BOSTON, MA | April 24, 2019
The American Lung Association’s 2019 "State of the Air" report found 8 out of 12 reporting counties in the Commonwealth of Massachusetts recorded more bad ozone days, resulting in reduced grades compared to the 2018 report. The annual air quality "report card" tracks Americans’ exposure to unhealthful levels of ozone or particle pollution, both of which can be deadly.
"Massachusetts residents should be aware that we’re breathing unhealthy air, driven by emissions from power plants and extreme heat as a result of climate change, placing our health and lives at risk," said Elizabeth Hamlin-Berninger, Director of Advocacy in Massachusetts for the American Lung Association. "In addition to challenges here in Massachusetts 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.
Compared to the 2018 report, Massachusetts counties did considerably worse, reporting more bad air days for ozone. The counties of Barnstable Bristol, Hampden and Hampshire decreased one or more grades, earning F’s in the 2019 report. Dukes, Plymouth, Suffolk and Worcester also lost grades, earning them C’s and D’s. All together, the counties recorded a total of 97 combined "orange" and "red" bad ozone days from 2015-2017, compared to 59 bad ozone days from 2014-2016.
The counties of Essex, Franklin, Middlesex and Norfolk maintained their grades from last year, despite the overall trend of increased bad air days.
"Ozone especially harms children, older adults and those with asthma and other lung diseases," said Hamlin-Berninger. "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.
For Massachusetts, a silver lining in the report highlights a slight decrease in year-round particle pollution levels in all but 3 counties (Berkshire, Hampden and Suffolk), while all counties reported levels in line with national standards and maintained passing grades. Pittsfield MA made the Top 25 list for cleanest year round particle pollution and short term particle pollution. This follows the nationwide trend, showing progress 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 Hamlin-Berninger. "Several counties within the Boston-Worcester-Providence metro area ranked on the cleanest counties list for particle pollution – both long and short-term."
"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 all of Massachusetts’ reporting counties continue to maintain short-term particle pollution in line with national standards, resulting in A grades.
While the report examined data from 2015-2017, this 20th annual report online provides information on air pollution trends back to the first report.
