Ozone levels across much of North America and Europe dropped significantly between 2000 and 2014. People living in parts of southern Europe, South Korea and southern Japan and China also experienced more than 15 days a year of ozone levels above 70 ppb. Trends in daily maximum ozone levels (known as 4MDA8) at urban and non-urban sites.

They found that the increase in ozone burden due to the spatial distribution change slightly exceeds the combined influences of the increased emission magnitude and global methane. Based on their findings, they suggested that emission increases in Southeast, East and South Asia may be most important for the ozone change.

Researchers at the University of Colorado, Boulder and the National Renewable Energy Laboratory (NREL) modeled the emissions impact had plug-in hybrid electric vehicles (PHEVs) replaced light duty gasoline vehicles in the Denver, Colorado area in summer 2006. VOC emissions would have been reduced by 57 tpd.

More than half of all air-quality-related early deaths in the United States are a result of emissions originating outside of the state in which those deaths occur, MIT researchers report in a paper in the journal Nature. Now it’s looking like other emissions sectors are becoming important. That wasn’t really possible before.

NOVEMBER 17, 2009

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.

New airborne measurements downwind from an Archer Daniels Midland fuel ethanol plant in Decatur, Illinois, show that ethanol emissions are 30 times higher than government baseline estimates. VOCs and nitrogen oxides react with sunlight to form ground-level ozone, the main component of smog. That is where this study fits in.
