Wildfire PM2.5 differs from routine air pollution by composition, with higher elemental and organic carbon fractions that ...

Polycyclic aromatic hydrocarbons (PAHs) are typical organic compounds found in cigarette smoke and vehicle exhaust. In addition, PAHs are produced from incomplete combustion of organic material and ...

The amount of environmental exposure to polycyclic aromatic hydrocarbons, or PAH for short, is strongly linked to a person's risk of developing rheumatoid arthritis, suggests research published in the ...

In most situations, breaking things apart isn't the best way to solve a problem. However, sometimes the opposite is true if you're trying to characterize complex chemical compounds. That's what Sandia ...

Polycyclic aromatic hydrocarbons (PAHs) are typical organic compounds found in cigarette smoke and vehicle exhaust. In addition, PAHs are produced from incomplete combustion of organic material and ...

Wildfire smoke covering Michigan may not smell like a pleasant campfire because of chemical compounds in the smoke. Why it's ...

Whenever an organic matter is burned, such as in a wildfire, a power plant, a car's exhaust, or in daily cooking, the combustion releases polycyclic aromatic hydrocarbons (PAHs) - a class of ...

Wildfires create compounds called polycyclic aromatic hydrocarbons (PAHs), which are formed in the combustion process at high temperatures. These compounds are highly toxic. New research examined how ...

Federal scientists based in Seattle and Alaska have found that oil — by impairing heart functions — can cause serious harm to herring and pink salmon at far lower concentrations than previously ...
