Expertise:
Dr. Eitzer is an expert in the analysis of organic contaminants in a wide variety of matrixes.  These contaminants can include industrial products such as polychlorinated biphenyls or agricultural chemicals such as pesticides.  The matrixes can include soil, water, air, food products such as fruit and vegetables, and matrices related to honey bees.  He has expertise in the analytical methods used to do these analyses including extraction and cleanup of samples. In addition, his expertise extends to the instrumental methods such as liquid chromatography/mass spectrometry and gas chromatography mass spectrometry used in the analysis of these samples.

 

Education:
Ph.D. in Analytical Chemistry, Indiana University 1989
B.S. Double Major in Analytical Chemistry and Environmental Science, University of Wisconsin at Green Bay 1982

 

Station career:
Assistant Agricultural Scientist, 1998-2004
Associate Agricultural Scientist, 2004-2014
Agricultural Scientist, 2014-present

 

Past research:

The focus was on the environmental transport and fate of organic chemicals.  This included work on the measurement of dioxins in fish, the volatilization of pesticides from soil, and the translocation of pesticides from soil to plants.

Current research:
The current research falls into 2 categories.

 

The first major area of research concerns pesticides and bees.  One factor in many of the problems encountered by honey bees and other pollinators is the use of pesticides in both agricultural and residential settings.  These chemicals can have both acute and sub-lethal effects to these important species.  In addition, these effects are intertwined with other stressors such as fungal diseases, or varroa mites.  To elucidate some of these effects Dr. Eitzer has been collaborating with researchers across the country.  His role in these collaborations is to provide the data on pesticides in many matrices related to bees, so that the exposure of bees to pesticides can be assessed.


The second area of research is on the development of methods and the use of liquid chromatography/mass spectrometry to analyze organic contaminants in foods.  These methods are important to help protect the food supply from both intentional and unintentional adulteration.  One current focus in this area is on the use of liquid chromatography/high resolution mass spectrometry as the instrumental procedure rather than a more traditional tandem mass spectrometric approach.  This newer technique has the inherent advantages of being able to test for more compounds per analytical run, as well as the ability to look at the data retrospectively for analytes which were not considered at the time of acquisition.  This research is being conducted in collaboration with the Food and Drug Administration and other researchers in the Cooperative Agreement Program of the Food Emergency Response Network (FERN).
