Abstract Number: 557 Working Group: Aerosol Exposure
Abstract We tested different commercially available masks to determine the reduction in exposure and dose of fine particulate and black carbon that each might provide. We evaluated them inside the Bogota’s BRT buses, on a pedestrian route in the city’s downtown area and on a bike path using two sets of DustTrack DRX (TSI, Shoreview, MN) and AE51 microaethalometer (AethLabs, San Francisco, CA). One set sampled air directly from the microenvironments whereas the other did it through the masks. We used a mannequin head as an adapter for the masks to the inlets of the instruments and to take in to account how the masks fit. Both sets operated simultaneously and concentrations measured were used to estimate a possible reduction in exposure and potential inhaled dose of aerosols. Results might be used to show citizens how to reduce their exposure during commutes in a megacity and to point towards the most effective way to prevent effects during an air pollution episode.
