Objective:
Roadway-source air pollutants encomass a diversity of chemicals, including both particulate and gas phase comonents which 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 resect to article size and the chemical composition of article and gas phase components. To obtain a more comprehensive understanding of the seasonal and spatial variability in the concentration and composition of air pollutant exosures within MESA-Air cities, we employ mobile and fixed-site monitoring to assess both gas and article components of these pollutants as they age from roadway sources to population areas.
The main project objectives are:
1. Characterize spatial and temoral gradients of selected air pollutants along roadways and within neighborhoods in MESA cities using a mobile platform.
2. Measure spatial variation in concentrations of selected air pollutants at two-week average stationary sites in coordination with the mobile measurements.
3. Characterize aging of air pollutant components as they are transported from roadway sources to neighborhood receptor locations.
4. Provide detailed characterization of laboratory exposure conditions available for toxicology testing, and identify likely conditions that mimic those found in urban settings.
Progress Summary:
The bulk of Project 1 was completed in the first five years of the Center. Work over the last year has focused primarily on data analysis and manuscript preparation. Recent publications include manuscripts on the impacts of air pollution at the US-Mexico border (Galaviz et al. 2015) and near airports (Riley et al. 2016a). We have also recently published a paper investigating the correlations between mobile and passive badge monitoring data (Riley et al. 2016b). Project 1 researchers have also supported Project 5 and Biostatistics Core researchers with data preparation and data analysis for the multipollutant exposure analysis piece of that project and Project 4 researchers with data collection for the commute exposures.
Future Activities:
Activities in the next year will focus on manuscript preparation. Work on publications and dissemination of results is underway and will continue in the remaining no-cost extension period.
