From: Cardiac effects of seasonal ambient particulate matter and ozone co-exposure in rats
Schematic of concentrated ambient particulates (CAPs) and ozone (O3) co-exposure system showing concentrator, O3 generator, exposure chambers, and particulate matter (PM) and O3 monitoring systems. Receivers were placed within each chamber to monitor electrocardiogram, heart rate and body temperature. Particle concentration and sizing were tracked in real-time using a scanning mobility particle sizer and an aerodynamic particle sizer. Additional aerosol monitors (DustTrak and P-Trak) were used to track PM levels in real-time.
