Louisiana Air Quality Improved for Ozone, Particle Pollution, Finds 2019 ‘State of the Air’ Report

–The American Lung Association’s 2019 “State of the Air” report found several Louisiana cities earned improved rankings for the nation’s most widespread air pollutants. The annual air quality “report card” tracks Americans’ exposure to unhealthful levels of ozone or particle pollution, both of which can be deadly. The 20th annual report found that Houma, Thibodaux, Monroe and Ruston all experienced zero unhealthy air days and were named to the cleanest cities list for ozone pollution.

Baton Rouge however is ranked 35th in the nation for the most polluted city in ozone despite recording its fewest-ever unhealthy air days.

New Orleans, Metairie, Shreveport, Bossier City, Minden, Alexandria, Houma, Thibodaux, Lake Charles, Jennings, Lafayette, Opelousas, and Morgan City were added to the cleanest cities list for short-term particle pollution 

For the fourth year in a row, the New Orleans metro area improved again to its fewest unhealthy air days ever in ozone pollution. The metro area also improved in year-round particle pollution and recorded its best levels. Additionally, New Orleans experienced no unhealthy air days for short-term particle pollution for the fifth consecutive report.

“Louisiana residents should be aware that we’re breathing unhealthy air, driven by heat as a result of climate change, placing our health and lives at risk,” said American Lung Association Director of Advocacy, Ashley Lyerly. “In addition to challenges here in Louisiana, the 20th-anniversary ‘State of the Air’ report highlights that more than 4 in 10 Americans are living with unhealthy air, and we’re heading in the wrong direction when it comes to protecting public health.”

This year’s report covers the most recent quality-assured data available collected by states, cities, counties, tribes and federal agencies in 2015-2017. Notably, those three years were the hottest recorded in global history.

Each year the “State of the Air” provides a report card on the two most widespread outdoor air pollutants, ozone pollution, also known as smog, and particle pollution, also called soot. The report analyzes particle pollution in two ways: through average annual particle pollution levels and short-term spikes in particle pollution. Both ozone and particle pollution are dangerous to public health and can increase the risk of premature death and other serious health effects such as lung cancer, asthma attacks, cardiovascular damage, and developmental and reproductive harm.

Ozone Pollution in Louisiana

Compared to the 2018 report, Baton Rouge, New Orleans, Houma, Thibodaux, Monroe, and Ruston experienced fewer unhealthy days of high ozone in this year’s report.

Baton Rouge reduced its average unhealthy ozone days in 2015-17 to its best-ever but still earns an F grade. East Baton Rouge Parish has had the highest weighted average number of days – 6.7 a drop from last year’s 7.3 days, and fewest-ever.

“Ozone especially harms children, older adults and those with asthma and other lung diseases,” said Lyerly. “When older adults or children with asthma breathe ozone-polluted air, too often they end up in the doctor’s office, the hospital or the emergency room. Ozone can even shorten life itself.”

This report documents how warmer temperatures brought by climate change make ozone more likely to form and harder to clean up. This year’s report showed that ozone levels increased in most cities nationwide, in large part due to the record-breaking global heat experienced in the three years tracked in the report.

Particle Pollution in Louisiana

The 2019 report also found year-round particle pollution levels significantly lower than the 2018 report. Nationwide, the best progress in this year’s report came in reducing year-round levels of particle pollution.

“Particle pollution is made of soot or tiny particles that come from coal-fired power plants, diesel emissions, wildfires and wood-burning devices. These particles are so small that they can lodge deep in the lungs and trigger asthma attacks, heart attacks and strokes, and can even be lethal,” said Lyerly. “Year-round particle pollution levels have dropped thanks to the cleanup of coal-fired power plants and the retirement of old, dirty diesel engines.”

“State of the Air” 2019 also tracked short-term spikes in particle pollution, as these can be extremely dangerous and even lethal. The report found that New Orleans, Baton Rouge, Alexandria, Houma, Thibodaux, Lafayette, Opelousas, Morgan City, Lake Charles, Jennings, Monroe, Ruston, Shreveport, Bossier City, and Minden had fewer days when short-term particle pollution reached unhealthy levels.

While the report examined data from 2015-2017, this 20th annual report online provides information on air pollution trends back to the first report.
