Objective:
Roadway-source air pollutants encompass a diversity of chemicals, including both particulate and gas phase components that are transformed by chemical and physical reactions as they age in the environment. Consequently, human exposures to air pollutants can range from relatively un-aged to highly aged components that vary with respect to particle size and the chemical composition of particle and gas phase components. To obtain a more comprehensive understanding of the seasonal and spatial variability in the concentration and composition of air pollutant exposures within MESA-Air cities, we employ mobile and fixed site monitoring to assess both gas and particle components of these pollutants as they age from roadway sources to population areas. The main project objectives are:
Progress Summary:
Aims 1 and 2 have been the main focus of activities in this period. During this startup phase a field sampling schedule has been defined across all cities, through 2013. We have been working on assembling the instrument platform for mobile monitoring that will be conducted in the four MESA Air cities: Minneapolis/St. Paul, MN, Baltimore, MD, Los Angeles, CA, and Winston-Salem, NC. Each city will be measured during the heating and non-heating season, during a 2 week long sampling period. This mobile monitoring instrument platform is designed to measure concentrations of particles and gases while continuously on the move with position information simultaneously logged by a real-time GPS. We have ordered and received most of the instruments and are programming a custom Lab View interface to perform the data acquisition to a laptop.
Future Activities:
Two pilot projects are scheduled for equipment testing. The first, a limited equipment test, will take place in the first week of August 2011, in the local Seattle neighborhoods. The second, a full-scale systems test, will take place in Tacoma, WA, retracing areas where the previous Tacoma mobile monitoring study took place. Additionally, we are working with current University of Washington students and staff in two of the four cities (Baltimore and Los Angeles) scheduled to be sampled, having them drive example mobile monitoring routes for time and driving feasibility. They also will define criteria for selecting and documenting fixed sampling site locations. We anticipate starting field measurements in November and continuing over the next 2 years. The laboratory test environment measurement campaign currently is planned for the fall of 2012.
