1a.Objectives (from AD-416):
Measure ambient concentrations of atmospheric components at the agriculture-urban interface of the Chesapeake Bay watershed. Results will be used to discern the fate and transport of agriculturally-related pollutants and their effects on air quality.
1b.Approach (from AD-416):
Measure atmospheric components at the agriculture-urban interface at one location in Beltsville, Maryland. Samples will usually be collected weekly or bi-weekly throughout the year. Samples will include particulate matter and semi-volatile and volatile organic compounds.
The goal of this Non Funded Cooperative project with USDA Natural Resources Conservation Service, Plant Materials Center, is to collect air samples periodically (weekly to bi-weekly) to measure gas phase contaminants (pesticides, volatile organic compounds or VOCs, and ammonia) and particle pollution (total suspended particles, PM10, and PM2.5). This work directly supports sub-objectives 1 and 2 of the parent project and will provide data to examine the effects of agricultural and urban pollutants on air quality. The site was prepared, power installed, and samplers deployed. Cooperator kept the PI informed of changes and maintenance issues at the site and participated in regular planning meetings. Data from samples collected will also be included in the database for the proposed Lower Chesapeake Bay Long Term Agro-Ecosystem Research network.
