Experts say that in the past few weeks, in Maine the air has become cleaner, and the atmosphere has become noticeably clearer. These changes have been linked to the nationwide shutdown due to the COVID-19 pandemic, and more specifically to the significant decrease in emissions from transportation, such as airplanes and cars, and industrial operations. “There is data showing ozone levels are down noticeably in March 2020 over the same time period over the last 20 years,” said Don Darling, air monitoring section manager for the Maine Bureau of Air Quality of the DEP.
