Research Interests -- Techniques of Analytical Radiochemistry Applied to Environmental Questions

The Clean Air Act and the Clean Water Act as amended requires the EPA to identify and assess atmospheric deposition of hazardous air and water pollutants.  Hazardous pollutants are listed and include trace elements such as mercury and arsenic.  Studies to characterize trace elements in ambient air and water have been carried out since the early 1980’s.  The objectives of these studies have been to collect and analyze ambient aerosol and water samples and identify probable source types and source regions for the observed trace element concentrations.

Automatic air samplers were used to collect and separate fine and coarse particles (PM-10 and PM-2.5 diameter particles).  Water samples are pre-concentrated by freeze-drying.  Trace element concentrations are determined using Instrumental Neutron Activation Analysis (INAA).  This technique allows the determination of elemental concentrations of over 40 elements at levels in the parts per million (ppm) and even parts per billion (ppb) range for some elements.  Data can be interpreted using statistical and meteorological methods to help explain the ambient atmospheric composition of trace elements for a given sampling site and the possible relationships to natural and anthropogenic sources.
