Atmospheric Chemistry

The field of atmospheric chemistry is focused on improving our understanding of the composition and chemistry of the atmosphere and the impact of human activities. Current research topics in this area include the chemistry of photochemical smog, the interactions between the biosphere and the atmosphere, chemical reactions on environmental surfaces, and the fate of persistent organic pollutants in the atmosphere.

'Self-cleaning' pollution-control technology could do more harm than good, study suggests

6/13/13 
Research by Indiana University environmental scientists shows that air-pollution-removal technology used in "self-cleaning" paints and building surfaces may actually cause more problems than they solve.

Indiana University study finds flame retardant pollutants at far-flung locations

Research supports effectiveness of tree bark as novel sampling medium for contamination.

IU study finds increasing atmospheric concentrations of new flame retardants

12/14/11 
"We find that the environmental concentrations of these compounds are increasing rather rapidly," Hites said. "It's rare to find that concentrations of any compound are doubling within a year or two, which is what we're seeing with TBB and TBPH."

New Flame Retardant Levels Rising Rapidly

Air Pollution: Air concentrations of the brominated chemicals doubled every 13 months in recent years in Cleveland and Chicago.

Great Lakes Project Awarded $5 Million

11/4/09 
A project to measure levels of airborne toxic chemicals being deposited in the Great Lakes was recently awarded a $5 million grant from the U.S. Environmental Protection Agency. The Integrated Atmospheric Deposition Network (IADN), led by SPEA professor Ronald Hites and research scientist Ilora Basu, began in 1990 under an agreement between the U.S. EPA and Environment Canada. IU has been in charge of the U.S. portion of the study since 1994, and the grant will extend IU's oversight of the project for a further five years.
