How do weHow do we improve air quality improve air quality
in high-density in high-density areas?areas?
Focus on local air pollution that creates unhealthy pockets of air pollution that cumulatively impact people who are exposed

Reducing Local Air Pollution Levels Reducing Local Air Pollution Levels Requires Alternative Approaches Requires Alternative Approaches to Evaluate and Control Exposuresto Evaluate and Control Exposures
Pollution sources are often:• Numerous • Diverse • Mobile • Episodic• Affected by local meteorologic conditions

The Solution is Real-time, The Solution is Real-time, Integrated Sampling Integrated Sampling
and Evaluationand Evaluation Offers the best approach
for environmental assessment Completely integrates
environmental data Focuses on challenging,
polluted areas Allows immediate action
and observation

Integrated, Real-time Integrated, Real-time Air/Environmental Air/Environmental Monitoring allows us Monitoring allows us to:to:
Focus on air sampling of dust (multiple particle size) and total volatile organic compounds (TVOC) (gases, vapors)
Correlate measurement to wind speed and direction Include video, digital imaging, and other
environmental data Provide immediate graphic illustration of integrated
data

Benefits of Real-time Monitoring Benefits of Real-time Monitoring of Neighborhood Pollutantsof Neighborhood Pollutants
Measure effectiveness and return on investment (ROI) of controls to reduce pollution
Provide integrated data from all detectors within a single platform and in real time
Provide empirical data to test and better design air quality models and approaches

Policy Recommendations:Policy Recommendations:
Scientific Policy1. Launch pilot studies of sophisticated, integrated
real-time data monitoring systems in targeted high-density areas
2. Identify, test, and evaluate detector technology3. Focus research in measuring particulate size
concentrations as surrogates for improving local air pollution

Policy Recommendations: Policy Recommendations:
Legislative policy1. Analyze real-time empirical data
to develop consistent thresholds and approaches to reduce air pollution
2. Evaluate current practices in measuring air pollution and other environmental stressors at construction and hazardous waste sites
3. Develop consistent actions and controls when pollutants are at threshold
