EDF Testifies 20 Million+ Residents in South Coast, San Joaquin Valley Would Benefit SACRAMENTO, Calif., Feb. 4 /PRNewswire-USNewswire/ -- Environmental Defense Fund testified today that strengthening the National Ambient Air Quality Standard (NAAQS) for ozone pollution from 75 to 60 parts per billion (ppb) would reduce premature death rates by 60-fold and reduce asthma cases 50-fold, according to analyses by the Environmental Protection Agency (EPA). The testimony is being given at an EPA...

Stronger Standards will Help Reduce Asthma Attacks, Hospitalizations and premature deaths SACRAMENTO, Calif., Feb. 1 /PRNewswire-USNewswire/ -- The American Lung Association, Breathe California, Coalition for Clean Air, Environmental Defense Fund and the Sierra Club will hold a joint press conference in support of the U.S. Environmental Protection Agency (EPA) proposal to strengthen the national limits for ozone "smog" pollution. The organizations are calling on the EPA to enact the most...

Researchers in Freiburg have developed a highly-sensitive, miniaturized mobile ozone sensor which can be used not only in air, but also in water and in the vicinity of explosive gases.The Fraunhofer Institute for Applied Solid State Physics IAF in Freiburg is developing improved chemical sensors that are not prohibitively expensive. One particularly important area of application involves the regular measurement of ozone content in air and other media. This gas is a powerful oxidizing agent...
