2010 Annual Report
A new configuration of air sampling equipment for the three master stations has been designed. Air sampling equipment and parts have been purchased and assembly is ongoing with deployment scheduled for next year. This work has been bolstered by a new specific cooperative agreement with scientists at Oklahoma State University and ARS scientists Beltsville, Maryland and Las Cruces, New Mexico. This cooperative project aims to carry out research on the development and evaluation of atmospheric particle sample collection methods for agricultural operations.
Progress has also been made in launching a new research program area in regional atmospheric emissions and transport modeling. An ARS research associate has been hired with expertise in the area of air quality modeling, atmospheric chemistry, and engineering to address the modeling aspects of this work. Cooperative research ties were established with the Atmospheric Modeling and Analysis Division of USEPA and the ARS research associate will work directly with USEPA scientists to model the fate of agricultural pollutants in the Chesapeake Bay region. Initial meetings with USEPA have been fruitful, and a forum has been established for ARS and USEPA scientists to work together on several air pollution models. ARS scientists at Beltsville, Maryland, have also strengthened collaborative efforts with ARS scientists at Ames, Iowa, and Riverside, California, and have initiated modeling efforts using existing datasets.
Research efforts have been enhanced by two collaborative efforts funded by other agencies. The first project involves the environmental persistence, bioavailability, and volatility of flame retardant compounds in agricultural soils after biosolids applications. This work is being carried out in cooperation with the University of Maryland via a specific cooperative agreement (1265-12610-001-02S) and with the District of Columbia Water and Sewer Authority. The second is an AFRI funded project (1265-12610-001-01R) initiated in the fall of 2009 to measure emissions of different types of pollutants from large cattle feedlots and to continue development of novel chemical fingerprinting methods for particles to aid in source identification. This project is being conducted with scientists at Kansas State University and ARS scientists at Beltsville, Maryuland; Ames, Iowa; Bowling Green, Kentucky; and Florence, South Carolina.
