Recent data ranks Columbus as the most polluted major city in the U.S., highlighting concerns about common pollutants, like smog and vehicle emissions.

New research links these pollutants to the risks for dementia.

Dr. Alan Cronemberger Andrade, in the postgraduate program in neurology and neuroscience at the Federal University of São Paulo, said the study of more than 2,500 adults showed a need for more local research on air pollution's effect on cognitive health.

"We see that there is really evidence linking air pollution to cognitive decline and dementia risk," Cronemberger Andrade observed.

He pointed out stroke and cardiovascular diseases, such as ischemic heart disease and atrial fibrillation are other key links between air pollution and dementia, and vascular issues also contribute to the connection.

In Ohio, the most recent figures, from 2019, indicate about 591,000 people over age 45 have some form of dementia.

Dr. Fabricio Ferreira de Oliviera, executive medical director of Elysian Clinica Medica and Neurologia at the Federal University of São Paulo, said one component of the study looked at people's proximity to high-pollution sources.

"If they live near a highway or near a very polluted area, they can have more cognitive impairment than those who live farther from those regions," Ferreira emphasized.

He suggested conducting ongoing studies to determine if reducing air pollution could lower the risk of dementia and cognitive decline, and better overall health outcomes.

Earlier this month, the Federal Highway Administration stopped new funding for electric vehicle charging stations under the National Electric Vehicle Infrastructure program.

Through the Bipartisan Infrastructure Law, the program allocated $5 billion over five years to all U.S. states, D.C., and Puerto Rico. Michigan was set to receive $110 million for fast-charging stations along key routes.

Chase Attanasio, policy manager for the advocacy group Clean Fuels Michigan, said despite the cuts, EV charging ports expansion plans in the state are affected but not aborted.

"The utility companies in Michigan have been and will continue to invest heavily in EV infrastructure deployments in their service territories that support a variety of different use cases," Attanasio pointed out. "And there are state programs that will continue to support EV charger deployments across the state."

The federal government will allow existing contracts to proceed with reimbursements until new guidance is issued.

There are currently 3,700 public charging stations around the Great Lakes State and the goal is to deploy 100 thousand by 2030. Attanasio believes Michigan has an opportunity to step up and take the lead in the clean mobility sector, despite uncertainties.

"Increasing investments in the clean mobility sectors will show Michigan's commitment to this industry," Attanasio contended. "And its commitment to transitioning and supporting the automotive industry in its transition towards electric vehicles."

The Federal government's initial goal was to increase the total number of public EV charging ports to 500,000 by 2030. Since Congress approved the funding, the current administration may face challenges in stopping the program on its own.

After thousands of homes and businesses burned in the Los Angeles fires, public health doctors are warning about the toxic pollution from plastics used in construction. Many building materials are made from plastics, including flooring and carpeting, floor sealants, siding, insulation, paints, and plumbing.

Kaya Allan-Sugerman, director of health and environment programs with the group Physicians for Social Responsibility Los Angeles, said the toxic chemicals found in urban wildfire smoke has been linked to respiratory and developmental conditions, hormone disruption, and even cancer.

"Plastics don't just burn," she said. "They release some of the most toxic chemicals. When released, these pollutants don't just disappear. They can travel distances in the ash and they settle in the air, water and soil, contaminating entire communities."

Experts recommend using an air purifier or HVAC system with a HEPA filter inside, and wearing an N-95 mask outside if you're downwind of the fire zones. If you help clean up toxic ash, use gloves and avoid dry sweeping, which stirs ash into the air. Use wet methods or a HEPA vacuum instead, she suggested.

Allan-Sugerman said when rebuilding, people should choose safer, non-plastic materials wherever possible in order to promote public health, fire safety and environmental quality.

"We need stronger regulations on toxic building materials, and investment in sustainable fire resistant construction, because the more we use plastics in our buildings, the more we set ourselves up for long-term harm, especially as wildfires become more frequent and intense, given climate change," she explained.

She added that websites such as Habitablefuture.org can help homeowners find alternatives to plastic in building materials.

New legislation would transition more ocean-going container ships to run off electricity instead of diesel while they are docked at Washington ports. Proponents of the bill say implementing more shore power would improve air quality and cut emissions. Ships still need power when they are in port, and often leave engines idling. The diesel fumes have created health problems for nearby Puget Sound residents, including increased risk of cancer and other serious health effects.

Rep, Julia Reed, D-Seattle, introduced the shore power bill, and said both impacted communities and the shipping industry have high incentives to move away from diesel.

"We need both of these partners to kind of work together towards a common goal of creating shore power across Washington state in order to get this to work," she explained.

Reed noted the transition to electric power for Washington's ports will take years to implement and will be expensive, but added the shipping industry is motivated by the high cost of diesel to find alternative fuels, which are already in use in Europe and California.

Georgetown and South Park, two neighborhoods in Southern Seattle, as well as parts of Tacoma face severe health disparities due to the impacts of diesel fuel and other industries. Life expectancy is up to 20 years lower in these areas compared to other parts of the state. Reed says she recognizes this has been an issue for these communities for years.

"I think it's not an accident that a lot of poor browner communities tend to be the ones that are closest to these industrial impacts. And also those communities have been speaking out for themselves," she explained.

Reed said the coast electrification project will be funded in part by the Climate Commitment Act, which was upheld by Washington voters in 2024. The program uses a cap and trade system to help the state meet its goal of reducing greenhouse gas emissions by 95% by 2050.
