Impact/Purpose:

1) Develop methods of ecological exposure (e.g. rapid , sensitive analytical screening methods for a select list of antibiotics widely used in agriculture primarily in CAFOs (confined animal feeding operations).

2) Do Measurements & Provide data for multicompartment models of fate and transport.

3) Study biomagnification of specific chemicals and toxic metals.

4) Study specific pharmaceuticals:

*Determine the routes of entry and the impact of environmental factors such as rainfall on the movement and survivorability of selected antimicrobials in the environment.

*Determine if the entry of agriculture based antibiotics into the environment contributes to resistance in bacterial populations.

*Determine the contribution from municipal waste water treatment plants to antibiotic loading in the environment.

5) Develop methods for the analysis of alkylphenol ethoxylates and derivatives.

Description:

The multi-organizational Urban Dispersion Program (UDP) has been conducting tracer release experiments at various locations within the United States. In March 2005 the UDP conducted the first NYC based experiment called Madison Square Garden -05 (MSG05). The field study involved the release of six perfluorocarbon tracers (PFT) to the ambient air at designated locations around the Facility. The suite of tracers used at each site was different so that the influence of different emission sources at the PFT site can be differentiated. The general measurement program included stationary PFT monitors strategically placed at defined horizontal and vertical locations, and a complex array of meteorological equipment to measure near field and mesoscale wind speed, wind direction, etc. in the vertical and horizontal directions around the MSG. One of the four main goals of the UDP for New York City is "transferring improved capabilities for understanding the movement of contaminants to NYC emergency agencies." A component of the study being used to achieve this goal is having for the first time during an UDP a series of planned simultaneous prospective personal exposure measurements made on 12 individuals (i.e. EPA employees) during and after tracer release. The specific patterns of exposure selected for each personal monitor were designed to mimic the activities of EMS personnel, commuters, and other outdoor workers who could be expect to be present around the MSG facility during and after an accidental or deliberate release of a toxic agent. The discussion will present the design of the prospective exposure measurement program that is making use of personal monitors for PFT. In particular, the discussion will focus on how well the activities are being integrated into the overall UDP-MSG05 study.
