PORTLAND, Maine – The news for Maine is both good and bad in the latest State of the Air report released by the American Lung Association.
The figures are the most current quality-assured nationwide data on levels of ozone and particle pollution.
Bangor ranked among the four cleanest cities in the nation.
Dr. Marguerite Pennoyer, a board member of the American Lung Association in Maine, says Bangor experienced no unhealthy air days for ozone or particulates during the cycle involved.
"In contrast, Cumberland and York County, our southern parts of the state, had 14 days of unhealthy ozone levels," she relates.
Cumberland got a grade of C, York a D, while Penobscot County received an A.
The report shows the nation's air quality worsened in 2010-2012, but overall is cleaner than a decade ago.
According to the Division of Population Health, Maine has some of the highest rates of asthma in the country.
Approximately 10 percent of Maine adults currently have asthma compared to 7.8 percent nationally. Pennoyer treats many of them.
"Anyone who deals with respiratory disease in Maine can tell you that any time we have poor air quality days the number of calls, the number of emergency department visits increase," she says.
Janice Nolen of the American Lung Association says she's concerned about climate change and how a warmer planet is going to affect air quality.
"If you've got more heat and that's what we're seeing with climate change, you're going to have more ozone, you're going to have the likelihood that you are going to have higher levels than you would otherwise,” she says. “And it's going to make it harder to clean up, and make it more challenging for us to reduce the ozone that we've got."
Pennoyer points out part of the problem for Maine starts to the west and south.
"We are the tail-pipe of New England, and with all these beautiful Down East winds we get everything from the Midwest on over,” she explains. “So we really do see more than our fair share and much of it not produced here."

New research from the University of New Hampshire could help dairy farmers increase profits while reducing their effect on the climate.
Scientists said adding a plant-based essential oil blend to cow feed can improve a cow's digestion and reduce the release of methane, a potent greenhouse gas.
Andre Brito, associate professor of dairy cattle nutrition and management at the University of New Hampshire, said the findings are especially true for pasture grazing cows and shows a happy cow makes for a healthier environment.
"If those animals are provided those conditions, they'll be more productive," Brito pointed out. "Then the amount of methane that's being emitted by those animals is diluted because they're producing more product."
Brito reported adding the plant oils led to a more than 6% increase in milk production, which is good news for the majority of New Hampshire dairies, especially small to mid-size operations with smaller profit margins and higher equipment costs.
Still, Brito noted the research findings could translate to larger, industrial-size dairies. The factory farms often hold thousands of cows, generating significant methane emissions through their hearty burps and manure, which is often stored in large, polluting lagoons.
Brito acknowledged although the plant-based oils are readily available for use, farmers must weigh the economic benefits and overall environmental impact.
"Any investment that the farmers would make in a product has to be tied to economics," Brito stressed. "Even though farmers overall, they are conscious about the environment and they want to make sure that there is less carbon, nitrogen footprint out of their farms."
Brito's research was conducted on cows as they transitioned from the winter indoor-feeding schedule to eating their favorite plants in the pasture, a diet change which can increase the cow's emissions.
Brito added he hopes the research can help farmers better understand when to add the oils to the cow feed to potentially reduce the cow's overall climate effect.

State officials in Maine are highlighting apprenticeships as a way to earn a living wage and contribute to the state's growing green economy.
They'll kick off the first-ever Youth Apprenticeship Week by exposing high school students to the numerous ways they can learn and earn in offshore wind energy development, passive home construction, aquaculture, and more.
Maine Department of Labor Apprenticeship Program Manager Kristine McCallister said about 90% of apprentices choose to stay with their employer after their training is complete.
"Apprentices have a mentor and they're earning wages and they're earning pay increases as they go," said McCallister, "so it's a really great way to attract talent to Maine and to keep talent here."
McCallister said apprentices will earn $300,000 more over their lifetime. The state aims to add 75,000 more workers to the economy over the next five years by growing career training pipelines.
A report by the Maine Labor Climate Council finds the state can create tens of thousands of jobs by building a zero-carbon transportation system.
Workers will be needed to install EV charging stations, electrify school bus fleets, and potentially build a high-speed rail line from Bangor to Boston.
McCallister said new Mainers, like those studying with Portland Adult Education, are using apprenticeships to fill these roles and other clean-energy jobs.
"Those pre-apprentices just graduated and have interviewed with some of our apprenticeship programs," said McCallister, "so we're really hoping they're going to help feed that pipeline as this economy is booming in Maine in terms of the renewable-energy sector."
McCallister said some companies are even offering on-the-spot interviews and job offers this week. All apprenticeship events are listed on the Department of Labor's website.

Climate watchers are predicting this summer's temperatures may set records, which could aggravate some medical conditions.
A 30-year study of health records from more than 200 countries and territories suggests a connection between stroke and climate change. The online publication "Neurology" reported the growing number of global deaths and disabilities from strokes are linked to -- but not caused by -- climate change.
Dr. Ann Jones, stroke neurologist at Indiana University Hospital, said when the body feels extreme heat and sweat evaporates, hypercoagulation, or blood thickening, occurs, which increases the chance for blood clots. Winter weather can also produce an instinctive response.
"The cold makes us kind of react with our fight-or-flight kind of drive, and it makes our blood vessels close down or vasoconstrict," Jones explained. "That can raise blood pressure up and that can predispose you to stroke."
Jones noted an ischemic stroke involves a clogged artery preventing blood from flowing to brain tissue. A ruptured artery during a hemorrhagic stroke causes blood to travel outside the artery wall into the brain tissue.
The Centers for Disease Control and Prevention reported almost 43% or 3,500 per 100,000 Hoosiers died from a stroke in 2021. Indiana ranks 34th in the nation for the rate of strokes.
The Yale Center on Climate Change and Health found heat can increase the risk of a stroke. Recent global burden-of-disease studies found 2 to 5 million deaths per year are linked to extreme temperatures globally. And climate change can also indirectly impact health through poor water quality, air pollution and increased spreading of infectious diseases.
Jones maintained good health is a start toward prevention and recommends the Mediterranean diet; consuming less red meat for optimal well-being and getting 30 minutes of exercise five times per week.
"Some things are out of our control," Jones acknowledged. "But just taking care of yourself in the ways that we can; focusing more on vegetables, fish, and staying hydrated, working on blood pressure with that reduced goal of less than 130 over 80."
The study indicated more research could identify the impact of temperature change on stroke as a way to address health inequalities including the burning of fossil fuels, deforestation and industrial processes.
