Research to help shape efforts to reduce dangerous air pollution
By Bob Berwyn
Emissions from oil and gas production along the Colorado Front Range are a significant, measurable part of the region’s chronic summer ozone problem, scientists concluded after taking a close look at air pollution during an extensive research project in the summer of 2014.
Ozone levels in the area often spike above 70 parts per billion, a level deemed by the EPA to be dangerous to human health and to the environment, causing respiratory problems and damage to plants. About 17 ppb of that ozone are produced locally; about 3 ppb come from oil and gas industry emissions, according to a new study, published in the Journal of Geophysical Research.
A few more aerial shots left over in the Summit Voice archives, a little reminder (to myself) that airplane travel is a high-carbon activity. The world’s airlines are trying to grapple with the climate cost of their emissions, but so far, they have not made much progress, as you can read in this series of Summit Voice stories. Right now, the status is that an international air industry group is trying to develop its own self-policing scheme in order to avoid government regulations, but that effort is falling well short of what environmentalists want. The EPA is obligated under the Clean Air Act, to do something, but is moving much to slow. As a result, there’s a (big surprise) lawsuit to force the issue. Before any of that is resolved, air travelers always have the option of offsetting the carbon impacts of their own trip at Climate Care and other similar websites.
State fails to meet EPA standard set to protect public health; ozone problems to worsen with global warming

The modest steps taken by Colorado to try and improve air quality along the Front Range aren’t enough, according to the EPA. This week, the federal agency said the state has failed to meet air quality standards set to protect public health.
Officials prep for impacts to vulnerable populations
Michigan residents are likely to face a growing range of climate-related threats in coming decades, including respiratory diseases, heat-related illnesses and water- and vector-borne diseases, according to a new report from university researchers and state health officials.
Overall, the experts said that changing climate conditions like warmer temperatures and more frequent big rainstorms are an emerging public health threat in the state, where the average temperature has increased by anywhere from 0.6 to 1.3 degrees Fahrenheit since 1951. Average annual precipitation has increased by 4.5 percent during that period. Continue reading “Michigan eyes climate-related public health threats”→
Kids living close to highways suffer from reduced lung function
Despite increased efforts to control pollution from vehicles and industrial sources, young children are still being exposed to harmful levels of particulates that impair lung function.
A long-term health study shows that, by age eight, the lung function of children living within 100 meters of a major roadway was on average 6 percent lower than that of children living 400 meters or more away.
The study was one of the first to examine childhood exposure to air pollution after big improvements to urban air quality in the 1990s, explained lead author Dr. Mary B. Rice. The findings are published the American Journal of Respiratory and Critical Care, a journal of the American Thoracic Society. Continue reading “Highway air pollution still a big public health threat”→
