Research Report 201 presents a study led by Dr. Lydia Contreras at the University of Texas, Austin, who is a recipient of HEI’s Walter A. Rosenblith New Investigator Award. Dr. Contreras and colleagues evaluated how exposure of lung cells to volatile organic compounds plus ozone affects oxidation of ribonucleic acid, a key component of cells. The study aimed to improve understanding of the biological mechanisms by which air pollutants can cause effects in human health, thereby expanding our knowledge of potential causal links between exposure and health.
