The American Lung Association’s 2018 “State of the Air” report found Boston ranked as the 47th most polluted city in the nation for ozone, which is significantly improved from last year’s ranking at 37. Compared to the 2017 report, Boston, along with the counties of Bristol, Essex and Suffolk cut both ozone and year-round particle pollution. This is in spite of a trend seen across the nation of higher ozone pollution levels.
“The 2018 ‘State of the Air’ report finds that the Boston metro area reported some of the lowest pollution levels on record for 2014-2016. We are glad to see the continued improvement, and hope to sustain this momentum in improving air quality for Massachusetts residents,” said Jeff Seyler, Chief Division Officer of the American Lung Association. “Across the nation, the report found continued improvement in air quality, but still, more than four in 10 Americans – 133.9 million – live in counties that have unhealthful levels of either ozone or particle pollution, where their health is at risk.”
The trends reported in this year’s report, which covers data collected by states, cities, counties, tribes and federal agencies in 2014-2016, reflect the ongoing challenges to reduce each pollutant in the changing political and outdoor climate.
“Improving grades are great, but we have to remember that all it takes in one bad air day to send a child with asthma or an elderly person to the emergency room,” said Michael Seilback, Vice President, Public Policy & Communications for the American Lung Association, Northeast Region “The Lung Association in Massachusetts calls on our members of Congress to defend the Clean Air Act, currently under threat from those who want to weaken this effective public health law. We also call on the U.S. Environmental Protection Agency to implement and enforce the law instead of trying to roll back major safeguards like the Clean Power Plan and cleaner cars, both steps that help us fight climate change and reduce air pollution.”
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 Massachusetts
Compared to the 2017 report, only the county of Hampshire experienced a drop in grade for ozone from a C to a D, caused by the 2 additional high ozone days. Hampden County recorded the worst ozone in the state, also recording 2 additional high ozone days with a weighted average of 3.2 between 2014-2016 as opposed to 2.3 from 2013-2015
“Ozone especially harms children, older adults and those with asthma and other lung diseases,” said Seilback. “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 warmer temperatures in 2016, the second hottest year on record in the U.S. Over the past decades, ozone pollution has decreased nationwide because the nation has cleaned up major sources of the emissions that create ozone, especially coal-fired power plants and vehicles.
Particle Pollution in Massachusetts
The 2018 report also found year-round particle pollution levels lower than the 2017 report. Suffolk recorded the worst year round particle pollution at 7.2, although the county did show improvement from last year’s value of 7.7. 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 Seilback. “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” 2018 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 had maintained short-term particle pollution in line with national standards, resulting in Passing grades.
While the report examined data from 2014-2016, this 19th annual report provides online information on air pollution trends back to the first report covering 1996-1998.
