HARRISBURG, Pa. — A report released by the American Lung Association Thursday finds that air quality remains poor in the six-county Harrisburg-York-Lebanon metro area.
The 2022 "State of the Air" report determined that both daily and year-round measures of fine-particle pollution remains "poor," but the ozone/smog ranking was "moderate."
Fine-particle pollution and ozone/smog are two of the most harmful and widespread types of air pollution, the ALA said.
The metro area’s worst ranking was for daily spikes in fine particle pollution at 43rd worst in the country out of 221 metro areas ranked.
The “State of the Air” report is the Lung Association’s annual air quality “report card” that tracks and grades Americans’ exposure to unhealthy levels of ground-level ozone air pollution (also known as smog), annual particle pollution (also known as soot), and short-term spikes in particle pollution, over a three-year period.
This year’s report covers 2018-2020. See the full report at Lung.org/sota.
“The levels of particle pollution seen in the Harrisburg-York-Lebanon metro area can harm the health of all of our residents, but particularly at risk are children, older adults, pregnant people and those living with chronic disease," said Molly Pisciottano, Advocacy Director for the ALA. "Both ozone and particle pollution can cause premature death and other serious health effects such as asthma attacks, cardiovascular damage, and developmental and reproductive harm. Particle pollution can also cause lung cancer.
“Fortunately, the area did see continued posting of its best-ever results for the levels of ozone smog.”
Ground-level Ozone Pollution in the Harrisburg-York-Lebanon Metro Area
Compared to the 2021 report, the Harrisburg-York-Lebanon metro area experienced the same small number of unhealthy days of high ozone in this year’s report.
“State of the Air” ranked the Harrisburg metro area as the 117th most-polluted city for ozone pollution, which is comparable to its ranking of 119th worst in last year’s report.
Adams County was the sole county in the metro area with the highest weighted average number of unhealthy days for ozone, again reporting the metro area’s fewest days ever of 0.7 days (as both Adams and Lebanon County had done in last year’s report), and earning a “B” grade.
Particle Pollution in the Harrisburg-York-Lebanon metro area
The report also tracked short-term spikes in particle pollution, which can be extremely dangerous and even lethal.
The Harrisburg-York-Lebanon metro area’s short-term particle pollution worsened for a second year in a row in this year’s report, which means there were again more unhealthy days.
Dauphin County overtook Cumberland County for the worst performance for daily particle pollution in the metro area with a weighted average of 2.5 days (a “D” grade) in this year’s report.
The area is ranked 43rd worst for short-term particle pollution, having been in 42nd place last year.
The 2022 “State of the Air” found that year-round particle pollution levels in the area were very slightly worse than in last year’s report, but still continued to meet the national air quality standard.
York County continued as the worst performing county in the metro area, which was ranked 44th most polluted for year-round particle pollution, worse than its ranking of 56th worst last year.
The report found that nationwide, nearly 9 million more people were impacted by deadly particle pollution than reported last year. It also shows more days with “very unhealthy” and “hazardous” air quality than ever before in the two-decade history of this report.
Overall, more than 137 million Americans live in counties that had unhealthy levels of ozone or particle pollution. Communities of color are disproportionately exposed to unhealthy air.
The report found that people of color were 61% more likely than white people to live in a county with a failing grade for at least one pollutant, and 3.6 times as likely to live in a county with a failing grade for all three pollutants.
The addition of 2020 data to the 2022 “State of the Air” report gives a first look at air quality trends during the COVID-19 pandemic. Regardless of the shutdowns in early 2020, there was no obvious improvement.
