Abstract

As secondary aerosols become larger fractions of ambient PM2.5, emission factors and source profiles need to reflect the photochemical aging of multipollutant emissions that account for changes in transport between source and receptor. Oxidation Flow Reactors (OFR) intend to simulate gas/particle transformation and volatilization with time-scales of hours to days in order to estimate mass gains or losses due to atmospheric aging. The commercially-available Potential Aerosol Mass (PAM)-OFR (Aerodyne Research, LLC, Billerica, MA, USA) is evaluated for its feasibility in establishing an emission limit certification protocol for China and for determining changes to source marker abundances used in source apportionment model applications. ...
