New research on horses and dogs found elevated levels of PFAS "forever chemicals,"establishing horses as sentinel species.

Sentinel species provide advance warning of a danger to people.

The work also advanced knowledge about PFAS exposure and liver and kidney function in these animals. PFAS stands for per-and polyfluoroalkyl substances, a group of chemicals used in plastics and gre...

Using gas stoves can increase indoor air levels of benzene, a chemical linked to higher risk of leukemia and other blood cell cancers, a new study reports.

Analysis of dozens of stoves revealed that a single gas cooktop burner on high or a gas oven set to 350 degrees Fahrenheit can raise indoor levels of benzene above those typically released by secondhand tobacco smoke, the researchers r...

Black and Hispanic communities in the United States are more often poor -- and also more likely to have harmful levels of per- and polyfluoroalkyl substances (PFAS) in their drinking water, a new study reveals.

Sources of PFAS pollution -- including major manufacturers, airports, military bases, wastewater treatment plants and landfills -- are disproportionately sited near watersheds that...

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 ...

Many common household products emit airborne toxins that can harm your health in ways up to and including cancer, a new study reports.

Dozens of different types of consumer products contain toxic volatile organic compounds (VOCs), chemicals that escape as gases and accumulate in indoor air, researchers from the Silent Spring Institute and the University of California, Berkeley (UC Berkele...

Jobs that regularly expose you to certain chemicals appear to steadily increase your risk of pancreatic cancer, a new analysis reports.

People with more than 20 years of exposure to some chemical agents had a 39% increased risk of pancreatic cancer, compared with an 11% higher risk for 11 to 20 years' exposure and a 4% higher risk for 1 to 10 years' exposure, researchers found.

Black and Hispanic women who work as hairdressers are exposed to an array of chemicals, including many that have not been previously identified, a small study finds.

Researchers found that compared with women of color in office jobs, hair stylists had higher levels of various chemicals in their urine. Those substances included expected ones -- ingredients known to be in salon products -- ...

The air where you work could be increasing your risk of developing rheumatoid arthritis, a new study suggests.

Breathing in the fumes from commercial vapors, gases and solvents -- and even common dusts found in the workplace -- appears to increase chances of the chronic autoimmune joint disorder, researchers reported Dec. 6 in the
