Objective:
- Characterize spatial and temporal gradients of selected air pollutants along roadways and within neighborhoods in MESA cities using a mobile platform.
- Measure spatial variation in concentrations of selected air pollutants at 2-week average stationary sites in coordination with the mobile measurements.
- Characterize aging of air pollutant components as they are transported from roadway sources to neighborhood receptor locations.
- Provide detailed characterization of laboratory exposure conditions available for toxicology testing, and identify likely conditions that mimic those found in urban settings.
Progress Summary:
Aims 1 and 2 continue as the main focus of activities in this year 2 time period. This phase of the study is conducting field sampling through 2013 across four cities in the MESA-Air cohort: Minneapolis/St. Paul, MN; Baltimore, MD; Los Angeles, CA; and Winston-Salem, NC. The instrument platform for mobile monitoring was assembled and tested in Seattle in October of 2011. Heating season measurements have been completed in Minneapolis/St. Paul and Baltimore; non-heating season measurements are completed in Baltimore and are under way in St. Paul. During each 2-week sampling period, the mobile monitoring platform measures concentrations of particles and gases while continuously on the move along a fixed sampling route with position information simultaneously logged by a real-time GPS. Data collection includes the following components: optical particle size in 31 size bins from 10 to 0.2 μm, particle mean diameter and particle count from 0.03 to 0.2 μm, total particle count >0.1 μm, particle light scattering coefficient, particle light absorption (black carbon), NO/NO2, O3, CO, CO2 and total VOCs.
