Jeffery R. Meinertz

Position title:  Research Physiologist

Email:  jmeinertz@usgs.gov
Phone: 608.781.6291
Fax: 608.783.6066

Education:
1985, B.S., Biology, University of Wisconsin-La Crosse
1989, M.S., Biology, University of Wisconsin-La Crosse

Primary responsibilities/activities: 
As a principle investigator for the Fishery Management Chemicals and Aquaculture Drug team, my research efforts focus on developing data to gain the approval of new aquaculture drugs and to expand the uses of existing aquaculture drugs.  My data development efforts reside with determining total drug residue and metabolite depletion profiles, determining an aquaculture drug’s marker residue depletion profiles, and developing and validating analytical methods for aquaculture drug residues in water and fish tissue.
 
As a principal investigator for the Pharmaceuticals and Personal Care Products team, my research efforts focus on developing techniques to assess chronic impacts of pharmaceuticals and personal care products on aquatic invertebrates.  Current efforts are focused on the development of techniques to chronically expose daphnia to pharmaceuticals in a flow through test system and techniques to rear juvenile mussels in a chronic exposure laboratory test system.

Research interests: 

• analytical chemistry
• metabolism and depletion of drugs by fish
• the effects of pharmaceuticals and personal care products in aquatic environments

Active projects: 

• Evaluation of an analytical method for determining concentrations of isoeugenol in fillet tissue from cold, cool, and warm water fish species (Fishery Management Chemicals and Aquaculture Drugs team)
• Determination of an approach to assess the impact of emerging contaminants on aquatic invertebrates in national parks:  A project for the St. Croix National Scenic Riverway (Pharmaceuticals and Personal Care Products team)
