Modeling Research Shows How Salty Ocean Air Impacts Ozone Pollution

Did you know that salty air from the ocean’s surface can help to reduce ozone air pollution, particularly in coastal areas?

EPA Projects Aim to Improve Ozone Models Over Long Island Sound

EPA scientists are using data from a 2018 study with partners where they collected air quality data to investigate ozone formation over the ocean and transport across Long Island Sound to improve air quality models.

Meet EPA Biologist Haiyan Tong MD, Ph.D.

Workshop on Performance Targets for Low-Cost Air Sensors Scheduled for July 16

EPA Model Shows Potential in Unraveling the Mystery of Lightning’s Impact on Air Quality

How does lightning contribute to air pollution? EPA researchers simulated the impact lightning has on ground-level ozone across the continental United States. This research will ultimately aid states in efforts to help protect our air quality.

The Legacy of EPA’s Acid Rain Research

In EPA’s 50 years of research, one of the most significant environmental challenges the nation faced was the problem of acid rain.

Study Assesses Long-Term Capabilities of Air Sensors

There are still many uncertainties about the operating and performance capabilities of low-cost air sensors.

Study Examines if Long-Term Exposure to Ozone Impacts the Cardiovascular System

An EPA study, called MESA Air Next Stage, looks at the relationship between ground level ozone and the changes over time in the health of arteries that feed both the brain and heart.

The Links Between Air Pollution and Childhood Asthma

The estimated six million children in the United States with asthma are especially vulnerable to air pollution. Read about three recent EPA studies on the link between childhood asthma and air pollution.

Understanding Indoor Air Quality During Wildfires

After wildfire smoke impacted the city of Missoula, Montana in the summer of 2017, the local health department was inundated with inquiries about the risks of smoke, actions to take, and how to create clean air spaces indoors.

Advancing Technology to Study the Toxicity of Wildfire Smoke

In a laboratory in Research Triangle Park, NC, researchers built a tube furnace system to precisely generate different types of smoke to assess how fuel composition and combustion conditions affect the chemistry and subsequent toxicity of biomass smoke.
