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 ...

Does where you live affect your risk for lung cancer? Just possibly, experts warn.

Although cigarette smoking is the principal cause of most lung cancers, new research has found evidence that Americans who live in areas where air quality is poor may be at greater risk...

Pollutants produced by the U.S. oil and gas industry cause thousands of deaths and cost the country tens of billions in health care expenses, a new study reports.

Nitrogen dioxide (NO2), fine particulate matter and ozone all contribute to air pollution, and all are emitted as part of oil and gas production, the researchers said.

The new study estimates that the oil and gas industry ...

Nearly one-third of Americans live in counties with unhealthy air, according to a new report from the American Lung Association.

One in three, or 120 million, people lives with unhealthy levels of ozone or particle pollution, the “State of the Air” report says.

While air quality has improved overall, there are major differences between Eastern and Western states and in air poll...

The U.S. Environmental Protection Agency wants to put the pedal to the metal in America's transition to clean electric vehicles.

The EPA today announced proposed federal emissions standards aimed at accelerating the move to electric cars and trucks.

Once adopted, the standards are expected to create a massive improvement in air pollution across the nation, particularly in smog-choke...

The Environmental Protection Agency on Tuesday proposed limiting the use of a chemical used to clean medical equipment in sterilizing plants because it also raises cancer risks for workers.

The agency plans to slash emissions of the odorless gas, called ethylene oxide, by about 80% at 86 medical sterilization facilities.

“EPA's number one priority is protecting people's health and...

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.

P...

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.

The findings support the need to streng...

While all Americans could benefit from proposed new limits on what's called PM2.5 air pollution, new research indicates the change has the potential to benefit Black and low-income Americans the most.

The limits being considered by the U.S. Environmental Protection Agency (EPA) could cut death rates in those more vulnerable groups by up to 7%, according to researchers from Harvard T.H. C...

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...

Sewage-polluted Southern California coastal waters become airborne in sea spray aerosol, and can spread to people on land, even beyond the beach, according to a new study.

For this research, scientists sampled coastal aerosols at Imperial Beach in San Diego County and water from the Ti...

Children in Sweden's capital can breathe a little easier.

As Stockholm's air has gotten cleaner, young people's lungs have gotten stronger, new research shows. The findings could have implications for cities worldwide.

While the adverse impact of air pollutants on kids' lung health is well-documented, the impact of changes in air quality on lung development is less studied, research...

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...

Causes of different kinds of dementia vary, but about 40% are affected by risk factors a person can influence through lifestyle choices.

Two University of Michigan neurologists offer 10 tips for modifying those risks.
