| Description: |
| The role of the atmosphere is typically not adequately considered in design of site remediation, other than rather crude assessments of fugitive dust emissions. By the same token, the importance of emissions from contaminated urban soils and surface waters as sources of hazardous air pollutants is poorly characterized. Thus two large national efforts, brownfield remediation and urban air quality management, have traditionally not been coordinated, neither in research, monitoring or regulatory arenas. To explore possible synergisms between these efforts, exploratory research is required to demonstrate the linkages between emission from (and deposition to ) contaminated soils and waters and regional air quality. the broad objective of this study is to link emissions from contaminated sites in the Baltimore urban area to ambient levels in the atmosphere in order to better understand the role of brownfields on regional air quality. Recently-developed, field tested sampling and analytical methods will be used to measure a broad suite of inorganic and organic species, and the resulting data will be interpreted using multivariate techniques. |
| Objectives: |
| 1. To enhance the
capability to measure releases of hazardous chemicals from urban
brownfield sites 2. To demonstrate the utility of highly resolved, sensitive measurement techniques to characterize the chemical composition of gases and aerosol particles in ambient air over two contrasting urban brownfield sites. 3. To enhance existing source apportionment techniques to better define the role of diffuse emission sources of hazardous air pollutants to the Baltimore atmosphere. |
