Just what are the impacts of oil and gas development on the environment? Scientists observed key VOCs that are precursors for ozone production. A "mobile laboratory" found that air sampled near active gas wells and various processing plants contains just the right mix of ingredients. More on the Uintah Basin Winter Ozone Study and Utah's winter air quality mystery.

Soot is in the air! The burning of coal, diesel, biofuel, such as firewood, and biomass releases black carbon, a fine particulate that makes up soot. More on University of Colorado CIRES Spheres Magazine: 2011 Air Edition - black carbon research (pg 18) and black carbon released during the Gulf Oil Spill.
