Particulate Matter in a Changing World: Grants to Combat the Impacts of Climate Change

By Christina Burchette

There are certain things that are always changing: the weather, fashion trends, and technology (which iPhone are we on again?) are a few that come to mind. I can always count on the fact that these things won’t stay the same for long. But there are other things that I typically expect to remain the same: I expect to get hungry around lunchtime, I expect the bus to come every morning, and I expect to be able to breathe clean air. I don’t even think about the possibility of these things not happening—until something changes.

I definitely don’t think about air quality often or expect it to change. As long as I’m breathing and well, why would I? But in reality, air quality changes every day, and over time it may change a lot depending on how we treat our environment—and we need to be ready for these changes. This is why EPA recently awarded research grants to 12 universities to protect air quality from current and future challenges associated with climate change impacts.

Climate change is affecting air quality by influencing the type and amount of pollutants in the air. One type of pollutant present in our air is particulate matter, or PM. Long-term exposure to PM is linked to various health effects, including heart disease and lung function, and it doesn’t take a high concentration to affect our bodies. The more PM there is in the air, the more likely we are to be affected by health conditions.

With EPA Science to Achieve Results (STAR) grants, university researchers are approaching the future of air quality from multiple angles with a focus on learning more about the PM-climate change relationship. They will study the impacts of increased wildfire activity that generates PM, often called soot, in the Rocky Mountains. They will look at the impacts that climate change and land use change have on the development of dust storms in the West and Southwest; and they will evaluate the best means of energy production in California where air quality is among the worst in the nation to reduce health care costs and lower levels of PM and greenhouse gases.

Over the next few decades, climate change will be the catalyst for various environmental trends, so finding a way to manage the impacts of these trends is essential to protecting our health. The work these grantees do will help to inform air quality managers and others to make sustainable and cost-effective decisions that keep our air quality at healthy levels and protect public health and the environment. That way, future generations will think of good air quality as something we can expect.

Air Quality Awareness: A New Generation of Research

By Dan Costa, Sc.D.

Graphic of clouds and buildings in a silhouette cityscape. It’s Air Quality Awareness Week! This week, EPA is showing how we care about the air by announcing grants to three institutions to create air research centers. We now understand more than ever about the threats of air pollution to environmental and human health, but there is still more to learn. EPA has a history of supporting research and development that complements the work of our own staff scientists to bolster scientific knowledge about the effects of air pollution. EPA uses this knowledge to address many pressing questions and understand connections between our changing environment and human health.

Since 1999, EPA has funded three rounds of research centers through a competitive grant process. The scientific experts at these centers have contributed to a more complete understanding of the persistent air quality challenges that continue to face our nation. The first round of EPA funded air research centers focused on particulate matter and examined the link between particulate matter and cardiovascular disease. In 2005, the next round of centers focused on whether differing health effects could be linked to specific sources of air pollution. By 2010, it was clear that to get an accurate understanding of real life exposures, we needed to examine the health effects of exposure to multiple pollutants at once instead of just one or two at a time. The third round of centers took on this complex challenge. The next step is to delve into questions regarding how the health effects of air pollution may vary in different cities and regions across our country – each with its own unique characteristics and set of pollution sources.

This leads us to today and our exciting announcement–EPA is awarding $30 million through its Science to Achieve Results (STAR) program to fund the establishment of Air, Climate, and Energy (ACE) Research Centers at Yale University, Harvard University and Carnegie Mellon University. These Centers will consider changing energy production methods and local climate, while investigating the effects of global climate change, technology, and societal choices on local air quality and health.

I am eagerly anticipating the many new tools and ideas that will be produced by this next generation of EPA funded air research centers.

Schools, Children’s Health and the Environment

How do environmental hazards and policies affect children’s health and school performance?

Thanks to support from the EPA Science To Achieve Results (STAR) program, we explored those questions. Our project is the first to addresses multiple aspects of environmental health and schools, such as developing indicators related to school locations, and how to develop methodologies for assessing and improving school health.

With EPA support, we are: 1) developing and enhancing Environmental Public Health Indicators (EPHI) representing environmental hazards, children’s school performance, and health; 2) exploring new methodologies for assessing exposure sources; 3) assessing how school environments, along with location and socio-economic status affect children’s health; and 4) evaluating the effectiveness of efforts to protect children’s environmental health in New York, such as the New York State Clean air School Bus Program and school bus idling regulations.

EPA support also enabled us to extend or continue our previous activities, including: tracking how school building conditions and asthma hospitalizations change over time in New York; surveying school nurses, custodians, district facility directors, and teachers to identify environmental problems—and potential solutions—facing schools; and examining how the surrounding neighborhood, specifically a school’s proximity to facilities such as hazardous waste sites, major roads, or airports might increase childhood asthma risk. We also assessed the impacts of healthy school characteristics related to indoor air quality, ventilation, cleanliness, thermal comfort, lighting and acoustics on student attendance, academic performance, and respiratory health.

For example, our work showed an association between missed school days and certain poor conditions in the school: visible mold, humidity, poor ventilation, and vermin. Having six or more individual such building-related problems was also associated with student absenteeism. Further, these associations were strongest among schools in lower socioeconomic districts, and in schools attended by younger students. We also found district-level childhood asthma hospitalizations to be related to poor condition of roofing, windows, exterior wall, floor finishes, and boiler or furnace.

When looking at air quality, we found that the control policy for nitrogen oxides (NOx) may have had a positive impact on both state-wide and regional air pollution levels and respiratory health. The positive effect varied by children with different types of respiratory diseases, region, and socio-demographic characteristics.

Our EPA-supported research is providing important data and information, informing our work developing and implementing a sustainable school environmental health program for New York State. We have shared our findings with a Steering Committee consisting of approximately 50 key school environmental health stakeholders, including superintendents, facilities managers, teachers, state agencies, physicians and advocacy groups, and have been working on plans to address existing and emerging environmental problems challenging schools. With these efforts well under way, we fully expect our findings to lead to healthier students, teaches, and other school occupants throughout New York.
