Abstract Measurement of aerosol (or particle) surface area has been interest of aerosol community. Aerosol surface area is a good measure of adsorbed (toxic) material particles carry into the lung, therefore it should provide a good correlation with particle health effects. While BET surface area is an ideal measure, it is not practical for routine air monitoring purpose due to the sophisticated set up and procedure required for the measurement.
The presentation will re-illuminate definition of different types of aerosol (or particle) surface areas such as BET, Fuchs, and active surface area and discuss limitation and capability of aerosol surface instruments. Some suggestions will be made with respect to what the best surface area would be if we consider to use it as an alternative metric for ambient monitoring and source testing. If time allows measurement data from source testing for light duty vehicles, on-road air monitoring, and ambient air monitoring will be presented as well with respect to evaluating usefulness of aerosol surface area measurement as an alternative metric.
