Abstract

BACKGROUND: Oxidative potential (OP) has been proposed as a measure of toxicity of ambient particulate matter (PM). OBJECTIVES: Our goal was to address an important research gap by using daily OP measurements to conduct population-level analysis of the health effects of measured ambient OP. METHODS: while controlling for other pollutants. RESULTS: remained a significant predictor of asthma and ischemic heart disease in most bipollutant models. CONCLUSIONS: as a measure of fine particle toxicity. https://doi.org/10.1289/EHP1545.
