China study connects ozone pollution to cardiovascular health

Green Car Congress

Exposure to ozone, long associated with impaired lung function, is also connected to health changes that can cause cardiovascular disease such as heart attack, high blood pressure and stroke, according to a new study of Chinese adults. They monitored indoor and outdoor ozone levels, along with other pollutants.

Study associates long-term exposure to air pollution with increasing emphysema

Green Car Congress

Long-term exposure to ambient air pollutants, especially O 3 (ozone), is significantly associated with increasing emphysema, according to a new study led by the University of Washington, Columbia University and the University at Buffalo. The annual averages of ozone levels in study areas were between about 10 and 25 ppb.

Study finds that current approach to limiting wintertime pollution may initially backfire

Green Car Congress

The processes that create ozone pollution in the summer can also trigger the formation of wintertime air pollution, according to a new study from researchers at the University of Colorado Boulder and NOAA, in partnership with the University of Utah.

Air Quality: Easy to Measure, Tough to Fix

Cars That Think

I had the monitor installed, working, and connected to the Airthings app less than 10 minutes after it arrived at my doorstep, in June. Ionization can itself create ozone. The state of California has banned such ozone generators entirely. an activated carbon filter can remove volatile organic compounds and ozone from the air.

Study finds changes in the Arctic sea ice cover may be driving changes in atmospheric chemistry

Green Car Congress

The connection between changes in the Arctic Ocean’s ice cover and bromine chemical processes is determined by the interaction between the salt in sea ice, frigid temperatures and sunlight. Bromine also can remove ozone from the lowest layer of the atmosphere, the troposphere.

California ARB and NOAA Collaborating in $20M Research on Interaction of Air Pollution and Climate Change; One Atmosphere Approach

Green Car Congress

Although separate programs are in place to research and manage both air quality and climate change effects, these problems are not separate and in fact are intimately connected. The complex roles that ozone and aerosols play in the atmosphere provide examples of such trade-offs. 2010 CalNex Science and Implementation Plan.
