Agencies are raising awareness about air quality across the country this week.

Led by the U.S. Environmental Protection Agency, Air Quality Awareness Week is highlighting the effects of poor air, with a special focus on wildfires and smoke today.

Julie Fox, environmental epidemiologist for the Washington Department of Health, said unfortunately, the people who are sensitive to wildfire smoke is long, starting with people with preexisting conditions like asthma and cardiovascular diseases.

"It also includes children, people over 65 years of age, pregnant people, outdoor workers, people of color, tribal and Indigenous people, people with low incomes and others who are all at increased risk for all different reasons that we're concerned about," Fox outlined. "Those are really the groups where we want to focus on taking steps to protect health."

Fox noted people who are not as sensitive to smoke might see milder symptoms, such as sore throat, headache, fatigue and itchy eyes. Wildfire season typically takes place between midsummer and early fall in the Northwest.

Fox stressed when smoke is bad, people should be ready to adjust their days.

"When we look at the air quality index that indicates the hazard level of the air quality, we start by recommending just avoiding outdoor exercise," Fox explained. "Then as it increases, we recommend going indoors and also really taking steps to ensure that the indoor air is clean."

Fox added right now is a good time for people to purchase items to ensure they have clean indoor air because it can be difficult to do so when the outdoor air gets smoky.

On Tuesday, the focus of air quality awareness week is on asthma. May 7, is World Asthma Day.

Agencies are raising awareness about air quality across the country this week.

Led by the U.S. Environmental Protection Agency, Air Quality Awareness Week is highlighting the effects of poor air, with a special focus on wildfires and smoke today.

Travis Knudsen, public affairs manager for the Lane Regional Air Protection Agency, said small particles known as PM 2.5 in wildfire smoke can cause itchy eyes, coughing and other short-term respiratory problems.

"If you are someone who already suffers from respiratory issues, like you have asthma, it makes those acute symptoms that much more challenging and potentially problematic from a health perspective," Knudsen explained.

Knudsen said PM 2.5 particles can penetrate deep into the lungs. He also noted the Northwest is seeing more wildfires and his agency attributes it to climate change.

Smoke from wildfire season is at its peak in the Northwest starting around midsummer and lasting through early fall. Knudsen advised people to check the air quality index during smoke season, and pointed out people might need to reschedule their outside activities -- such as running or working out -- based on the air quality.

"Maybe when our quality is bad we reconsider those outdoor activities and instead just stay inside with a HEPA air purifier running so we are not being exposed to that harmful pollution from wildfire smoke," Knudsen suggested.

On Tuesday, the focus is on asthma. May 7 is World Asthma Day.

Most school and transit buses on the nation's roadways these days are still powered by diesel engines but in Wisconsin and elsewhere, there is hope about the push to switch to electric fleets.

The city of Racine has made headlines in recent years for leveraging federal funds to add more electric buses operated by its transit agency. Through the Bipartisan Infrastructure Law, school systems such as the Palmyra-Eagle district have used federal grants to buy a handful of buses fitted with such technology.

Susan Mudd, senior policy advocate for the Environmental Law and Policy Center, a Midwest-based advocacy group, said it is encouraging to see the activity, knowing benefits will come with it.

"The children or the riders on buses, including the drivers, will experience zero tailpipe emissions," Mudd pointed out. "Which they now do, because fumes, unfortunately, often get circulated into buses."

The new models also prevent harmful emissions from floating through neighborhoods, especially when buses are idled. Mudd noted it has a positive effect on human health, as well as mitigating climate change, with transportation making up nearly 30% of U.S. carbon emissions. But even with federal support, she acknowledged there are still upfront cost barriers in securing electric buses.

Mudd added implementing charging stations for larger electric bus fleets can be more intensive than infrastructure for passenger models.

"It definitely requires more equipment," Mudd said. "(It) may require transformer upgrades and that is more costly."

Organizations like hers are appealing to utilities to help make the infrastructure more accessible to schools and transit agencies. Once they get past the initial expenses, supporters said the efforts help schools and municipalities reduce their fuel costs.

In late 2022, Wisconsin received more than $25 million in federal support to replace 65 diesel school buses around the state with electric ones.

Groups concerned about air pollution and public health are asking the city councils of Long Beach and Los Angeles and their respective Harbor Commissions to pass major restrictions on air pollution from ships.

The "Ports for People" ordinance would require agencies to take steps to reduce pollution from cargo ships by 50% from 2019 levels by 2030, and to achieve 100% zero-emission shipping at the ports by 2040.

Dawny'all Heydari, climate campaign advocacy manager for the nonprofit Pacific Environment, said ships running on fuel oil and Liquefied Natural Gas need to be phased out.

"These fuels are filled with asthma and cancer-causing pollutants that are contaminating communities like my own in Long Beach with shorter life expectancy and childhood asthma," Heydari pointed out. "We're advocating for a transition to zero-emission fuels to power shipping."

This week, advocates gathered signatures in favor of the ordinance at Cal State Long Beach and presented them to the Long Beach Harbor Commission. They hope to spur the shipping industry to switch to greener alternatives, such as battery electrification, wind-assist propulsion and "green hydrogen" fuel cells.

Heydari noted Pacific Environment has had positive conversations with some members of the Long Beach City Council and hopes they will take bold action in the future.

"When California cities institute these kinds of regulations, it forces the industry to evolve because the industry is primarily concerned about its own profits," Heydari asserted. "It's not really primarily concerned about sustainability, nor public health."

A 2019 study from the City of Long Beach found the average life expectancy in West Long Beach next to the port is eight years shorter than the average in Los Angeles County.

A 2021 study by the California Air Resources Board found fuel pollution from pandemic-era cargo ship congestion at the San Pedro Ports caused an increase in particulate matter emissions equivalent to 100,000 semi tractor-trailers per day.
