When it comes to the ultra-fine particles you may breathe in from polluted air, all is not created equal as it affects your health.
Fine particle pollutants known PM2.5 -- particles that are 2.5 microns or less in diameter -- appear to double the risk for premature death over time if they originate from coal-fired power plants versus other sources, a
Nearly half of Americans have never heard of health-threatening PFAS “forever chemicals,” a new survey has found.
PFAS (perfluoroalkyl and polyfluoroalkyl substances) are a category of thousands of manufactured chemicals that have become an emerging concern to environmental and human health, researchers from Texas A&M University said.
Air pollution from heavy traffic may be driving pregnancy complications and health concerns for infants.
Researchers who matched more than 60,000 birth records with air-monitoring data found that pregnant patients living in an urban area with elevated levels of nitrogen dioxide had higher rates of preterm birth.
This included delivery before 28 weeks, according to
More people around the world are exposed to wildfire smoke that has the potential to harm human health, and their numbers are growing, new research finds.
More than 2 billion people are exposed to at least one day of potentially health-impacting wildfire smoke each year, a figure that has grown by almost 7% in the past decade, according to a study led by Australian scientists.
Air pollution has long been known to harm the heart and lungs, but new research suggests it might also raise the risk of breast cancer.
Researchers at the U.S. National Institute of Environmental Health Sciences (NIEHS) and the National Cancer Institute (NCI) discovered that the largest increases in breast cancer incidence were among women who, on average, had higher levels of particulate...
As this summer has shown, the massive smoke plumes generated by wildfires can dirty the air of regions many miles away. Now a new study is raising the question of whether that pollution is contributing to suicides in rural America.
Researchers found a correlation between air pollution from "drifting" wildfire smoke and a rise in U.S. counties' suicide rates. The connection was not seen ev...
Smoke from Canadian wildfires sent high numbers of people suffering from asthma attacks to America's emergency rooms this spring and summer, according to two new reports.
From April 30 to August 4, 2023, smoke from out-of-control wildfires in Canada increased emergency room visits for asthma by 17% over average, according to data from the U.S. Centers for Disease Control and Prevention. ...
Doctors who overprescribe antibiotics are often blamed for medication-resistant illnesses, but new research points to another potential culprit: air pollution.
Controlling air pollution could reduce antibiotic resistance, greatly reducing deaths and economic costs, according to a new in-depth global analysis were published Aug. 7 in The Lancet Planetary Health..
The Canadian wildfires that are burning out of control have brought hazy skies and polluted air to parts of the United States unprepared for it -- and that's affecting not just the people, but their pets and livestock, too.
An animal welfare expert from the University of Illinois Urbana-Champaign offers some advice for animal caregivers to help them get their animals through these smoky...
Clouds of smoke continue to drift over the Eastern United States and Europe from wildfires in Canada, and experts are predicting a longer and more destructive wildfire season due to rising temperatures and drier conditions.
As a huge plume of smoke from over 400 Canadian wildfires swept south and turned New York City into a landscape that resembled Mars more than Earth, heart experts warned that air pollution can damage your heart as much as it damages your lungs.
It's obvious that wildfires can affect breathing and respiratory health, but exposure to this smoke can also cause or worsen heart problems, the ...
Consider yourself a lifesaver if you opt for an electric vehicle next time you buy or lease a new car.
Electric cars can save millions of lives and reduce health care costs by improving air quality so people can breathe better and freer, according to a new report by the American Lung Association. Zero-emission electric vehicles don't emit exhaust gas or other pollutants into the atmospher...
Large, uncontrolled wildfires in Nova Scotia are creating unhealthy air in the Northeast region of the United States, including parts of Connecticut.
This significant smoke plume is likely to cause elevated levels of fine particulate matter, the American Lung Association warned in its alert. Particulate matter contains microscopic solids or liquid droplets that are so small that they can ...
Two western U.S. states issued air quality alerts over the weekend as heavy smoke from fires blazing in Canada drifted south.
Both Colorado and Montana experienced air quality issues because of dozens of Canadian fires. A third state, Utah, noted that it was beginning to see smoke, while Idaho had experienced haze last week, the Associated Press reported.
Toxic chemicals that develop from car exhaust, smoking and backyard grilling might increase your risk of developing the autoimmune disease rheumatoid arthritis, a new study suggests.
These chemicals are called polycyclic aromatic hydrocarbons (PAHs). They form as coal, oil, gas, wood or tobacco burn. Flame grilling of meat and other foods also contribute to PAH formation, the researchers ...
Even as many U.S. nuclear reactors reach the end of their estimated life spans, the country still gets nearly 20% of its power from these sites.
Now, new research claims that shutting them down could increase air pollution and cause more deaths because while nuclear power plants are considered relatively clean energy, many potential replacement sources for nuclear power are not.
Exposure to air pollution may increase the risk of developing dementia, according to a review of prior research.
The new Harvard study is the latest look at a host of health issues — from dementia to heart disease and stroke — linked to pollutants such as fine particulate matter (PM2.5), as well as nitrogen oxide and nitrogen dioxide.
A new study is enough to take your breath way: Nearly no place on Earth is free of air pollution, it found.
The study "provides a deep understanding of the current state of outdoor air pollution and its impacts on human health. With this information, policymakers, public health officials and researchers can better assess the short-term and long-term health effects of air pollution and dev...
Exposure to elevated levels of air pollutants is associated with bone damage in postmenopausal women, according to a new study that said the effects were most evident on the lumbar spine.
High levels of niitrogen oxides in air nearly doubled the effects of normal aging on bone density in the spine, said researchers from Columbia University's Mailman School of Public Health in New York Cit...
People living in heavily polluted areas of the United States may be more vulnerable to Parkinson's disease, a new study suggests.
Specifically, the culprit is a type of air pollution called fine particulate matter (PM2.5), which is less than 2.5 microns in diameter and comes from car exhaust, burning of fuels in power plants and other industries, and forest and grass fires, researchers s...
Electric cars are still in the minority on America's roads, yet researchers are already seeing health benefits from reduced tailpipe pollution.
In a new California study, neighborhoods with the most all-electric cars -- called zero-emission vehicles -- saw a decline in asthma-related emergency room visits. Researchers believe this was a result of lower levels of nitrogen dioxide (NO2) in...
A mother-to-be's exposure to air pollution during pregnancy may have a lasting impact on her baby's brain development, new research indicates.
Toddlers scored lower on assessments for thinking, motor and language skills when their mothers had more exposure to pollutants during pregnancy, according to researchers at the University of Colorado Boulder.
While U.S. policymakers have attempted to lower lead exposure among children since the 1970s, new research finds that kids living near airports are still being exposed to dangerous levels of the heavy metal.
“Across an ensemble of tests, we find consistent evidence that the blood lead levels of children residing near the airport are pushed upward by the deposition of leaded aviation ga...
For the first time in a decade, the U.S. Environmental Protection Agency has proposed strengthening standards on fine soot in the air, a known contributor to serious health issues.
Under the new proposal, standards for fine particulate pollution, known as PM 2.5, would change from a level of 12 micrograms per cubic meter to a level between nine and 10 micrograms per cubic meter. The stand...
