Cellular and Acellular Assays for Measuring Oxidative Stress Induced by Ambient and Laboratory-Generated Aerosols

Research Report 197 describes a study by Dr. Nga (Sally) Ng and her colleagues to characterize and compare the oxidative properties of ambient particulate matter and laboratory-generated secondary organic aerosols through chamber experiments and field studies. The investigators created various PM exposure mixtures and measured the production of reactive oxygen species in both chemical and cellular assays. This study was funded under the Walter A. Rosenblith New Investigator Award.
