Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new work led by the National Center for Atmospheric Research (NCAR). Ozone formation. Even short periods of unhealthy ozone levels can cause local death rates to rise. Scenario A2 and RCP 8.5.

The US Environmental Protection Agency (EPA) announced $5,959,842 million in research funding to nine institutions to improve air quality models used to simulate ozone, particulate matter (PM), regional haze, air toxics, and emerging pollutants. It will also inform the development of strategies for improving air quality.

VOCs and nitrogen oxides react with sunlight to form ground-level ozone, the main component of smog. The team also observed chemical transformations of the emissions from Decatur, including formation of new particles, nitric acid, peroxyacyl nitrates, aldehydes, ozone and sulfate aerosol.

They found that reductions in ground ozone during this 35-year period resulted in $600 million in increased production annually by the early 2010s. Another difference is that some grains can be annually modified to withstand greater heat and even higher ozone levels in the air. An open-access paper on the work appears in Nature Food.

A University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack the oil so it can be removed by sand filters. The ozone in the bubble attacks certain pollutants because it is a strong oxidant.

These results show that meeting future air quality standards for ozone pollution will be more challenging than previously thought.
