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.

Using Ozone-Generated Bubbles to Remove Oil Sheen and Contaminants from Water

Green Car Congress

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.

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. —Jin et al.

Colorado has voted to approve a new standard on the adoption of electric vehicles (EVs), with an additional goal set for 2032 and new guidance for increasing EV sales beginning in 2027. In 2019, Colorado also joined nine other states in adopting standards to accelerate the rollout of EVs in their regions.

Perhaps surprisingly, this reduction in cross-state pollution also appears to be related to electric power generation: In recent years, regulations such as the Environmental Protection Agency’s Clean Air Act and other changes have helped to significantly curb emissions from this sector across the country. and/or ozone.

They found that levels of pollutants that can contribute to the formation of ground-level ozone, or smog, have failed to continue a fairly steady decline as estimated by the US Environmental Protection Agency. These results show that meeting future air quality standards for ozone pollution will be more challenging than previously thought.
