Short summary
The oxidative potential (OP) of ambient particulate matter (PM) has recently gained attention as an alternative metric for assessing the ambient PM toxicity. However, a major constraint in measuring the OP is its labor-intensive protocol. Here, we developed a new online instrument by coupling a mist chamber to an automated analytical system which can measure the real-time OP of ambient PM. We also report for the first time, the hourly averaged diurnal profile of ambient PM OP at an urban site.
The oxidative potential (OP) of ambient particulate matter (PM) has recently gained attention as...
