Gas Station Pollution

 At gas stations, unburned hydrocarbons are chronically released to the environment. Adverse effects on public health are poorly understood. We perform laboratory experiments and modeling studies in order to identify and quantify relevant exposure pathways. We have also begun performing comprehensive risk and econometric analyses in order to assess the public health burden of the chronic hydrocarbon releases.
