A new study finds that the U.S. places with the most polluted air in the 1980s remain the most polluted today. Poor people and people of color are more likely to live in places with dirty air.
The EPA does not require companies to notify federal regulators if the pandemic interferes with pollution monitoring or reporting. That leaves states alone on the front lines of pollution control.
Car traffic took a big dip beginning in late March, and headlines celebrated clean air around the U.S. But an NPR analysis of EPA data tells a more troubling story.
The American Lung Association releases its State of the Air report every year, detailing the levels of particle air pollution and ozone in communities a
More Americans are breathing unhealthy air, even though overall air pollution has decreased in recent decades. In the tug-of-war between air regulations and climate change, global warming is winning.
A photo on social media showing Africa's second-highest mountain from Nairobi made many Kenyans cry foul. But the photo — shot on a day free of pollution, because of COVID-19 restrictions — is real.
India has ordered 1.3 billion people to stay home to prevent the spread of COVID-19. The lockdown seems to have inadvertently solved, at least temporarily, another public health crisis: air pollution.
Air pollution levels have dropped dramatically as power plants and factories have slowed down — potentially saving lives. But the public health benefits aren't so simple to calculate.
October marks not only fire season in California, but also the peak of the grape harvest. In areas not imminently threatened, some workers labor through heat and smoke to save harvests and paychecks.
If vehicles in central London don't meet emissions standards, their drivers must pay a daily fine. Six months into the new program, the city says the regulation is decreasing toxic air pollution.
Smog can spike during hot days. A new study finds that the effects of breathing air pollution may be cumulative. Long-term exposure may lead to lung disease, even among people who've never smoked.
Winter nights in Ulaanbaatar can drop to minus 20 degrees Fahrenheit. Many residents without electricity burn coal to heat their homes, leading to toxic air and health problems.
Scientists are making progress in identifying environmental hazards that contribute to cancer. Researchers say many cases could be avoided if the work is accelerated.
Seventeen automakers signed a letter to the Trump administration and California Gov. Gavin Newsom saying they want one set of policies to reduce greenhouse gases and make cars more fuel efficient.
In a new book, physician Sandro Galea calls for a change in how we talk about health in America. The real drivers of wellness, he argues, are not personal choice, but our history, policies and values.
New cases of asthma dropped dramatically in Los Angeles communities where air quality improved the most over 20 years. The results illustrate health benefits from pollution control.
A study ties an estimated 4,300 premature deaths a year to the air pollution caused by corn production in the U.S. In some regions, the per-bushel health costs exceed the corn's market price.
A research team tracked the diets and exposures to air pollution of kids inside Baltimore homes. Children with diets high in omega-3 fatty acids seemed less vulnerable to pollution's effect on asthma.
Some panel members said they don't agree that breathing sooty air can cause premature death. The panel's draft recommendations to the EPA would change how it assesses the dangers of air pollution.
Fine particulate matter floating through the murky haze that hangs over the city has reached harmful levels, leading the government to shutter more than 400 public schools.
